United Kingdom – Air Travel

What is the standard of domestic air travel in the UK like, and which routes and destinations are served?

In 2024, the UK carried the third highest number of air passengers of any country in the world, surpassed only by the United States and China. Yet despite this impressive international standing, the domestic aviation picture tells a more complicated story. Internal UK flights have fallen by more than half over the past two decades, declining from a high of over 450,000 flights in 2006 to approximately 213,000 scheduled for 2025.

Travellers are increasingly seeking greener and more cost-effective ways to get around domestically, prompting airlines to cut internal services and focus on more lucrative routes. This transformation has coincided with a significant resurgence in rail usage: the Office of Rail and Road recorded a 50% increase in rail journeys, rising from 1.15 billion passengers in 2005/6 to nearly 1.73 billion in 2024/5.

Even so, domestic aviation continues to serve a genuinely vital function across many parts of the UK. Data shows that 38% of passengers on Scottish island flights were travelling to or from Glasgow, 23% to or from Aberdeen, and 15% to or from Edinburgh. For communities in the Highlands, Orkney, Shetland, the Hebrides, and other outlying islands, flights are not a matter of convenience — they are frequently the only viable transport option. Unlike countries such as France or Germany, where high-speed rail networks have largely made short-haul domestic aviation redundant, the UK’s geography preserves aviation’s central role in connecting its more remote populations.

According to Cirium data, almost 600 million available seat miles (ASMs) were scheduled for April 2024 across more than 18,500 UK domestic flights. The highest-capacity corridors link London with Scotland: the London Heathrow to Edinburgh route tops the list, with British Airways scheduling 345 outbound and 346 return flights during April 2024 alone.

The average distance covered on a UK domestic flight is 277 miles — considerably shorter than typical domestic routes in countries such as Australia or the United States, where vast distances make aviation universally necessary. In the UK, the decision to fly rather than take the train needs to be evaluated on a route-by-route basis.

Which airlines operate domestic routes in the UK, and are any low-cost carriers available?

easyJet, British Airways, Ryanair, and Loganair are the dominant players, collectively accounting for 62% of all departures from UK airports. Competition is particularly strong on the main intercity corridors, and the involvement of several budget carriers keeps ticket prices accessible on popular routes.

For April 2024, easyJet held the largest share of UK domestic flights, operating 6,098 services with 1,056,112 seats on offer — representing roughly half of total domestic seat capacity. A British low-cost carrier headquartered at London Luton Airport, easyJet operates an extensive network spanning the UK and Europe, built around affordable point-to-point travel.

British Airways is the UK’s largest airline overall, offering a comprehensive mix of domestic and international services. Domestic destinations on the BA network include London, Edinburgh, Glasgow, Manchester, Inverness, Aberdeen, and the Isle of Man. BA holds particular importance for travellers requiring connections through Heathrow, as the flag carrier operates from both London Heathrow and London City — airports that sit closer to central London than the bases typically used by budget operators such as easyJet and Ryanair.

Loganair holds the distinction of being the UK’s oldest operational airline. Scotland-based and focused on Highlands and Islands connectivity, Loganair schedules a volume of domestic flights that comes close to matching British Airways, though its passenger capacity is far smaller given its preference for compact aircraft. For expats living in or travelling to remote Scottish communities, Loganair frequently represents the sole scheduled air service on offer.

Jet2 operates primarily as a low-cost European leisure carrier but also runs a selection of domestic UK routes. Its principal base is Leeds Bradford International Airport, supplemented by operations at Manchester, Belfast International, Edinburgh, Newcastle, East Midlands, and Glasgow International. Ryanair, although an Irish-headquartered airline, maintains a substantial UK presence and operates certain domestic sectors, chiefly from London Stansted.

How do you book domestic flights in the UK — what are the options and which booking platforms are available?

Arranging a domestic flight in the UK is a simple process, with several convenient channels to choose from. The most direct approach is booking through individual airline websites — British Airways, easyJet, Loganair, Ryanair, and Jet2 all maintain well-designed websites and mobile apps for booking, managing reservations, and checking in. Booking directly with the airline is often the best approach, as it provides the clearest picture of the total cost and ensures you have direct access to customer service should anything go wrong.

Third-party comparison and booking sites are also widely relied upon across the UK. Skyscanner — founded in Scotland and widely popular throughout the country — aggregates fares from a broad range of airlines and is a favourite tool for comparing prices at a glance. Google Flights, Kayak, Expedia, and Opodo are similarly well-used. Those who prefer a more personalised booking experience can still turn to established travel agencies, both online and on the high street — Trailfinders and Flight Centre being common choices, particularly for itineraries that combine domestic and international legs.

Although domestic airline fares change frequently, fares tend to be at their lowest in October. On high-traffic routes such as London to Edinburgh or London to Belfast, booking well in advance is strongly advised to secure the best prices. On Loganair’s island routes, where operator choice may be limited to a single airline, early reservation is equally important — especially through summer. Last-minute seats on trunk routes may be available, but prices typically climb steeply as the departure date approaches.

Online and mobile check-in is standard practice across all major carriers. easyJet, for instance, opens online and mobile check-in between 30 days and 2 hours before departure, while airport check-in closes 40 minutes before the flight. Specific policies vary between airlines, so always review the terms of your particular booking before travelling.

What do domestic flights typically cost in the UK, and what should expats budget for?

Domestic airfares within the UK fluctuate considerably depending on the route, the airline, and how far ahead you book. On routes served by several budget carriers — such as London to Edinburgh or London to Belfast — promotional one-way prices can occasionally fall below £30, though fares of £60–£120 one-way are more representative when purchasing a few weeks in advance (as of 2025). Check airline websites directly for current pricing, as fares shift frequently.

Given the number of low-cost operators on domestic routes, flying can sometimes undercut equivalent long-distance rail fares. However, this is not a universal rule — particularly when airport transfer costs, baggage charges, and the time required to get through check-in and security are factored into the overall equation. On routes with strong rail alternatives (London to Manchester being a prime example), the train is often faster from door to door and may be similarly priced.

Hold luggage is frequently not included in the base fare, and this cost may not be immediately visible at the point of initial booking. Baggage allowances can be a decisive factor when choosing between airlines. Budget operators such as easyJet and Ryanair levy separate charges for checked bags, seat selection, and various other extras, which can add meaningfully to the advertised headline price. The UK’s Civil Aviation Authority (CAA) publishes an airline charges comparison table (as of February 2025) that covers fees from major carriers including British Airways, easyJet, Ryanair, and Jet2.

On routes monopolised by a single operator — many of Loganair’s island services fall into this category — fares tend to reflect the absence of competition and can be considerably higher per mile than on busy trunk corridors. The broader decline in domestic UK flying has been driven by changing passenger preferences and a strategic withdrawal by airlines that reduced internal services following the doubling of Air Passenger Duty rates in 2007. Air Passenger Duty (APD) is a government tax levied on all departing flights from UK airports and is incorporated into the ticket price, adding a further cost element — particularly noticeable on domestic journeys.

What are the main international airports in the UK, and which ones are most relevant for expats?

London operates what is currently the world’s busiest city airport system, with six major airports collectively serving tens of millions of international and domestic passengers. In 2025, more than 302 million passengers passed through UK airports in total, with London’s hubs driving much of that volume.

London Heathrow (LHR) is the UK’s undisputed aviation flagship. Heathrow set an all-time passenger record in 2025, handling 84.5 million travellers. As a leading global hub, it serves as the home base for British Airways and Virgin Atlantic, linking London to virtually every region of the world. Situated 24km west of central London, the airport has five terminals. Transport connections into the city are excellent: the Heathrow Express reaches Paddington in 15 minutes (£25 single), the Elizabeth Line takes 30–40 minutes (£12.80), and the Piccadilly Line Underground takes 50–60 minutes for £5.50.

London Gatwick (LGW) is the UK’s second-busiest airport. Located to the south of London, it is a major base for low-cost carriers including easyJet and handles a large share of long-haul leisure traffic. The Gatwick Express provides a dedicated non-stop service to London Victoria in 30 minutes, while Thameslink and Southern rail services link the airport to London Bridge, Blackfriars, and St Pancras.

London Stansted (STN) serves as Ryanair’s primary UK base. In 2025, Stansted officially passed the 30-million-passenger mark, cementing its role as the country’s main gateway for European budget travel and serving more European destinations than any other UK airport. The Stansted Express connects the airport to Liverpool Street in 47 minutes (£16).

London Luton (LTN) is a significant hub for budget airlines. Following considerable recent investment, including the construction of the Luton DART transit link, Luton has become a major base for Wizz Air and easyJet, with routes concentrated across Europe and the Middle East.

London City (LCY) is the capital’s most centrally located airport. Positioned in the Royal Docks, it is the only airport within London’s inner zones, and while its passenger throughput is lower owing to its compact size and short runway, it offers an exceptionally swift kerb-to-gate experience. London City Airport is served by Docklands Light Railway (DLR) trains within Zone 3 of the London Underground network.

Beyond London, Manchester Airport is by a significant margin the largest and busiest airport outside the capital, serving a catchment area of around 20 million people. Manchester recorded 30.9 million passengers in 2024 and offers connections to over 200 destinations worldwide. Expats settling in northern England, the Midlands, or Scotland will find relevant options including Birmingham Airport, Liverpool Airport, Bristol Airport, Glasgow International Airport, Leeds Bradford, Edinburgh, and Newcastle.

Are there any rules, restrictions, or practicalities at UK airports that expats should be aware of?

Identification for domestic travel: A passport is not required for flights within the UK. It is nonetheless sensible to carry photographic identification at all times. Accepted forms of ID include a valid passport, a driving licence, or a national identity card from an EU/EEA country. Always confirm the current requirements with your specific airline before departing, as policies can differ between carriers.

Arriving into the UK from abroad: From 2025, most visa-free visitors are required to hold an Electronic Travel Authorisation (ETA) at a cost of £16. Expats who hold valid leave to remain, or who have settled or pre-settled status under the EU Settlement Scheme, are exempt from this requirement. Always consult the latest guidance on the official GOV.UK website before travel, as immigration rules are subject to change.

Check-in times: For domestic UK flights, arriving at the airport at least two hours before departure is advisable. During peak travel periods, allowing three hours is a sensible precaution. For international departures from major hubs such as Heathrow or Gatwick, arriving three hours before departure is the general recommendation.

Baggage allowances: Hold luggage is frequently not included in the base fare and may not be displayed in initial pricing. Budget carriers apply strict policies on bag dimensions and weight limits, and passengers who exceed these at the gate can face substantial penalty charges. Always verify your baggage allowance before you travel and refer to the CAA’s airline charges comparison for up-to-date fee information.

Passengers with reduced mobility: Passengers with reduced mobility have a legal right to assistance — commonly referred to as ‘special assistance’ — when travelling by air. Both airports and airlines are obliged to provide this support free of charge. You should request assistance either at the time of booking or at least 48 hours before your flight.

ATOL protection: When you book an ATOL-protected flight or package holiday through a single travel company, everything listed on your ATOL Certificate is financially protected if that company ceases trading. Before completing any booking, confirm that the company holds a valid ATOL licence.

How does air travel connectivity in the UK affect day-to-day expat life?

For most expats who settle in major urban centres — London, Manchester, Birmingham, Edinburgh, or Glasgow — domestic air travel is rarely a day-to-day necessity. A comprehensive network of rail and coach services covers the vast majority of intercity journeys efficiently, and in many cases more conveniently than flying once airport travel time is taken into account. The UK’s rail infrastructure, unlike that of countries with limited surface transport, is a genuine and often superior alternative to aviation across most mainland routes.

Where air travel becomes truly important is for expats living in — or making regular trips to — Northern Ireland, the Scottish Highlands and Islands, and other areas with limited surface connections. Nearly all flights to and from Northern Ireland use one of Belfast’s two airports, with 40% of passengers travelling to or from London and 21% to or from Liverpool or Manchester. For expats based in Belfast, frequent and affordable flight connections to the mainland make air travel a practical everyday reality.

For those residing on Scotland’s islands, Loganair’s Highlands and Islands network provides essential lifeline services — for some communities, these flights represent the primary means of reaching healthcare facilities, business centres, and family. Expats considering relocation to Orkney, Shetland, or the Outer Hebrides would be well advised to research local flight timetables carefully as part of their planning process.

For international travel — whether visiting family in a home country, attending business meetings abroad, or taking holidays — the UK’s global connectivity is exceptional. As of February 2026, the UK has flights to 437 airports in 105 different countries, operated by 135 airlines including 29 low-cost carriers. Expats from most parts of the world will find direct or one-stop connections from their nearest UK airport to their country of origin, with London Heathrow offering the broadest selection of long-haul routes.

A notable contrast exists between smaller regional airports and the large national hubs. While major airports such as Manchester, Heathrow, and Gatwick continue to grapple with congestion, high costs, and inconsistent service, smaller airports including Exeter, Liverpool, and London City are often delivering a more streamlined and passenger-friendly experience. Expats fortunate enough to live near a smaller regional airport may well find the overall travel experience considerably less stressful than those who must route through the busiest hubs.

What should expats know about travel insurance and passenger rights when flying in the UK?

The UK operates a well-established statutory framework for air passenger rights known as UK261 — the domestic successor to the EU’s EC261/2004 regulation, which it closely follows in structure. The CAA serves as the national enforcement authority responsible for upholding Assimilated Regulation (EU) No 261/2004 (‘UK261’), which defines what passengers are owed when they experience significant delays or cancellations, or when they are turned away from a flight.

If a flight you have booked is delayed or cancelled, you may be entitled to financial compensation. Under UK law, airlines must pay compensation to passengers in certain defined circumstances — however, the right to compensation applies only in specific situations, not universally.

Should your flight arrive at its destination gate more than three hours late, you may qualify for compensation ranging from £220 for short-haul routes to £520 for long-haul flights. Exceptional circumstances outside the airline’s control — such as severe weather events — remove the obligation to pay. These figures are correct as of 2025; always refer to the CAA’s passenger rights pages for the most current information.

If your flight is cancelled or you are denied boarding and you are waiting for a replacement flight, or if your departure is delayed by at least two hours, the airline is required to provide care and assistance including meals and refreshments. Where a cancellation or delay necessitates an overnight stay, you are entitled to hotel accommodation and transport between the hotel and the airport.

UK261 covers all flights departing from a UK airport, regardless of the airline operating them. For inbound flights from overseas, the regulation applies only to UK-based carriers. This structure broadly mirrors how EU261 functions within EU member states — a useful reference point for expats already familiar with European consumer travel protections. Those accustomed to the more limited compensation framework of the US Department of Transportation’s domestic rules will find UK261 considerably more favourable to the passenger.

The UK CAA offers comprehensive guidance covering every aspect of booking flights — from selecting fares and understanding baggage policies to verifying travel documentation, understanding ATOL protection, and knowing your rights under Section 75. Despite the protections afforded by UK261, travel insurance remains strongly recommended, as the regulation does not address every eventuality. Insurance can cover financial losses arising from flight disruptions, and can also protect against baggage loss or delay by covering the cost of essential replacements. Always scrutinise policy terms carefully, as exclusions vary significantly between providers.

Frequently asked questions: air travel in the UK for expats

Do I need a passport to fly domestically within the UK?

No passport is required for travel on domestic UK flights. It is, however, good practice to carry photographic identification whenever you fly. A national identity card, driving licence, or passport are all accepted by most carriers as valid documentation. Always verify the specific ID requirements of your chosen airline before travelling, as these can vary between operators.

Which is the best London airport for long-haul international flights?

Heathrow is the UK’s foremost international gateway, handling a record 84.5 million passengers in 2025 and serving as the main operating base for both British Airways and Virgin Atlantic, with connections to nearly every region of the globe. For the widest choice of direct long-haul routes, Heathrow is generally the strongest option. Gatwick also offers an expanding range of long-haul leisure services, particularly to the Caribbean, North America, and popular holiday destinations.

Is flying the best way to travel between London and Edinburgh or Glasgow?

That depends on what matters most to you. While the flight itself takes around an hour, accounting for check-in, security, and transfers at both ends typically brings the total journey time to three or four hours. Direct trains on the East Coast Main Line between London and Edinburgh cover the route in approximately 4–4.5 hours from city centre to city centre, with no security procedures involved. For those based close to a major rail terminal, the train is often the more convenient option. That said, flights booked well in advance can be very competitively priced, and for travellers who prioritise speed above all else, air travel remains a popular choice on these corridors.

How do I get compensation if my UK flight is delayed or cancelled?

Under UK261, airlines are legally obliged to pay compensation to passengers in certain circumstances involving delays or cancellations. Your first step should be to submit a claim directly to the airline. If the airline’s response is unsatisfactory, you can escalate your complaint to an approved alternative dispute resolution (ADR) scheme if the airline participates in one, or to the CAA itself. Detailed step-by-step guidance is available at the CAA’s delays and cancellations page.

Are there flights to the Scottish islands, and how reliable are they?

Loganair, the UK’s oldest operating airline, is Scotland-based and specialises in Highlands and Islands services. The carrier links mainland Scotland to destinations including Stornoway, Kirkwall (Orkney), Sumburgh (Shetland), Benbecula, Islay, Tiree, and several others. These routes perform a critical lifeline function but are susceptible to disruption from adverse weather, especially during winter months. Booking in advance is recommended, particularly over school holidays and throughout the summer season.

What booking platforms are most popular for UK domestic flights?

Skyscanner, Google Flights, Kayak, and Expedia are among the most widely used tools for searching and booking domestic UK flights. Booking directly via airline websites — whether easyJet, British Airways, Loganair, Ryanair, or Jet2 — generally offers the greatest transparency on the final price, including baggage and seat selection costs, and gives you the most direct route to customer support if disruption occurs.

Do I need an ETA to fly into the UK if I am not a UK or Irish national?

From 2025, an Electronic Travel Authorisation (ETA) costing £16 is required for most visa-free visitors arriving in the UK from abroad. Expats already living in the UK with valid leave to remain, or those holding settled or pre-settled status under the EU Settlement Scheme, are exempt from this requirement. As immigration rules can change, always verify your individual circumstances using the official GOV.UK visa checker before making any travel arrangements.

Is travel insurance necessary when flying within or to and from the UK?

While the UK261 framework provides meaningful statutory protections covering delays, cancellations, and denied boarding, travel insurance fills the gaps that legislation does not address — such as medical emergencies, trip cancellation prior to departure, lost or delayed baggage, and a range of other unforeseen events. Insurance can help cover financial losses from flight disruptions and provide funds for essential replacement items if baggage is delayed or lost. For expats making international trips back to their home country, travel insurance is particularly advisable. Read any policy carefully before purchasing to make sure it is appropriate for your travel arrangements, paying close attention to exclusions.
