Taiwan – Air Travel

What is domestic air travel like in Taiwan, and which routes are available?

Taiwan supports a lively domestic aviation network, with aircraft shuttling between the country’s key cities on a daily basis. Flying has come to feel almost as routine as boarding a long-distance bus, and seats fill up quickly during weekends and public holidays. Even so, the overall scale of the network remains modest compared with large nations such as the US or Australia — it is a purposeful, targeted system rather than an expansive one.

Taiwan itself is a remarkably compact territory — roughly comparable in size to the US state of Maryland — and this geography is one of its defining advantages, allowing travellers to reach virtually every corner of the island within a fortnight or less. Taiwan is served by a well-regarded high-speed and conventional rail network, and getting around by bus or private vehicle is also quite practical. Nevertheless, there are situations where a domestic flight is not just convenient but genuinely essential.

The most important driver of domestic aviation is the fact that Taiwan extends beyond a single landmass. Three island groups sit to the west of the main island — Matsu, Kinmen, and Penghu — along with several smaller islands off the southeastern coast of Taitung County. Reaching these places by any means other than air is largely impractical for most travellers.

For those intending to remain on Taiwan’s main island, flying domestically is rarely necessary — with one notable exception. Taitung, the city furthest from Taipei that falls outside the reach of Taiwan’s High-Speed Rail network, can take several hours to reach by conventional train. Depending on a traveller’s schedule and preferences, a short domestic flight may well be a more sensible choice.

Daily Air Corporation is a small specialist carrier concentrating on particular island destinations — it connects Taitung with Orchid Island, while UNI Air is the preferred choice for travellers heading to the islands west of the main island, including Penghu, Matsu, and Kinmen. Most domestic flight times run to under an hour, and service standards are dependable and contemporary, with both carriers having refreshed their fleets in recent years.

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

The two principal domestic carriers in Taiwan are UNI Air and Mandarin Airlines, operating as the domestic arms of EVA Air and China Airlines respectively. This close relationship with the two major international flag carriers lends the domestic market a degree of stability, though it also curtails independent competition across most routes.

Mandarin Airlines connects Taipei with Taichung, Kaohsiung, Taitung, Hualien, Penghu, and Kinmen, while UNI Air serves Taipei, Taichung, Chiayi, Tainan, Kaohsiung, Taitung, Hualien, Penghu, Kinmen, and the Matsu islands. Together, the two airlines cover all commercially significant domestic routes.

UNI Air and Mandarin Airlines collectively account for the entirety of scheduled domestic flights in Taiwan, creating what amounts to a duopoly over both mainland and island routes. Unlike the heavily deregulated domestic markets of the US or the EU, where multiple carriers aggressively compete for passengers, Taiwan’s domestic aviation operates within a regulated fare structure administered by the Civil Aviation Administration (CAA).

In the international arena, China Airlines and EVA Air are Taiwan’s foremost full-service carriers. China Airlines, established in 1959, holds the distinction of being the country’s largest airline and national flag carrier. More recently, boutique carrier Starlux Airlines entered the market with a focus on premium cabin quality, refined in-flight entertainment, and an elevated service experience. On the international budget side, Tigerair Taiwan has been particularly active in short-haul leisure travel, expanding services to numerous Japanese cities and launching seasonal flights to South Korea’s Jeju Island. Tigerair Taiwan, however, operates exclusively on international routes — no pure low-cost carrier currently offers scheduled domestic flights within Taiwan.

Both UNI Air and Mandarin Airlines operate under CAA oversight, with the aviation authority establishing upper and lower fare limits for domestic routes based on 14 cost categories submitted by the carriers. This regulatory model keeps ticket prices relatively stable, though both airlines have lobbied the CAA to revise fare bands in response to rising operating costs.

How do you book domestic flights in Taiwan?

Securing a domestic flight in Taiwan is a simple process, and travellers have several options for doing so. The most direct approach is to book through the airlines’ own websites — both UNI Air and Mandarin Airlines offer fully functional online booking platforms in both Chinese and English.

International third-party platforms such as Skyscanner, Expedia, and Baolau also index Taiwan’s domestic flights and enable price and availability comparisons. Residents who prefer local options can also book through Taiwanese travel agencies or via the ubiquitous convenience store kiosks — a distinctively Taiwanese feature of everyday commerce.

Because seats frequently sell out on weekends and public holidays, booking ahead is strongly advisable. Travel agencies can also handle reservations on your behalf. Last-minute seats are genuinely scarce during high-demand periods — particularly around Chinese New Year (Lunar New Year), the Dragon Boat Festival, and the summer holiday months — so planning well in advance is especially important for island routes such as Penghu and Kinmen.

Under the Standard Contract for Passenger Transit in Domestic Flights, drawn up by the Civil Aeronautics Administration (CAA) of the Ministry of Transportation and Communications, tickets for flights during three-day or longer legal holidays are “valid on date/flight shown only and rendered invalid thereafter.” Always review fare conditions carefully before completing a booking, particularly during public holiday periods.

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

Taiwan’s domestic ticket prices are governed by fare bands established by the Civil Aviation Administration, which makes costs fairly predictable and reasonably accessible — though they are far from bargain-basement. On popular routes such as Taipei–Penghu or Taipei–Kinmen, economy class fares generally begin at around NTD 1,000–1,500 (roughly USD 30–50) one way when purchased in advance, though these prices climb considerably during peak travel periods. Always check the latest pricing directly on the UNI Air or Mandarin Airlines websites, as fares are subject to frequent revision.

UNI Air has pointed out that the domestic fare adjustment mechanism has not been updated in 26 years, and while ticket prices can be modified through fuel surcharge adjustments, the remaining 13 cost categories have remained unchanged throughout that period. As of late 2025, both carriers have formally requested a comprehensive fare review from the CAA, which could bring modest increases; it is worth checking current fares before making travel arrangements.

Airfares across all 23 domestic routes are eligible for adjustment, with recent revisions falling in a range of 2.7% to 6.9% to account for fuel cost fluctuations. This fuel-linked mechanism means fares can shift with relatively little notice. Unlike some international markets where dynamic pricing produces extreme variation in ticket costs, Taiwan’s regulated structure means that the gap between the lowest and highest fares on any given domestic route tends to remain fairly narrow.

Baggage allowances on domestic services are more limited than on international flights: passengers are entitled to check in up to 10 kg of luggage free of charge domestically, compared with 23 kg on international routes. If you are travelling with more than a small bag, you should factor in the potential for excess baggage fees. Verify current allowances directly with the airline prior to departure, as policies may be updated at any time.

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

Taiwan has four international airports: Taoyuan International Airport, Kaohsiung International Airport, Taichung International Airport, and Taipei Songshan Airport. For the overwhelming majority of expats arriving from overseas, Taoyuan will serve as the principal point of entry.

Situated in Taoyuan City, roughly 40 kilometres from central Taipei, Taoyuan Airport is Taiwan’s largest international facility and functions as the main hub for most international air services. It offers connections to destinations across Asia, North America, Europe, Oceania, and the Middle East, with the greatest number of links concentrated within Asia. The airport processes approximately 48 million passengers annually.

Taoyuan Airport currently operates two main terminals, T1 and T2, with a third terminal under active construction. The airport is served by 50 international carriers flying to and from 103 destinations. It also serves as the primary base for Taiwan’s two flagship carriers, making Taoyuan a key node within both the Star Alliance and SkyTeam global networks.

Travelling from Taoyuan Airport into Taipei is highly convenient. The airport is integrated with Taipei’s mass transit system via the Taoyuan Airport MRT, which delivers passengers to Taipei Main Station — a major interchange for the High-Speed Rail, conventional railways, buses, and intercity coaches. The one-way MRT fare between Taoyuan Airport and Taipei Main Station is NTD 160 as of 2025, placing it among the most affordable international airport rail links anywhere in the world.

Kaohsiung International Airport (KHH) serves Taiwan’s second-largest city and the broader southern region. It receives international flights from a range of Asian destinations and provides a quieter alternative to Taoyuan for those relocating to southern Taiwan. Kaohsiung Airport is directly connected to the city’s metro network, making it highly convenient for new arrivals in the south.

Taipei Songshan Airport (TSA) is located within the city of Taipei itself and handles a mix of regional international services — particularly to Tokyo Haneda, Seoul Gimpo, and Shanghai — as well as domestic flights. It is especially useful for expats residing in central Taipei who prefer to avoid the longer journey out to Taoyuan. Taichung International Airport (RMQ) serves central Taiwan with a more limited selection of regional connections; unlike several other Taiwan airports, it is not linked to the metro system, with taxis and buses being the main transport options.

Are there any rules, restrictions, or practicalities at Taiwan’s airports expats should know?

For domestic travel, identification requirements are clearly defined: Taiwanese nationals check in using their national identity card, while foreign nationals are required to present their passport. Unlike some countries where a driving licence or residency card is sufficient for internal flights, foreign residents in Taiwan must carry their passport whenever flying domestically.

For international arrivals, Taiwan has made significant updates to its immigration procedures. The Taiwan National Immigration Agency confirmed that the paper arrival card would be fully discontinued from 1 October 2025, requiring visitors to fill in the arrival card digitally before travelling — this can be done up to three days prior to arrival. The online form is accessible through the Taiwan National Immigration Agency website and takes only a few minutes to complete.

Taiwan also provides e-Gate automated immigration facilities for qualifying travellers. These automated lanes are installed at major airports and allow eligible passengers to clear immigration without visiting a staffed counter; however, first-time users cannot access the e-Gates immediately and must register on their initial entry. Registration takes place at a dedicated counter, involves recording your fingerprints and photograph, and is completed in just a few minutes. Once enrolled, you can pass through the e-Gates swiftly on all subsequent visits.

Customs regulations deserve careful attention. Travellers must declare cash amounts exceeding NTD 100,000, foreign currencies above USD 10,000, or more than CNY 20,000. Duty-free allowances as of November 2025 include 200 cigarettes (one carton), up to one litre of alcohol, and cash not exceeding NTD 100,000. Taiwan enforces rigorous biosecurity controls; travellers from certain countries may be subject to agricultural inspection, and failing to declare fresh produce, meat, or plant materials can result in substantial fines. Always consult the latest regulations on the Customs Administration of the Ministry of Finance website before travelling.

Regarding check-in times, Taoyuan recommends arriving at least two to three hours before international departures. Domestic check-in tends to move more quickly, but arriving 45 to 60 minutes before departure is advisable, particularly on busy island routes at weekends.

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

For most expats based in Taiwan’s main urban centres — Taipei, Taichung, Tainan, or Kaohsiung — domestic air travel is unlikely to feature regularly in everyday life. Taiwan’s high-speed and conventional rail networks are well-developed, and road travel by bus or private vehicle is equally practical. The High-Speed Rail (HSR) links the western corridor from Taipei to Kaohsiung in approximately 90 minutes, making it the go-to choice for intercity journeys on the main island.

Where air travel becomes a genuine necessity is for those who live on or frequently travel to the outlying islands. Kinmen sits geographically closer to the Chinese city of Xiamen than to Taiwan proper, making it one of the most distant destinations within Taiwan’s jurisdiction. Penghu, positioned between the main island and the Chinese mainland, draws large numbers of visitors and sees many residents and their families travelling back and forth by air on a regular basis.

For expats flying back to their countries of origin, Taiwan’s international connectivity is robust and continues to strengthen. In recent years, Taiwan’s aviation market has attracted a steady stream of new route announcements from both local and foreign carriers. China Airlines confirmed a new Taipei–Phoenix service scheduled to begin in December 2025, while EVA Air announced plans to launch a Taipei–Dallas/Fort Worth route from October 2025. The Hong Kong–Taipei corridor was the world’s busiest international route in 2024, recording 6.8 million seats and a 48% expansion in capacity. This depth of connectivity gives expats ample choice for both regional and long-haul travel.

Expats residing in Taipei should be aware that Taoyuan International Airport, as Taiwan’s gateway to the world, ranks among Asia’s busiest airports by international passenger and cargo volume. The airport’s extensive network of connections to major global hubs means that returning home — whether for annual leave, family visits, or professional commitments — is comparatively straightforward when set against more geographically remote postings elsewhere in the Asia-Pacific.

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

Taiwan does not operate a passenger rights framework directly analogous to the European Union’s EU Regulation 261/2004 — which prescribes standardised compensation for flight delays, cancellations, and denied boarding — or the US Department of Transportation’s (DOT) equivalent rules. Passenger rights for domestic flights in Taiwan are instead governed by the Standard Contract for Domestic Civil Air Transport Services, administered by the Civil Aviation Administration (CAA) under the Ministry of Transportation and Communications. This contract establishes the terms for refunds, rebooking, and airline liability, though the compensation provisions are less prescriptive than those found under EU rules.

For domestic flights, refund service fees during peak holiday periods follow a tiered structure: 10% if a booking is cancelled seven or more days before departure, 20% for cancellations made one to six days before the flight, and 30% if cancelled on the day of departure prior to the scheduled time. Tickets abandoned after the flight has departed are generally non-refundable, so reading the fare conditions carefully at the time of booking is essential.

On international routes, the applicable rights will depend on both the airline and the specific route. Carriers registered in EU member states or flights departing from EU airports are subject to EU Regulation 261/2004; flights operated by Taiwanese airlines departing from Taiwan are not. Many of Taiwan’s carriers — including China Airlines and EVA Air — maintain their own service standards for handling delays and cancellations that broadly mirror industry norms, though the level of protection varies. Reviewing the conditions of carriage for your specific airline and itinerary before flying is always a sound approach.

Travel insurance is highly recommended for all expats living in Taiwan, with particular emphasis on medical evacuation, trip interruption, and baggage protection. Securing a comprehensive policy before any trip is strongly advised; discuss evacuation assistance, medical coverage, and trip cancellation provisions with your insurer. It is especially important to select a policy that addresses typhoon-related disruption — Taiwan’s Central Weather Bureau records an average of five typhoon warnings each year, with three to four storms typically making landfall, often causing major airport closures and widespread flight cancellations.

Frequently asked questions

Do I need my passport to take a domestic flight in Taiwan as a foreign resident?

Yes. Foreign nationals are required to produce their passport when checking in for domestic flights in Taiwan. Taiwanese citizens use their national identity card for this purpose, but foreign residents — including those holding an ARC (Alien Resident Certificate) — must carry their passport for any domestic air travel.

How far in advance should I book domestic flights in Taiwan?

Because seats fill up quickly on weekends and public holidays, booking well ahead of your intended travel date is strongly advisable. For routes to Penghu, Kinmen, and Matsu — especially during Chinese New Year or the summer holiday season — reserving your seat several weeks in advance is highly recommended. During quieter periods on the main island, shorter booking lead times are generally sufficient.

Is flying the best way to get between Taipei and Kaohsiung?

For the majority of travellers, the Taiwan High-Speed Rail (HSR) is a more practical choice than flying between Taipei and Kaohsiung. The HSR completes the journey in roughly 90 minutes, runs at high frequency, and compares very favourably with air travel on a door-to-door basis once airport transit time is taken into account. Taiwan’s broader rail network and bus services also make surface travel a highly viable option.

Which airlines fly nonstop from Taiwan to North America?

Five airlines operate nonstop services between Taiwan and the US: China Airlines, EVA Air, Delta Air Lines, Starlux Airlines, and United Airlines. China Airlines and EVA Air offer the broadest coverage, flying from six US cities including Chicago, Houston, Los Angeles, New York, San Francisco, and Seattle. EVA Air’s North American network also reaches nine passenger gateways, including Toronto and Vancouver.

How do I get from Taoyuan Airport to central Taipei?

Taoyuan Airport lies approximately 40 kilometres from central Taipei and is well connected to the city via the Taoyuan Airport MRT, which reaches Taipei Main Station in around 35 minutes. The one-way MRT fare is NTD 160 as of 2025. Taxis and pre-arranged private transfers are also readily available from both terminals.

Do I need to complete a Taiwan arrival card when I move there?

The paper Taiwan arrival card was discontinued as of 1 October 2025, and all visitors are now required to complete the arrival card digitally before travelling — the form can be submitted up to three days before arrival. It is available through the Taiwan National Immigration Agency website and takes only a few minutes to fill in. Most foreign nationals must complete it upon every entry into Taiwan.

Are there low-cost carriers for flying within Taiwan?

At present, no low-cost carriers operate scheduled domestic flights within Taiwan. The domestic market is served solely by UNI Air and Mandarin Airlines — along with Daily Air Corporation on certain island-specific routes — all of which operate within fare bands regulated by the CAA. Budget airlines have expanded significantly in the short-haul international leisure space, but this has not extended to the domestic network. Fares are generally reasonable, though travellers should not expect the ultra-low prices associated with LCC-dominated domestic markets elsewhere in Asia.

What are Taiwan’s customs rules when arriving from abroad?

As of November 2025, duty-free allowances cover 200 cigarettes (one carton), up to one litre of alcohol, and cash not exceeding NTD 100,000. Any cash above NTD 100,000, foreign currencies exceeding USD 10,000, or more than CNY 20,000 must be formally declared. Taiwan also applies strict biosecurity rules to food and agricultural products brought into the country. For the most up-to-date information, consult the Customs Administration of the Ministry of Finance ahead of your arrival.
