Does it matter which Taipei airport I land at?
Short answer
Yes, pleasantly. Taoyuan is the main international gateway outside the city; Songshan sits inside Taipei itself and handles domestic plus a handful of regional routes.
Two airports, one lucky one
Taoyuan International is where most international flights land — in Taoyuan, outside Taipei, connected to the city by the Airport MRT with its Express and Commuter trains.
Songshan is the rarity among capital airports: it sits inside Taipei City, in Songshan District, and by its own designation is an international airport running both international and domestic sections. If your itinerary lands there, the city is effectively outside the door.
Who actually uses Songshan
Its international side is a short list of regional city-pair routes, while its domestic side is the jumping-off point for Taiwan's outlying islands and east coast. Most long-haul and regional international traffic still means Taoyuan.
The pairing logic mirrors Tokyo and Seoul: the close-in city airport handles the short premium routes, the big one further out handles the world. If you can choose a fare into Songshan, you are buying back an hour of your day.
Reading your booking
The codes are TPE for Taoyuan and TSA for Songshan, and both display as Taipei. As always, the code is the truth and the city name is marketing.
For departures, budget accordingly in reverse: Songshan is a metro ride from most of the city, while Taoyuan means the Airport MRT with the Express-versus-Commuter choice covered in the airport-to-city answer.
Good to know
- TPE and TSA both display as Taipei — check the code
- Songshan is inside the city; a fare into it buys back an hour
By about an hour, yes. Haneda sits inside Tokyo; Narita is in the next prefecture.
Yes. Capital sits inside the city in Chaoyang; Daxing is far to the south with its own separate railway. They are not interchangeable.
Yes. Full-service airlines use Suvarnabhumi; low-cost carriers mostly use Don Mueang, 46km away with no rail link of its own.
More here than almost anywhere. The three international gateways are not alternatives to one another — they are the north, the centre and the south of a country the train needs 36 hours to cross.
Gimpo is far closer to Seoul, but almost every long-haul flight uses Incheon, so you rarely get to choose.
