Frequently asked questions

Is it cheaper to buy a plane ticket from Sea-Tac Airport to Tainan Airport last minute?
Being the spontaneous type is an amazing way to discover the world, but it's not necessarily the best method to grab a cheap flight. It's better to book your Sea-Tac Airport to Tainan Airport trip well in advance rather than leaving it to the last minute. Based on flight pricing and demand studies in 2022, we have found that the best time to book domestic flights is between 28 – 35 days ahead of the departure date, and international flights three to four months in advance. We recommend saving that spontaneity for when you get to your destination!

From Seattle, you can connect to Tainan through Tainan Airport (TNN), Kaohsiung Intl. Airport (KHH) and Penghu Airport (MZG).
