Frequently asked questions

Is it cheaper to buy a plane ticket from IAD to PUS last minute?
Being spontaneous is a great way to explore the globe, but it’s not necessarily the wisest way to track down a cheap plane ticket. It’s better to book your Dulles Intl. Airport to Busan Airport trip ahead of time instead of 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. Leave your spontaneous side for when you reach your destination!
What airports do you fly into for South Korea from Sterling?
There are three airports you can fly to when going from Sterling to South Korea: Gimhae Airport (PUS), Ulsan Airport (USN) and Daegu Intl. Airport (TAE).
