Frequently asked questions

Is it cheaper to buy a plane ticket from William P. Hobby Airport to Dulles Intl. Airport last minute?
Being the spontaneous type is an amazing way to discover the world, but it's not necessarily the wisest method to grab a cheap airfare. Consider booking your HOU to IAD trip 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 arrive at your destination!
