Frequently asked questions

Is it cheaper to buy a plane ticket from BUF to STL last minute?
Being a spontaneous soul is a great way to explore the world, but it's not necessarily the ideal way to track down a cheap plane ticket. It's better to book your BUF to STL trip in advance rather than waiting till 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. Save all that spontaneity for when you arrive in STL!
