Frequently asked questions

Is it cheaper to buy a plane ticket from Pittsburgh Intl. Airport (PIT) to SUS last minute?
Being spontaneous is an amazing way to travel, but it's not always the best method to find a bargain fare. Consider booking your Pittsburgh Airport to St. Louis Airport trip in advance instead of 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. We recommend saving that spontaneity for when you get to St. Louis Airport!

From Pittsburgh, you can connect to St. Louis through Spirit of St. Louis Airport (SUS), Lambert-St. Louis Intl. Airport (STL) and St. Louis Downtown Airport (CPS).
