Frequently asked questions

Is it cheaper to buy a plane ticket from Philadelphia Intl. Airport (PHL) to SUS last minute?
Being spontaneous is an amazing way to travel the globe, but it's not always the ideal way to land a bargain flight. Consider booking your Philadelphia Intl. Airport (PHL) to SUS trip in advance rather than leaving it until 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 spontaneity for when you reach SUS!
What airports do you fly into for St. Louis from Philadelphia?
From Philadelphia, you can fly into St. Louis through Spirit of St. Louis Airport (SUS), Lambert-St. Louis Intl. Airport (STL) and St. Louis Downtown Airport (CPS). It's wise to check which airport is the right option for you before making your decision. If you choose Spirit of St. Louis Airport (SUS), it's about 40 kilometers west of the center of the city. Use the dollars you save when booking your seat with Expedia to enjoy the city's popular attractions, such as Busch Stadium and Gateway Arch.
