Frequently asked questions

Is it cheaper to buy a plane ticket from BUF to St. Louis Airport last minute?
When it's time to book your flights, it's always better to be prepared. While you could pick up a deal on a Buffalo Niagara Intl. Airport (BUF) to Spirit of St. Louis Airport (SUS) flight at the last minute, fares usually don't get cheaper as the departure date nears. Based on flight pricing and demand studies in 2022, we have found that the sweet spot to lock in a domestic flight is between 28 – 35 days in advance. For international trips it's between three and four months.
What airports do you fly into for St. Louis from Buffalo?
Spirit of St. Louis Airport (SUS), Lambert-St. Louis Intl. Airport (STL) and St. Louis Downtown Airport (CPS) are your choices when taking off from Buffalo to St. Louis. Approximately 40 kilometers west of downtown St. Louis, Spirit of St. Louis Airport (SUS) is the city's major gateway. Take into account factors such as flight schedules and the distance to your hotel before deciding where you fly into. Busch Stadium and Gateway Arch are a couple of top attractions to check out when you arrive at your destination.
Can I change the date of my flight from BUF to St. Louis Airport?
Make changes quickly to your Buffalo Niagara International Airport to St. Louis Airport journey via the Expedia Trips portal. Before making any amendments, read through the rules in your itinerary to find out what you're able to do and if fees apply.
