Frequently asked questions

Is it cheaper to buy a plane ticket from Boardman/Polando Field to Lambert Field last minute?
When it's time to book your flights, it's better to be prepared. While you could find a deal on a HYA to Lambert-St. Louis Intl. Airport (STL) 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 travel it's three to four months.
What airports do you fly into for St. Louis from Cape Cod?
Lambert-St. Louis Intl. Airport (STL), Spirit of St. Louis Airport (SUS) and St. Louis Downtown Airport (CPS) are your choices when heading off from Cape Cod to St. Louis. Approximately 19 kilometers northwest of central St. Louis, Lambert-St. Louis Intl. Airport (STL) is the city's main hub. Keep in mind things such as flight arrival and departure times and the distance to your hotel before deciding on an airport.
