Frequently asked questions

Is it cheaper to buy a plane ticket from STL to Greater Rochester Intl. Airport (ROC) last minute?
Booking your trip from Lambert-St. Louis Intl. Airport (STL) to Greater Rochester Intl. Airport last minute could save you dollars if you happen to find a real steal. However, tickets don’t usually get cheaper closer to the departure date. If you hold off, flights could also be booked out or the best seats taken (don’t get stuck in the middle!). If you’d rather not hedge your bets, book well in advance of when you want to leave. Keep in mind that some of the best deals can be found up to 12 months in advance. If your preferred airline hasn’t released tickets yet, check back regularly as deals are constantly updated on Expedia.

St. Louis to Rochester flights touch down at Greater Rochester Intl. Airport (ROC). Unpack your bags at your hotel and then head out to explore some of the city’s noteworthy attractions, such as Genesee River’s High Falls and University of Rochester. The airport is around 3 mi southwest of the center of Rochester.
