Frequently asked questions

Is it cheaper to buy a plane ticket from Lambert-St. Louis Intl. Airport (STL) to MTH last minute?
Booking your trip from Lambert-St. Louis Intl. Airport (STL) to MTH at the last minute could save you a pretty penny if you're lucky to find a good deal. However, tickets usually don't come down in price closer to the departure date. If you hold off, flights could also be sold out or the best seats taken. If you don't want to hedge your bets, book well ahead of your departure date. Remember that some of the most awesome deals can be found up to a year in advance. If your preferred carrier hasn't released its airfares yet, check back regularly as offers are constantly updated on Expedia.
Can I change the date of my flight from STL to MTH?

To start, access your STL to MTH itinerary through the Expedia Trips portal and look up the ticket rules about what sorts of changes are allowed.
