Frequently asked questions

Is it cheaper to buy a plane ticket from SAT to CPS last minute?
Booking your flight from San Antonio Airport to St. Louis Downtown Airport at the last minute could save you cash if you happen to find a real bargain. However, airfares usually don't get cheaper as the departure date nears. If you wait, flights could also be sold out or the best seats gone (because no one wants the middle seat). If you don't want to hedge your bets, book well in advance of your departure date. Keep in mind that some of the best deals can be found up to 12 months in advance. If your favorite airline hasn't released tickets yet, check back regularly as offers are updated on Expedia constantly.
