Frequently asked questions

Is it cheaper to buy a plane ticket from LAS to St. Louis Downtown Airport last minute?
Booking your flight from McCarran Intl. Airport (LAS) to St. Louis Downtown Airport at the last minute could save you a pretty penny if you strike it lucky and find a real steal. However, tickets typically don't come down in price as the date of departure nears. If you wait around, flights could also be sold out or the best seats gone (that could mean the middle seat!). If you don't want to hedge your bets, book well ahead of the date you want to leave. It's worth noting that some of the best deals can be found up to 12 months in advance. If your favorite airline hasn't released its fares yet, check back regularly as deals are updated on Expedia all the time.

St. Louis Downtown Airport (CPS), Lambert-St. Louis Intl. Airport (STL) and MidAmerica-St. Louis Airport (BLV) are your choices when traveling from Las Vegas to East St. Louis. Roughly 3 kilometers south of central East St. Louis, St. Louis Downtown Airport (CPS) is the city's principal hub. Keep in mind things like flight arrival and departure times and the distance to your hotel before settling on an airport.
