Booking your trip from IAH to Lambert-St. Louis Intl. Airport (STL) last minute could save you a pretty penny if you hit the jackpot and find a real bargain. However, fares don't usually get cheaper as the departure date nears. If you wait, flights could also be booked up or the best seats taken (don't get stuck in the middle!). If you want to be on the safe side, book well ahead of the date you want to leave. Note that some of the biggest deals can be found up to a year in advance. If your favorite airline hasn't released its airfares yet, check back regularly as offers are updated on Expedia constantly.

Lambert-St. Louis Intl. Airport (STL), Spirit of St. Louis Airport (SUS) and St. Louis Downtown Airport (CPS) are your options when heading off from Houston to St. Louis. Roughly 19 kilometers northwest of central St. Louis, Lambert-St. Louis Intl. Airport (STL) is the city's main gateway. Consider factors like flight departure and arrival times and the distance to your hotel before choosing your airport. Busch Stadium and Gateway Arch are two terrific attractions to visit when you arrive at your destination.
What are the most popular departure times for flights from IAH to STL?
The most popular departure times for journeys from IAH to Lambert Field are between 8:00 PM - 9:00 PM on United Airlines. Our suggestion is to zoom off in the morning. The earlier you take off, the better your chances of a delay-free flight with lighter air traffic around.
