Frequently asked questions

Is it cheaper to buy a plane ticket from PDX to XLS last minute?
Booking your trip from Portland Airport to XLS last minute could save you money if you get lucky and find a real bargain. However, airfares usually don't get cheaper as the departure date nears. If you hold off, flights could also be booked up or the best seats taken (we hope you like the middle seat!). If you want to be on the safe side, 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 carrier hasn't released its airfares yet, check back regularly as deals are updated on Expedia all the time.
What airports do you fly into for St. Louis from Portland?
There are two options when journeying from Portland to St. Louis — St. Louis (XLS) and Richard-Toll (RDT). If you choose St. Louis (XLS) you'll be approximately 3 kilometers northeast of central St. Louis. Check in to your hotel, then head out and take in your surroundings. Faidherbe Bridge and Parc National de la Langue de Barbarie are just a couple of this city's favorite attractions.
