Frequently asked questions

Is it cheaper to buy a plane ticket from SLU to BWI Airport last minute?
Booking your journey from SLU to BWI Airport last minute could save you a tidy sum if you happen to find a real bargain. However, tickets usually don't come down in price as the departure date nears. If you procrastinate, flights could also be booked solid or the best seats taken (because who wants the middle seat?). If you'd rather err on the side of caution, book well ahead of the date you want to leave. In fact, you can find some of the biggest deals up to 12 months in advance. If your favorite carrier hasn't released its airfares yet, check back regularly as offers are constantly updated on Expedia.
