Frequently asked questions

Is it cheaper to buy a plane ticket from Detroit Metro Airport to St. Louis Airport last minute?
Booking your trip from Metro Airport to SUS last minute could save you a nice sum if you luck out and find a terrific deal. However, fares don't typically get cheaper closer to the departure date. If you procrastinate, flights could also be sold out or the best seats gone (because no one wants the middle seat). If you want to be on the safe side, book well ahead of your departure date. 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 fares yet, check back regularly as deals are updated on Expedia constantly.
What airports do you fly into for St. Louis from Detroit?
From Detroit, you can connect to St. Louis through Spirit of St. Louis Airport (SUS), Lambert-St. Louis Intl. Airport (STL) and St. Louis Downtown Airport (CPS). It's a good idea to check which airport is more convenient for you before making your decision. If you choose Spirit of St. Louis Airport (SUS), it's around 40 kilometers west of the downtown area. Use the dollars you save when booking your ticket with Expedia to enjoy the city's popular sights, such as Busch Stadium and Gateway Arch.
Can I change the date of my flight from Metro Airport to Spirit of St. Louis Airport (SUS)?
Quickly make changes to your Detroit Metropolitan Wayne County Airport (DTW) to SUS journey via the Expedia Trips portal. But before you begin, read over the rules and conditions in your itinerary to find out what the carrier will let you do and if any charges apply. Some airlines charge a change fee per person, on top of any difference in fares. But if you booked in the last 24 hours, you may be able to cancel for free and arrange new flights. You can also check out our Customer Service portal to find the answers to your questions and to chat with our Virtual Agent.
