We know flexibility is important, which is why we offer free cancellations on most car rentals. If your St. Louis Union Station plans change, log in to your account through the
Trips portal, select “manage booking” and “cancel this car.” Flexibility is just the beginning of the benefits of booking your wheels with Expedia. Bundle your flights, accommodations and vehicle into a package deal and you’ll save on your entire escape. And that means more money to spend on sightseeing, food or whatever you like!
