Flexibility is important, which is why we offer free cancellations on the majority of car rentals. If your Six Flags Over Texas plans suddenly change, log in to your account through the
Trips portal, select “manage booking” and then choose “cancel this car.” Flexibility is just the beginning of the reasons to book your wheels with Expedia. Combine your flights, hotel and vehicle into a vacation package and save on your entire escape. And that means more money to spend on whatever your heart desires!
