Have a flying question?

Denver IS a very large airport, but it is extremely simple to figure out and to get around in, so you won't have a problem. Since you flights are both with United, the gates will be fairly close and you probably won't need to ride the train at all. Gates are assigned very late, so there is no way to anticipate what gate you will arrive at and what gate you depart from. However, toward the end of your flight to Denver the flight attendants will have the gate numbers and be able to tell you how to get from one to the other. There will also be a map in the back of the United magazine, so mark the gates and take it with you -- the airlines encourage you to do that, by the way. You will have plenty of time to switch planes, and really don't need to be worried about it at all! Have a great trip!
