Hello, Joan!
Not to worry!
Disney's Magical Express is tied to your resort reservation, regardless of the airline with whom you choose to fly to Orlando International Airport.
As long as you have a reservation number, that's all you need to arrange for your Magical Express transportation to and from the airport. Either ask your travel agent to assist you with this, or enter your reservation information online at
Walt Disney World.com. There, you can click on "My Disney Vacation" and "My Reservations" in order to login / sign up for access to tools such as online check-in which will enable you to inform Disney of your flight information, among other things. If unsure, ask your travel agent to assist you.
Now, as you plan your 2013 trip, please be sure to come back to the Walt Disney World Moms Panel and ask as many questions as you can! We've got Moms who can advise you on your cruise, Moms who can advise you on your stay at Disney's Port Orleans Resort, Moms who can advise you on dining options...and some of those Moms are even DADS! All in all, we love to help!
