That might have been a special offer or limited time offer. In the past year I have booked a couple of trips and though there is a space to enter your flight number in, during booking (for Magical Express purposes), there is nothing about any inclusion of flights.
I checked a couple months out. I know that flights too far out wont appear and im not looking to book just yet, just trying to see if its something they still offer or if im going to need to book flights separately. Its nice getting it all done in one go. Thanks.
