My guess is that is was not the official Disney website. Also, I assume you mean DME (Disney's Magical Express), not
MDE (My Disney Experience). The Internet provides all sorts of obsolete information. Even the WDWinfo (same company as DISboards) page about DME (
http://www.wdwinfo.com/transportation/magical-express.htm) is hopelessly filled with obsolete information, including all such gems as "Guests flying United Airlines who use the Resort Check-In are currently exempt from the airline's checked bag fee. (This is subject to change at any time.)." Yes that changed -- many years ago. When Resort Airline Check-In (RAC) began in 2005, all participating airlines at the time allowed two free checked bags. Then some airlines began to charge for the second bag. RAC could not handle payment for a second bag. Then most airlines began to charge for all checked bags, so RAC updated its system and processes to allow guests to pay.
