Apple's Passbook app is gaining more and more support, where just recently we saw huge brands like Major League Baseball, Ticketmaster and Walgreens all jump on the iOS 6 app. But, Passbook has just received some other high-profile brand support.

McDonald's, Airbnb and Eventbrite have all jumped on-board. The Passbook-enabled McDonald's app can be used to order and purchase food directly from your iPhone, but is only available in France at the moment unfortunately. Airbnb and Eventbrite are useful additions to the ever-growing support of Passbook.

Eventbrite have issued out over 50 million tickets, racking up over $1 billion in sales, with Airbnb booking more than 10 million guests as well as seeing a 26% rise in mobile traffic. Both of these companies deal with mobile transactions more than McDonalds, but the more support Passbook gets, the better the app will become.
