Ever wanted to enjoy a Shake Shack burger at 30,000 feet? Here’s your chance. Well, aside from all the airport locations that Shake Shack has, but no matter.

In honor of National Cheeseburger Day, Delta Air Lines will offer Shake Shack burgers to its Delta One business class customers on "select flights" from JFK to LAX on Sunday, September 18th. On top of that, all flyers between JFK and LAX on that day will get a coupon for a free ShackBurger at the LA West Hollywood Shake Shack.

The Delta / Shake Shack hookup is part of a larger partnership between the airline and Danny Meyer’s Union Square Hospitality Group which creates many of the in-flight menus for Delta One business class flights. Meyer also founded Shake Shack.

No word on if Shake Shack Concretes will be served onboard for National Frozen Custard Day (August 8th, if you were wondering).
