Love Shake Shack? You can enjoy it on Delta if you’re flying out of these cities

If you’ve been waiting to enjoy Shake Shack during first-class flights on Delta, you may be in luck– the gourmet burger chain and airline have expanded their partnership.

Last year, Shake Shack and Delta announced passengers taking first-class flights out of Boston on routes of 900 miles or more could pre-select a Shake Shack cheeseburger as their lunch or dinner option.

Now, Delta has expanded that perk to first-class flights over 900 miles out of Atlanta, Los Angeles, New York-LaGuardia and Seattle.

“Our partnership with Delta has been a truly fantastic way to bring Shake Shack to even more guests in a setting where hospitality truly matters – while traveling,” said Michael Kark, the President of Global Licensing at Shake Shack, in a press release. “The response has been incredible, and we’re thrilled to expand this partnership, giving even more Delta travelers the chance to enjoy Shake Shack along their journey.”

Delta’s Shake Shack cheeseburger meal features a 100% Angus beef patty, topped with cheese and served on a toasted potato bun. Passengers can customize their burgers with toppings including tomato, lettuce and Shake Shack’s famous ShackSauce. The meal also features chips, a Caesar salad, and a dark chocolate brownie.
