Delta passengers flying out of Los Angeles will soon be able to enjoy Shake Shack on select flights, as the fast casual chain and the airline announces an expanded partnership.

In November, Delta announced that first class passengers on flights of more than 900 miles out of Boston could pre-select food from the Shake Shack menu for their in-flight meal. Delta said at the time that it would begin expanding that partnership with Shake Shack throughout 2025.

On Tuesday, the airline announced that it has in fact increased the number of cities eligible for the in-flight food option, expanding to Atlanta, Los Angeles, Seattle and New York City’s LaGuardia Airport.

Passengers on eligible flights can pre-select the Shake Shack cheeseburger meal up to 24 hours before their flight online or through the Delta app. The meal features the restaurant’s signature Angus beef patty topped with cheese and served on a toasted potato bun, customized with tomato, lettuce and the restaurant chain’s eponymous ShackSauce on the side.

The meal also comes with a dark chocolate brownie and a Caesar salad, officials said.

Additionally, Delta is celebrating the arrival of Shake Shack on more flights, as well as with the ride-hailing app Uber joining its SkyMiles program this spring.

Delta, Shake Shack and Uber Eats will offer a buy-one, get-one ShackBurger promo on Uber Eats for SkyMiles Members who have signed up to link their Delta and Uber accounts.
