Delta Air Lines will soon serve Shake Shack cheeseburgers to first-class customers on certain flights out of Boston — including to Atlanta.

The first-class meal option will be offered starting Dec. 1 on routes of more than 900 miles out of Boston Logan International Airport. The airline said it “plans for expansion to other U.S. markets throughout 2025.”

The in-flight ShackBurger will be customizable with toppings like tomato, lettuce and ShackSauce and will be served with chips, a Caesar salad and a dark chocolate brownie.

First-class customers will be able to order the Shake Shack cheeseburger in advance through the Delta app or a link in their email up to seven days before departure.

Stephanie Laster, Delta managing director of onboard service, in a written statement called the cheeseburger “an iconic comfort food … and we’re thrilled to elevate the offering with Shake Shack.”

Delta has for years had a partnership with Shake Shack founder Danny Meyer and his Union Square Hospitality Group for in-flight catering on some flights out of New York’s John F. Kennedy International Airport.

New York-based Shake Shack has seven locations in Georgia, including in Alpharetta, Piedmont Park, the Eastside Beltline, Buckhead Village and a location opened in 2018 at Hartsfield-Jackson International Airport.

A Shake Shack with a bar is planned for Battery Atlanta at Truist Park.

In addition to changing its in-flight menu, including the addition of the Shake Shack cheeseburgers, Delta is making other changes to its in-flight service, including replacing plastic cups with paper cups over the next year.
