Eligible travelers can choose their entrée up to seven days prior to departure using the Fly Delta app or a link emailed to their email.
Along with chips, a Caesar salad, and a dark chocolate brownie “reminiscent of Shack Attack flavors from some of the brand’s dessert offerings.”
Other toppings including tomato, lettuce, and Shake Shack’s well-known ShackSauce will be served on the side.
The popular Shake Shack menu staples, such its milkshakes, hot dogs, and crinkle-cut fries, will not be available.
