US-based legacy carrier Delta Air Lineshas announced that it will be expanding its partnership with American fast-food chain Shake Shack, as it will be offering first-class passengers the option to pre-select a Shake Shack cheeseburger meal on select flights out of Los Angeles International Airport (LAX).

The move comes on the heels of a December initial launch out of Boston after the airline served more than 10,000 burgers in the air, Delta said.

This technically isn’t the first time you’ve been able to tote a Shake Shack burger onboard a Delta flight in L.A.: In 2017, Shake Shack opened a location inside Terminal 3—and it even served breakfast—though that outpost appears to have shuttered sometime around late 2020.

Beginning today, first-class passengers on flights with a distance longer than 900 miles going out of New York-La Guardia (LGA), Atlanta (ATL), Los Angeles (LAX), and Seattle will have Shake Shack as an option.

Beginning Tuesday, Delta is serving Shake Shack cheeseburgers to first-class customers on flights over 900 miles that depart from Hartsfield-Jackson Atlanta International Airport, Los Angeles International Airport, New York City's LaGuardia Airport and Seattle-Tacoma International Airport.
