If you've ever craved a Shake Shack burger on a flight, one airline has you covered. Delta Air Lines is expanding its Shake Shack partnership, the carrier said in a news release on Tuesday, Mar. 4. Shake Shack's burgers will now be available on flights 900 miles and longer that depart

Better than picking up an order of airport Shake Shack to-go and carrying it on board, hot Shack burgers are now served in-flight on select Delta routes.

Delta and Shake Shack have teamed up to serve burgers to some passengers on flights of more than 900 miles out of Atlanta, Los Angeles, New York-LaGuardia and Seattle. But not everyone on board will be able to savor the taste of the burgers. They will only be for those flying in First Class, Delta said in a news release.
