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

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.

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.
