"Shake Shack has partnered with Delta to offer their Cheeseburgers on select flights. Starting December 1, passengers flying first class on Delta flights out of Boston and on routes over 900 miles can pre-select a Shake Shack Cheeseburger as their meal option at least 24 hours in advance. The meal includes a Cheeseburger with 100% Angus beef, cheese, tomato, lettuce, ShackSauce, chips, a Caesar salad, and a dark chocolate brownie." - Tim Newcomb
