T4X, Delta’s pop-up space at 376 West Broadway at Broome Street, will be offering on May 19 through May 22 a free “burger pass” for a complimentary Shake Shack Burger, according to Serious Eats.
Delta set up T4X this month to highlight the new John F. Kennedy International Airport’s Terminal 4, which will include a Shake Shack. The actual airport terminal opens Friday, May 24. T4X is open Tuesdays through Sundays 11 a.m. to 3 p.m. until May 22. While you’re there, Delta has $4 lunch boxes representing the airline’s international destinations.
