If you’re excited about New York’s newest Shake Shack, which opens May 24 at Terminal T4 at JFK Airport, you might want to stop by Delta’s T4X Soho pop-up at 376 West Broadway in Soho between Sunday May 19 and Wednesday May 22. From 11 a.m. to 3 p.m. each day — and certainly while supplies last — visitors can pick up a boarding-pass-like voucher that entitles the bearer to one free ShackBurger at any participating Shake Shack, and not just the new one in the airport.
