 Danny Meyer’s Blue Smoke is traveling all over the world without opening a single new restaurant.
 Since February, Delta Air Lines has been providing meals from the popular barbecue joint in business class from New York to London. Now it’s expanding the service to six additional European cities, including Paris and Amsterdam.

 Some 3,000 meals a week will be made in Blue Smoke’s kitchens and delivered to Delta’s terminal at John F. Kennedy International Airport.

 “We have Blue Smoke and Shake Shack at the airports, and then we started to put it on our airplanes,” said Gail Grimmett , senior vice president of Delta’s New York operations, adding that the aroma of the barbecue dishes persuades many travelers to request Blue Smoke.

 For Blue Smoke, the deal exposes many more people to its brand. However, Managing Partner Mark Maynard-Parisi said, “we entered into this partnership independent of any potential expansion plans.”

 Blue Smoke has two Manhattan locations and a total of three spots in stadiums and at JFK.
