Beginning March 1, Delta Air Lines introduces complimentary meals on some of its longest flights, including transcontinental routes between New York (JFK) and Los Angeles (LAX)/San Francisco (SFO).

The carrier will be the only U.S. carrier to offer complimentary fresh meals on select coast-to-coast routes. Beginning April 24, the airline will expand its service to offer complimentary meals on 10 other domestic markets from Seattle (SEA), New York, Boston (BOS) and Washington, D.C. (DCA).

The enhancement is part of Delta’s ongoing multimillion-dollar investment in on-board customer experience. The upgrade includes main cabin snacks, enhanced blankets, refreshed food-for-purchase options and free in-flight entertainment. The meal program will feature a variety of options for customers depending on the time of flight. The menus will be refreshed often to support the airline’s focus on offering innovative, seasonal and locally sourced food and beverages. Main cabin passengers on long-haul international flights are provided with complimentary beer, wine, spirits and sleep kits.

“We are all about making our Main Cabin experience the best it can be for our customers and offering free, high quality meals is a big part of that experience,” said Allison Ausband, senior vice president, in-flight service, Delta. “When we tested this concept, our customers loved it and appreciated it so we are implementing in our most strategic markets.”

In addition to the main cabin meal service, customers in Delta Comfort Plus will enjoy a pre-arrival snack basket and complimentary beer, wine and spirits.
