Delta will introduce new main cabin service in November. It will feature complimentary welcome cocktails, featuring Bellinis  to start, a hot towel service and mix-and-match option starters and mains. “This is about investing in every single customer who chooses Delta, no matter where they sit on the plane,” said Allison Ausband, Delta senior vice president, in-flight service. The experience has been refined over the past year through rigorous testing of the service through nearly 14,000 hours of flight time, feedback from more than 1,800 customer surveys, crew feedback and input from a design team made up of 24 flight attendants. Also, in addition to recently upgraded amenity kits, more international onboard enhancements are coming soon — including refreshed ear buds and headsets.
