Delta Air Lines will end food and beverage service on roughly 450 short-haul flights beginning May 19. The change applies to U.S. routes under 349 miles, meaning passengers in main cabin will no longer receive meals, snacks, or drinks on these flights.

The adjustment is expected to affect about 450 daily departures, including short routes such as Los Angeles to San Francisco. The airline noted that the change does not apply to first-class passengers, who will continue to receive in-flight service.
