Delta Air Lines is ending free drinks and snacks on some of its shortest domestic routes in the United States from 19 May, in a move that affects about 450 flights a day. The change covers nearly 9% of the airline’s domestic network.

The policy shift marks a notable change in the carrier’s onboard service on short-haul flights, where passengers have been able to expect complimentary refreshments. Delta has not said in the material provided whether the cut is permanent or whether it will be reversed later.

The move comes as airlines continue to adjust costs and cabin services across their networks. For Delta, the latest change applies only to a portion of its shortest US routes and does not affect the wider domestic operation.

Delta Air Lines has not been quoted in the source material provided, and no reason was given for the decision.

Passengers on affected flights will no longer receive the free snack and beverage service that has been part of the airline’s short-route offering. The company has said the change begins on 19 May and will cover around 450 daily services.

That makes the update one of the most visible service changes on Delta’s domestic schedule this year, even though it affects a relatively small share of total flights. Nearly 9% of the airline’s US domestic operations will be covered by the new policy.

Airlines often use shorter routes to test changes to onboard service because the flights are less complex and the number of passengers affected is easier to manage. For travellers, the practical impact is that a short domestic trip on Delta may now come without the complimentary refreshments previously offered.

The airline’s broader domestic network remains in place, but the change shows how carriers are continuing to refine what is included in a basic ticket. Delta’s latest move applies only to its shortest US routes and starts on 19 May.
