Delta Air Lines (DL)

Delta Air Lines (DL/DAL) is a full-service network airline based in United States, founded in 1925. It operates from its hub at JFK, where much of its connecting network is built.

It is a member of SkyTeam, one of the major global airline alliances, so its frequent-flyer program and network connect with other SkyTeam carriers — useful when you need a through-ticket or want to earn and use miles across partner airlines.

As a full-service carrier, its fares generally bundle more into the base ticket than a budget airline, but the exact baggage allowance, seat selection and change rules still depend on the fare type you pick, so confirm the conditions of your specific fare before you pay.

When flying Delta Air Lines, book under the airline code DL, check the carrier's current baggage, check-in and travel-document rules on its own website, and allow enough time at JFK if you are connecting.
