Booking & service notes
Schedules, fares, and aircraft assignments for Delta Air Lines change frequently, sometimes weekly. The data on this page is intended as a stable reference for codes, headquarters, fleet scale, and hub list; for live availability, fare class rules, baggage policies, and seat selection, always consult the carrier's own booking system at www.delta.com. When a flight is operated under Delta Air Lines's code but flown by a regional partner, the operating carrier is normally disclosed on the booking page; this distinction matters for elite-status benefits and, in rare cases, for irregular-operations rebooking.
