Delta Air Lines fleet
The Delta Air Lines fleet comprised 1,004 mainline aircraft and 325 aircraft operated by Delta Connection regional carriers at 30 June 2026. The 1,329-aircraft operating population ranged from 45-seat regional jets to Airbus A350-900 long-haul aircraft. Delta also held purchase commitments for 332 mainline aircraft, while aircraft on order were excluded from the operating fleet until entry into service.[1]
Scope and counting method
Delta reports its mainline aircraft separately from aircraft flown on its behalf under Delta Connection capacity-purchase agreements. The mainline count includes aircraft owned by Delta and held under finance or operating leases. The regional table includes aircraft flown by Endeavor Air, SkyWest Airlines and Republic Airways, regardless of whether Delta or the operating carrier owns or leases the airframe.[1]
At the snapshot date, Delta owned 202 of the regional aircraft and held operating leases on three; the remaining 120 were owned or leased by SkyWest or Republic. Endeavor is Delta's wholly owned regional subsidiary. These distinctions matter because operator, owner and brand are not interchangeable aircraft attributes.[1]
The combined 1,329-aircraft total is a calculated sum of the filing's 1,004 mainline and 325 regional operating totals. It excludes future orders and does not establish daily serviceability for every aircraft.

| Operating total | 893 | 24 | 87 | 1,004 | 15.0 | 332 | 126 |
The commitment total also includes twenty A350-1000s, 100 Boeing 737-10s and thirty Boeing 787-10s, none of which was recorded as an operating subtype. They therefore appear in the order section rather than as zero-count current-fleet rows.[1]
Narrow-body fleet
Delta's mainline narrow-body operation covers several generations. The Airbus side includes the A220, A319, A320, A321ceo and A321neo; the Boeing side includes the 717, 737-800, 737-900ER and 757. This breadth supplies capacity from the smaller A220 and 717 through the long-bodied A321 and 757-300.[1][2]
The A321neo is the principal current narrow-body growth type, with 99 operating aircraft and ninety purchase commitments at 30 June 2026. Delta exercised options for 34 additional aircraft during the March 2026 quarter; deliveries from that order are scheduled to begin in 2029. The filing also records 36 remaining options.[1]
The A220-300 had 58 commitments. By contrast, the 737-10 had one hundred commitments and thirty options but no operating aircraft. It is not counted as a present Delta type or connected as an operating relationship before entry into service.[1]
Older subfleets remain substantial. The A320-200, 717, 737-800, 757-200 and 757-300 all had average ages above 23 years. Average age describes a subtype population and must not be used as an individual aircraft's age.[1]
Wide-body fleet
Delta's operating wide-body fleet is entirely Airbus at the snapshot date: 42 A330ceos, 39 A330-900neos, 41 A350-900s, 58 767s across two subtypes, and no operating 787. The A350-900 is the largest of the newer long-haul subfleets and includes both owned and leased aircraft.[1]
The A330-900neo and A350-900 provide current-generation long-haul capacity, while the A330-200, A330-300, 767-300ER and 767-400ER represent earlier generations. Delta's aircraft guide publishes cabin and seat-map variants separately; a fleet count does not by itself identify the layout assigned to a registration or flight.[2]
In January 2026, Delta announced an additional order for sixteen A330-900s and fifteen A350-900s, with deliveries planned from 2029. The June filing recorded sixteen A330-900neo commitments and eighteen A350-900 commitments in total.[3][1]
Delta Connection fleet
| Operating carrier | CRJ700 | CRJ900 | Embraer 170 | Embraer 175 | Total |
| Endeavor Air | 18 | 127 | — | — | 145 |
| SkyWest Airlines | 2 | 34 | — | 87 | 123 |
| Republic Airways | — | — | 11 | 46 | 57 |
| Total | 20 | 161 | 11 | 133 | 325 |
Endeavor operated the entire 127-aircraft CRJ900 subfleet assigned to it and eighteen CRJ700s. SkyWest operated CRJ700s, CRJ900s and E175s, while Republic operated E170s and E175s. The aircraft carried Delta Connection branding and supported Delta's network, but the operating-carrier field should remain attached to the certificated carrier rather than being replaced by the marketing brand.[1]
Delta's public aircraft guide includes CRJ550, CRJ700 and CRJ900 material, while the SEC fleet table classifies twenty aircraft as CRJ700 and does not publish a separate CRJ550 count. The filing's taxonomy is retained rather than deriving a new subtype split from seat maps.[1][2]
Orders and future types
The 332-aircraft purchase commitment comprised 58 A220-300s, ninety A321neos, sixteen A330-900neos, eighteen A350-900s, twenty A350-1000s, one hundred 737-10s and thirty 787-10s. Delta also held 126 options: 36 A321neos, fifteen A330-900neos, five A350-900s, ten A350-1000s, thirty 737-10s and thirty 787-10s.[1]
Delta ordered thirty 787-10s in the March 2026 quarter, with scheduled deliveries beginning in 2031. In the same quarter it contracted for the additional Airbus wide-bodies and exercised A321neo options. The filing warns that timing remains uncertain because of manufacturing, supply-chain and regulatory constraints.[1]
Orders and options are shown independently. An option is not a firm purchase commitment, and neither category is an operating aircraft. Structured operates_aircraft relationships consequently cover only types present in the current fleet table.
Fleet development
Delta has combined acquisitions, leases and used-aircraft transactions with new production orders. This produces an unusually varied fleet by age and origin. The A220, A321neo, A330neo and A350 populations provide newer aircraft, while long-serving 717s, A320s, 757s and 767s remain active during a staged renewal.[1]
Fleet renewal is not a one-for-one process. New deliveries can support growth, replace older types, change gauge or introduce a new mission. The A350-1000 and 787-10 commitments are future long-haul capabilities; the filing does not assign each ordered aircraft to a particular retirement.
Registration and status notes
Delta mainline and Delta Connection aircraft carry United States N registrations. The SEC filing supplies subtype, ownership-category totals and operator-level regional counts, but not a complete registration-to-MSN table. No serial number, delivery date or current serviceability has therefore been inferred.
An individual-aircraft record should distinguish registered owner, operator, marketing brand, lessor and dated status. The regional structure makes this especially important: an aircraft may be owned by Delta, operated by Endeavor and marketed as Delta Connection without those three roles being equivalent.[1]
