Routes and cabin configurations, not a cabin diagram." canonical: "https://2lnr.com/seatmaps/dl/a321" url: "https://2lnr.com/seatmaps/dl/a321.md" date_modified: "2026-09-20T02:14:56Z" --- # Delta Air Lines Airbus A321 seat maps and routes Delta Air Lines (DL) operates the Airbus A321 across 322 nonstop routes and 82 airports in 2LNR's schedule data, which makes it a backbone of the network rather than a specialist assignment. The busiest of those routes are New York to Atlanta, Atlanta to New York, and Boston to Atlanta. 2LNR does not publish a stored cabin drawing for this aircraft; it reads the live seat map for the specific flight you are looking at, which is the only version that survives an aircraft swap.

[Get started free](https://2lnr.com/login) [The whole DL fleet](https://2lnr.com/seatmaps/dl.md) 322 Nonstop routes 82 Airports served Per flight How the live map reads ## There is no cabin diagram on this page 2LNR does not publish stored seat diagrams or per-seat comfort ratings, for this aircraft or any other, and it will not invent them. What it has is the live seat map for a specific DL flight and date, read at the moment you ask, on Pro. That is a different thing from a drawing of the type, and it is the only version that survives an aircraft swap. If a diagram is what you came for, a maintained library such as [AeroLOPA](https://www.aerolopa.com/) is the right tool. ## What is on this page Every nonstop route Delta Air Lines currently schedules the Airbus A321 on, taken from the flight schedules 2LNR collects continuously. The aircraft is a Airbus A321, a narrowbody. DL files it as 321 in its schedules; those spellings are treated as one aircraft here rather than as separate types. ## Configurations recorded for DL The configuration Delta Air Lines records for this aircraft. - Airbus A321 These are the aircraft names in 2LNR's own reference for DL, not seat counts and not a cabin layout. The reference is seeded rather than refreshed on a schedule, so no currency date is claimed for it. Configurations change with retrofits, and an airline can assign a different aircraft on the day, so treat this as context rather than as what you will board. ## Where DL flies the Airbus A321 322 nonstop routes across 82 airports, grouped by departure city. A route appears here when DL has scheduled this aircraft on it; most routes see more than one type across a season. ### Albany (ALB) - [Albany (ALB) to Atlanta (ATL)](https://2lnr.com/routes/alb-atl.md) ### Atlanta (ATL) -

The full list is on this page, grouped by departure city, and each route opens that city pair's own page. Schedules move seasonally, so this reflects what DL currently has filed rather than a permanent assignment. **Can I see the Airbus A321 seat map for a DL flight?** Yes, on Pro, and it is the live map for the specific flight and date rather than a drawing of the type. 2LNR scores the open seats inside your cabin, marks paid seats as paid, and can keep watching for a better one. That is deliberately different from a static Airbus A321 diagram, which cannot tell you whether 12A is free or whether the aircraft was swapped. **Is the Airbus A321 the only aircraft on these DL routes?** No. A route appears here when DL has scheduled the Airbus A321 on it, and most routes see more than one aircraft type across a season or even a day. That is exactly why 2LNR reads the map per flight: the honest answer to which cabin you will get is a per-departure answer, not a per-route one. **Does 2LNR have seat ratings for the Airbus A321?** Not as a published library of per-seat comfort ratings for the Airbus A321, and this page will not invent them. What 2LNR scores is the seats actually open in your cabin on your DL flight, so the answer is a seat you can select rather than a general opinion about a row. For browsing a Airbus A321 cabin layout on an aircraft you have not booked, a maintained diagram library such as AeroLOPA remains the better tool. ## See the seats on your DL flight Free to start.
