It's never a seat count, and configurations change with retrofits. An airline needs at least 25 nonstop routes on the Airbus A321, on its own metal, and at least 3 aircraft types that clear the same bar to be listed, so a smaller Airbus A321 operation can be missing. ### More airlines with an Airbus A321 page - [Air Arabia (G9)](https://2lnr.com/seatmaps/g9/a321.md) - [Air Astana (KC)](https://2lnr.com/seatmaps/kc/a321.md) - [Air France (AF)](https://2lnr.com/seatmaps/af/a321.md) - [Air India (AI)](https://2lnr.com/seatmaps/ai/a321.md) - [Air Macau (NX)](https://2lnr.com/seatmaps/nx/a321.md) - [Air Transat (TS)](https://2lnr.com/seatmaps/ts/a321.md) - [Alaska Airlines (AS)](https://2lnr.com/seatmaps/as/a321.md) - [All Nippon Airways (NH)](https://2lnr.com/seatmaps/nh/a321.md) - [Asiana Airlines (OZ)](https://2lnr.com/seatmaps/oz/a321.md) - [Austrian Airlines (OS)](https://2lnr.com/seatmaps/os/a321.md) - [Beijing Capital Airlines (JD)](https://2lnr.com/seatmaps/jd/a321.md) - [British Airways (BA)](https://2lnr.com/seatmaps/ba/a321.md) - [Cebu Pacific (5J)](https://2lnr.com/seatmaps/5j/a321.md) - [Egyptair (MS)](https://2lnr.com/seatmaps/ms/a321.md) - [Etihad Airways (EY)](https://2lnr.com/seatmaps/ey/a321.md) - [EVA Air (BR)](https://2lnr.com/seatmaps/br/a321.md) - [Hong Kong Express Airways (UO)](https://2lnr.com/seatmaps/uo/a321.md) - [Iberia Airlines (IB)](https://2lnr.com/seatmaps/ib/a321.md) - [Jet2.com (LS)](https://2lnr.com/seatmaps/ls/a321.md) - [Jetstar (JQ)](https://2lnr.com/seatmaps/jq/a321.md) - [Philippine Airlines (PR)](https://2lnr.com/seatmaps/pr/a321.md) - [Shenzhen Airlines (ZH)](https://2lnr.com/seatmaps/zh/a321.md) - [SriLankan Airlines (UL)](https://2lnr.com/seatmaps/ul/a321.md) - [Swiss International Air Lines (LX)](https://2lnr.com/seatmaps/lx/a321.md) - [TAP Air Portugal (TP)](https://2lnr.com/seatmaps/tp/a321.md) - [Wizz Air (W6)](https://2lnr.com/seatmaps/w6/a321.md) ## Checked cabins on the Airbus A321 [Delta Air Lines](https://2lnr.com/seatmaps/dl/a321.md): Delta First, Delta Comfort, Delta Main (last checked September 8, 2026). Its page has the seat layout and seat type for each cabin. Only airlines whose own page shows checked cabin layouts appear in this section. An airline can swap the aircraft on the day. ## Frequently asked questions about the Airbus A321 **Does the Airbus A321 have the same cabins on every airline?** No. Each airline fits its own cabins and seats, so the Airbus A321 on easyJet UK and the Airbus A321 on American Airlines can be quite different inside, and one airline can fly more than one layout. On the Delta Air Lines Airbus A321, the cabins 2LNR has checked are Delta First, Delta Comfort, and Delta Main, as last checked September 8, 2026. **Can I see the Airbus A321 seat map for my flight?** Yes, on Pro, for the specific flight and date you're on. 2LNR reads that flight's Airbus A321 seat map when you ask, scores the open seats inside your cabin and marks paid seats as paid. ## No cabin diagram here 2LNR doesn't publish stored seat diagrams for the Airbus A321 or any other aircraft. On Pro it reads the live seat map for a specific flight and date, which is the version that survives an aircraft swap. For a drawing of a cabin you haven't booked, a maintained library such as [AeroLOPA](https://www.aerolopa.com/) is the right tool. ## Other Airbus A320 family aircraft - [Airbus A318](https://2lnr.com/seatmaps/aircraft/a318.md) - [Airbus A319](https://2lnr.com/seatmaps/aircraft/a319.md) - [Airbus A319neo](https://2lnr.com/seatmaps/aircraft/a319neo.md) - [Airbus A320](https://2lnr.com/seatmaps/aircraft/a320.md) - [Airbus A320neo](https://2lnr.com/seatmaps/aircraft/a320neo.md) - [Airbus A321neo family](https://2lnr.com/seatmaps/aircraft/a321neo.md) ## Related - [Seat maps by aircraft type](https://2lnr.com/seatmaps/aircraft.md) - [Seat maps by airline](https://2lnr.com/seatmaps.md) - [How to read an airline seat map](https://2lnr.com/guides/airline-seat-maps.md) - [What replaced SeatGuru](https://2lnr.com/compare/seatguru.md) ## See the seats on your Airbus A321 flight Free to start.
