Aer Lingus

Aer Lingus is Ireland's flag carrier, owned since 2015 by International Airlines Group, the parent of British Airways and Iberia. It runs a focused operation out of Dublin, with secondary bases at Cork and Shannon, and its strongest card is short, efficient transatlantic flying that routes US travellers through Dublin to Europe, often clearing US immigration before they leave Ireland.

It is not a member of a global alliance. Aer Lingus left oneworld in 2007 and has stayed out, though it sits inside the transatlantic joint venture alongside British Airways, American and Iberia, so codeshare and frequent-flyer reach run through those partners and its own AerClub programme. Flying Aer Lingus feels mid-market rather than full-service: a tidy short-haul product across Europe, and a credible long-haul business cabin on the routes that earn it. The pitch is value and convenience over frills.

The configurations published here split cleanly into short-haul and long-haul. On the European and domestic side sit the ATR 72-600 turboprop and the Airbus A320 family, including the A320neo, A321neo LR and A321XLR. The turboprop and the standard A320s are all-economy single-aisle aircraft. The longer-range A321neo LR and A321XLR add a lie-flat business cabin up front for transatlantic work, which is what lets a narrowbody cross the ocean.

The widebodies are the A330-200 and A330-300, which carry the busy US routes. Both run a two-class layout: a forward business cabin in a staggered arrangement, then a large economy cabin behind it. Across the long-haul fleet the character is consistent, a compact premium cabin and a deep economy section, so the choice between an A330 and an A321XLR comes down more to route and timing than a wholly different product.

Long-haul business on the A330s and the A321XLR and neo LR is the standout: a fully flat bed, a reasonable amount of storage and a meal service that holds up against the bigger IAG carriers without claiming to be first class. The A330 cabin is the more spacious of the two; the A321XLR delivers the same flat bed in a narrower tube, so it feels a touch tighter but does the job on a daytime crossing. One thing to know up front: the staggered layout means seats are not equal, and not every business seat has direct aisle access, so the seat you pick matters more here than on a cabin with all-aisle-access rows. Seatback screens and improving wi-fi cover the long-haul fleet.

Economy is straightforward. Standard recliner seats, a buy-on-board model on short-haul, and a complimentary meal on transatlantic flights. Worth knowing: short-haul AerSpace is marketed as a premium seat but is really a blocked-middle economy product with priority perks, not a separate cabin, so it buys space and an easier boarding rather than a flat bed. On Europe, expect a clean, no-surprises ride rather than anything plush.

In long-haul business, the staggered layout is the thing to read before you book. The single seats that sit away from the aisle are the ones solo travellers want, with the most privacy and direct aisle access; the paired seats either have you stepping over a neighbour or being stepped over, so couples are better suited there than solo flyers. Check the published cabin layout for the specific aircraft, and avoid the first and last rows if you are sensitive to galley noise and footfall.

In economy, the exit rows and the bulkhead buy you extra legroom, with the usual trade-off of fixed armrests and no under-seat bag at the bulkhead. Steer clear of the back few rows near the rear galleys and lavatories on the A330s, where traffic and noise are heaviest, and avoid seats immediately ahead of an exit row, which sometimes have limited recline. On the A320 family and the ATR, the front rows load and unload fastest if a tight connection in Dublin is the priority.
