Aer Lingus baggage allowance
Your allowance on a full-service carrier is set by three things: the fare family you booked, the cabin you are travelling in, and the route.
Long-haul economy tickets normally include at least one checked bag plus a cabin bag; premium cabins include more, and frequent flyer or alliance status usually adds to it. Basic or "light" economy fares are the exception — they are increasingly sold cabin-baggage-only, on the same aircraft, and are easy to book by mistake when sorting by price.
Short-haul and domestic fares are the other common surprise: the same airline that includes two bags on an intercontinental route may include none on a one-hour hop. The allowance printed on your booking confirmation is the one that counts.
Aer Lingus cabins
Aer Lingus sells multiple cabins on its long-haul aircraft, typically economy, a premium economy, and a lie-flat business class, with a first class on selected routes and aircraft. Cabin layout varies by aircraft type even on the same route, so the seat map attached to your specific flight is the one to check before choosing a seat.
Aer Lingus fleet
Aer Lingus operates Airbus Industrie A320, Airbus Industrie A319, Airbus Industrie A321, Airbus Industrie A330, Airbus Industrie A330-200 on the routes in our data. Aircraft type varies by route and by day, and airlines swap equipment at short notice, so treat this as the typical fleet on this network rather than a guarantee for your flight.
