Aer Lingus Baggage Allowance 2026

The cabin bag limit is 55 x 40 x 24 cm (21.5 x 15.5 x 9.5 in) and 10 kg (22 lb), and the airport gauge measures it with wheels and handles on. Across the Atlantic, every fare brings this bag and a personal item free, Saver included. On flights within Europe and to the UK, only Plus and Advantage include it in the price.

Since March 3, 2026 the 10 kg rule also covers Aer Lingus Regional flights within Ireland and the UK, between the two, and to Europe.

Two Aer Lingus pages give different sizes: 40 x 30 x 20 cm (15.5 x 11.5 x 8 in) on its baggage information page and 25 x 33 x 20 cm (10 x 13 x 8 in) on a carry-on page. Every passenger may bring one small item, such as a handbag or laptop bag, at no charge. It has to fit under the seat in front of you.

Plus and Advantage include the 10 kg (22 lb) cabin bag on flights within Europe and between Ireland and the UK, and Saver does not. Saver passengers can buy the bag, priced from €9.99 on one Aer Lingus page we could not confirm on the live site, or hand it in at check-in for free. Turn up at the gate with it unpaid and the charge is €35.

A Saver passenger who drops the 10 kg bag at the check-in desk pays nothing, so the €35 charge only hits bags that reach the boarding gate.

Smart and Flex economy fares include one checked bag of 23 kg (50 lb), and Business Class includes three bags with a combined 69 kg (150 lb). Economy Saver comes with no free checked bag. All transatlantic fares keep the free carry-on and personal item.

On one booking between North America and the UK or continental Europe, the transatlantic allowance applies to every Aer Lingus flight on the ticket, short-haul leg included.

Saver pays USD 54.99 online for a 20 kg bag, USD 59.99 for 25 kg and USD 64.99 for 30 kg, per bag each way. On other fares, extra bags cost USD 74.99, 79.99 and 84.99 online. At the airport, any fare pays USD 100 for a 23 kg bag, so the online Saver price is lower.

One 20 kg bag is included on Plus, Advantage and AerSpace, while Saver pays for every checked bag. Aer Lingus prices Saver bags by distance: its baggage information page shows €28 (Near), €45 (Mid) and €60 (Far) for 20 kg, but another Aer Lingus page shows €25, so we mark the fee as disputed. You can book up to three checked bags each way.

No single checked bag may weigh more than 32 kg (70 lb) or measure more than 158 cm (62 in) once you add length, width and height. Within that cap, transatlantic economy bags are included at 23 kg (50 lb) and European bags at 20 kg. Business Class passengers share 69 kg across their three bags.

Across the Atlantic, a bag weighing 23 to 32 kg (50 to 70 lb) costs USD 100 extra. In Europe, excess weight costs €10 per kilo. Aer Lingus publishes no separate oversize fee on the pages we could open, and 158 cm is the size ceiling for any bag.

Four groups get bags without upgrading: - AerClub Silver, Platinum and Concierge members keep the 10 kg cabin bag, Aer Lingus Regional flights included. - Avios Reward Flight bookings include a 20 kg checked bag and a 10 kg cabin bag. - Adults travelling with an infant get the 10 kg cabin bag (unverified). - Passengers connecting to or from a transatlantic or interline flight get the 10 kg cabin bag (unverified). No military or credit card checked bag waiver appears on the Aer Lingus pages we fetched.

No, pets can't fly in the cabin, and animals must be at least 15 weeks old to travel in the hold. You book hold travel through a pet agent at IAG Cargo, which sets the fee and container limits. Animals brought to passenger check-in are refused, and some dangerous and snub-nosed breeds are not accepted. Trained service dogs can fly with passengers who have a disability or reduced mobility.

Aer Lingus carries no animals at all on its A321neo LR aircraft because their cargo holds are not ventilated.

A €35 fee applies when a 10 kg bag reaches the boarding gate in Europe without being part of your booking. Bags go into airport gauges with wheels and handles counted. Handing the same bag in at check-in costs nothing, which gives Saver passengers a free way out.
