Aer Lingus cabin baggage explained

Aer Lingus separates a small under-seat handbag that comes with every fare from the 10 kg wheeled cabin bag that only some short-haul fares include. On short-haul the Saver fare is the one to watch, because it does not come with the larger bag.

What your fare changes

Every short-haul fare includes the 33 × 25 × 20 cm under-seat item. The 55 × 40 × 24 cm cabin bag up to 10 kg is included on short-haul fares other than Saver; Saver customers add it as a paid option. Long-haul and Business allowances differ, so use the specific booking.

What to check before you fly

The free handbag is genuinely small at 33 × 25 × 20 cm, so a normal backpack usually only travels once you have paid for or included the 10 kg bag. Measure with wheels and handles, and remember a full cabin can still send a compliant bag to the hold.

Worked bag-size example

Take a wheeled cabin bag measuring 54 × 39 × 22 cm and weighing 9 kg. Compare it with the cabin-bag limit of 55 × 40 × 24 cm and 10 kg.

Side-by-side calculation
55 − 54 = 1 cm · 40 − 39 = 1 cm · 24 − 22 = 2 cm

The smallest dimensional margin is 1 cm, so the bag is within the size limit. Its weight margin is 1 kg.

We compare the three outside edges after orientation, including protruding parts. A result with less than 0.5 cm of clearance is marked tight because measuring and packing can change the real size.
