Aer Lingus cabin bag dimensions and bag size

The maximum Aer Lingus cabin bag size is 21.7 x 15.7 x 9.4 inches, which works out to 55 x 40 x 24 cm. These measurements include wheels, handles, and any external pockets. Gate sizers on Aer Lingus match the published limits closely, so a bag marketed as "22 inch" can fail if its wheels push the total past 21.7 inches. Always measure your bag packed, not empty.

Aer Lingus cabin bag weight limit

Aer Lingus limits carry-on bags to 10 kg (22 lb). Most domestic check-in counters do not weigh carry-ons, but gate agents can pull bags that look heavy. If your bag is over the limit, expect to be asked to check it, sometimes at a higher gate-check fee.

Does Aer Lingus charge for cabin bag bags?

No. Aer Lingus includes a free carry-on bag plus a free personal item on most fares. The exception is Basic Economy, where some routes restrict you to a personal item only. Check your specific fare rules before you book.

Aer Lingus vs British Airways carry-on

Aer Lingus and British Airways both dominate Ireland-UK and transatlantic flows from Dublin and London, but their cabin rules diverge sharply at the bottom. BA's hand baggage allowance is 23 kg split across a 56x45x25 cm cabin bag and a 40x30x15 cm laptop-size personal item, included in every fare including Basic. Aer Lingus' Saver fare is closer to a Ryanair model: you get only a 25x33x20 cm personal item and must pay 9.99 EUR or check a bag to bring 10 kg onboard. Aer Lingus mainline cabin bags are also slimmer at 55x40x24 cm versus BA's 56x45x25 cm. For a like-for-like Plus or Advantage fare on Aer Lingus you get 10 kg at 55x40x24 cm plus a personal item, still lighter than BA's 23 kg combined limit.
