Aer Lingus

Allowed dimensions: 55x40x24 cm · Maximum weight: 10 kg

The context in a few words

Aer Lingus belongs to the heritage carriers of Irlande, the airlines that grew alongside commercial aviation and now run dense international networks. Carry-on policy reflects that pedigree: roomy allowances, broadly aligned with IATA standards.

Allowed format: 55x40x24 cm, 10 kg. That's generous compared with what most European low-costs publish — a real argument for travellers weighing options.

In concrete terms: a typical "cabin format" suitcase weighs 2–3 kg empty for 55×40×20 cm. On Aer Lingus, once filled, the usable margin against the 10 kg ceiling shrinks to a few kilos. Frequent travellers tune the bag to exact spec to avoid gate-side reclassification fees.

Tip from the road: on these airlines, the cabin allowance is often paired with a personal item (handbag, laptop bag). Using both tiers properly maximizes capacity without overshooting.

The personal item — handbag, sleeve, underseat bag — makes all the difference on long flights. On Aer Lingus, used well, it frees the cabin case for essentials and keeps liquids, electronics and papers within reach during the flight.

Business class gets extended weight and dimensions — 10 kg on the most generous tier. Not to be confused with a courtesy upgrade: it's a contractual allowance.
