Baggage fees
No reliable fixed price is listed here. Check your booking for the cost of adding a bag; an unlisted price does not mean it is free.
Official baggage policyHow to use this policy
Check cabin bag dimensions, weight and personal-item limits separately. A bag has to pass every published limit at once; being under the length and width limit does not help if the depth, weight, or fare-specific allowance is tighter.
Editorial signal only. Measure the packed bag and verify the operating carrier's rule.
Aer Lingus liquids policy
Security rules depend on departure and transfer airports. Aer Lingus links EU liquid-screening guidance and identifies TSA rules for US departures. Confirm current airport container limits and medical/infant exceptions; the cabin-bag allowance itself does not establish security clearance.
Family & Infants
Infant (under 2)
European mainline lap-infant fare is EUR/GBP 25 each way before applicable taxes/charges; North America is 10% of the adult fare. Regional has separate conditions. An adult with an infant qualifies for the listed European cabin inclusion; no separate infant 10 kg cabin allowance is inferred.
Stroller
One fully collapsible buggy/stroller is free for an infant or child booking, plus one car seat, booster seat or travel cot. No universal cabin stowage or aircraft-door return guarantee established.
Car seat
Cabin use requires a purchased seat and an approved forward-facing restraint with a 5-point harness, secured by the aircraft belt. Mainline and Regional age, width and seating conditions differ; arrange with the airline. Free equipment carriage does not guarantee cabin use.
Children's allowance
Children 2–11 travel in their own seat; cabin entitlement follows the booked route/fare. Infant transatlantic 10 kg checked allowance is a hold-baggage benefit, not another cabin bag.
