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. Airport behavior varies; the published allowance still governs.
British Airways liquids policy
Check the departure airport’s current security rules for liquids, alongside British Airways restricted-item guidance.
Family & Infants
Infant (under 2)
An infant without a seat has a 23 kg checked-bag allowance except on hand-baggage-only Basic fares. Extra checked baggage cannot be purchased for a lap infant.
Stroller
A fully collapsible pushchair may be one of two free baby-equipment items checked into the hold per child.
Car seat
A car or booster seat may be one of the two free baby-equipment items checked into the hold.
Children's allowance
Children and infants with their own seat have the same free baggage allowance as adults.
