British Airways (BA) Baggage Allowance Calculator

British Airways permits one carry-on bag weighing up to 23 kg with maximum dimensions of 56×45×25 cm (length × width × height). Weigh your bag at home and budget a 0.5 kg margin for souvenirs: British Airways charges for every kilogram of checked weight beyond 23 kg.

Personal items travel free in addition to the carry-on on British Airways (BA) — a handbag or small laptop bag under the seat is never counted against your allowance.

The checked allowance on British Airways is 23 kg per standard bag — bag-inclusive fares are one of this carrier's quiet value levers. Additional bags cost $100 USD each on British Airways; bag dimensions should total no more than 158 cm (62 in) linear — most standard suitcases comply.

British Airways includes the first checked bag — a differentiator on longer trips. Overweight pricing runs $10/kg past 23 kg either way.

Two fee lines dominate a British Airways excess bill: $100 for each additional checked bag and $10 per kilogram above 23 kg. Compare strategies before paying: a second 18 kg bag at $100 often beats $10/kg overweight on one heavy case — the calculator tests both configurations for British Airways (BA).

The cheapest fixes are free on British Airways too: distribute weight across bags, wear the heavy coat, pocket the chargers. Pre-booking British Airways extra bags online locks the lowest rate.

Skis, golf clubs and bikes count as ordinary checked bags on British Airways up to 23 kg; oversize items above 158 cm linear may incur a flat $75–150 surcharge. Musical instruments on British Airways: small instruments (violin, flute) can travel as carry-on if they fit the sizer; larger ones (cello, guitar) usually require a separate seat or checked handling in a hard case.

Pack fragile and valuable items carefully — British Airways's liability for damage to improperly packed special items is limited, and hard-shell cases settle most disputes before they start.
