British Airways Baggage Rules: Carry-On and Fees

BA's cabin bag, the one that goes in the overhead bin, is capped at 56 by 45 by 25cm, or 22 by 18 by 10 inches, including wheels and handles. That's confirmed identically across every fare tier BA sells, from Economy Basic up to First.

There's no published numeric weight limit. Instead, BA applies a fit test: you have to be able to lift your own cabin bag into the overhead bin unassisted. Passengers with accessibility needs that prevent lifting their own bag are allowed a cabin bag that an able-bodied adult could reasonably lift instead. That lift-it-yourself standard means BA's real-world enforcement can vary more by gate agent than a strict number would, so if your bag is packed heavy, it's worth testing whether you can actually lift it overhead before you get to the airport.

The smaller item, BA's 'hand bag', is capped at 40 by 30 by 15cm, or 16 by 12 by 6 inches, and has to fit under the seat in front of you. Like the cabin bag, no numeric weight limit is published for it.

This hand bag is included free on every fare, including Economy Basic, and BA specifically notes it can hold essentials like medication, electronics, and passports, framing it as the bag you'd want quick access to during the flight.

Yes, and this is the detail that surprises a lot of travelers. BA's cheapest fare, Economy Basic, includes both the free hand bag and the free cabin bag, identical to every pricier fare tier. The only thing Economy Basic strips out is checked baggage.

That's the opposite of how United or Frontier structure their cheapest fares, where the bottom tier often drops down to a personal-item-only cabin allowance. On BA, your carry-on situation doesn't change no matter which fare you book. Only your checked bag allowance does.

Economy Basic includes zero free checked bags. Standard Economy includes one bag up to 23kg (51 lbs). Premium Economy includes one or two bags depending on route, also at 23kg. Business includes two bags at 32kg (70 lbs) each, and First includes three bags at 32kg each.

British Airways Club Gold or Silver members, along with oneworld Emerald and Sapphire status holders, get one additional bag added to whichever cabin they're flying, sometimes with a weight bump too. If you're on Economy Basic and need to check a bag, BA prices it dynamically at booking rather than publishing one flat rate, so check the fee in Manage My Booking before you fly.

Premium Economy is the one cabin where the included bag count genuinely depends on your specific route rather than a flat rule, ranging from one bag to two depending on where you're flying. BA points passengers to Manage My Booking or its baggage calculator to confirm the exact number for a given itinerary rather than publishing one universal Premium Economy figure.

If your checked bag falls between 23kg and 32kg (51 to 70 lbs), BA charges a flat overweight fee of £65, which converts to roughly $100 USD depending on where you're flying from. Cash and Avios points aren't accepted for this fee at several major airports, including Heathrow, Gatwick, and airports across North America.

BA doesn't accept checked bags heavier than 32kg (70 lbs) at all. On size, bags up to 90 by 75 by 43cm are standard; larger 'out of gauge' bags up to 190 by 75 by 65cm are usually still accepted with some restrictions, like needing to be checked in at a dedicated bag drop at least 90 minutes before departure.

One more detail worth knowing before you pack: BA refuses fragile large electronic screens, including TVs, monitors, and gaming displays, as hold baggage entirely, regardless of size or weight. If you're moving a large screen, it needs a different shipping method, not a checked bag, since no amount of protective packaging changes BA's outright refusal on this specific item category.

British Airways is unusually generous on carry-on weight: it publishes no numeric limit at all for either the cabin bag or the hand bag, only a lift-it-yourself fit test. That's a real outlier compared to other long-haul international carriers, where a published cabin weight limit is closer to the norm.

Qatar Airways caps Economy cabin baggage at 7kg, Singapore Airlines also caps it at 7kg, and Iberia allows up to 10kg. Against that field, BA's no-weight-limit approach means a heavier laptop bag or camera bag that would get flagged on a Gulf or Asian carrier can usually travel free on BA, as long as you can still lift it into the bin yourself.

If you fly more than just British Airways, it helps to browse every airline's carry-on rules in one place, since BA's naming conventions (cabin bag versus hand bag) don't map directly onto how other airlines describe the same two pieces.

Our luggage size directory breaks down real bag dimensions pulled from actual product listings, which makes it easier to confirm your specific suitcase clears BA's 56 by 45 by 25cm cabin bag limit before you get to the airport.
