British Airways cabin bag dimensions and bag size

The maximum British Airways carry-on size is 56 x 45 x 25 cm, or 22 x 18 x 10 inches as British Airways publishes it. These measurements include wheels, handles, and any external pockets, so a bag marketed as "22 inch" can go over if its wheels push the total past 56 cm. Always measure your bag packed, not empty.

British Airways carry-on weight limit

British Airways does not publish a specific carry-on weight limit. Our guidance: pack it light enough that you can lift the bag into the overhead bin yourself.

Does British Airways charge for carry-on bags?

No. British Airways includes a free carry-on bag plus a free personal item on every fare, including the Basic fare.

British Airways overhead bin size by aircraft

Cabin bag may be moved to the hold if overhead space is limited on a full flight; personal item is guaranteed to stay in the cabin.

Common British Airways carry-on mistakes

  • Assuming BA has no weight limit; you must be able to lift the bag into the overhead bin unaided.
  • Bringing a cabin bag larger than 56x45x25 cm, which is generous vs peers but still enforced at sizers.
  • On a Basic (Hand Baggage Only) fare, booking a bag at the airport rather than pre-paying online.

What happens if your bag does not fit on British Airways

If overhead space runs out, BA moves oversize or surplus cabin bags to the hold; the personal item stays with the passenger.

British Airways vs Virgin Atlantic carry-on

British Airways allows a notably larger cabin bag than most European peers at 56x45x25 cm plus a 40x30x15 cm personal item, and publishes no firm weight cap, only the lift-unaided rule. Virgin Atlantic's Economy Light also includes a cabin bag, but BA's Economy Basic fares are strictly hand-baggage-only on any haul, while standard (non-Basic) World Traveller fares still include a checked bag. BA enforces sizers more consistently than its no-weight reputation suggests, and overflow bags on full flights are gate-checked rather than charged.

Longhaul standard World Traveller fares include 1 checked bag up to 23 kg / 50 lb at 90 x 75 x 43 cm (35 x 30 x 17 in, 82 in linear). Economy Basic fares (hand baggage only) include no checked bag on any haul. Second and additional bag fees are no longer published as flat amounts: as of September 2026 BA quotes them only through its baggage calculator (route- and cabin-dependent), so no flat second-bag fee is listed here. Over-23kg fee is $100. Max single bag 32 kg / 70 lb. The international first-bag fee is left unpublished because Economy Basic, the cheapest fare, includes no checked bag and BA prices bags only through its baggage calculator.

Ways to skip the British Airways checked bag fee

  1. Pack carry-on only. Confirm your bag fits the British Airways carry-on size.
  2. Check your British Airways Club status. See whether your tier includes a free checked bag on British Airways.

BA does not allow pets in the cabin except registered assistance dogs. Pets must be booked as cargo, priced by container size, pet weight and distance. A bicycle in a cover or box (up to 190 x 95 x 65 cm) counts as one item of your checked allowance; on Economy Basic or once your allowance is used it is charged as an extra checked bag, with no flat bike fee published.

Does my checked bag transfer to British Airways' partner airlines?

Yes, on a single ticket. British Airways holds checked-bag interline agreements with 164 airlines, so when your itinerary is booked as one ticket your bag is through-checked to the final destination on any of those carriers. You collect it once, at the end, not at the connecting airport. If your onward flight is on a carrier not on this list, or the two legs are on separate tickets, you must claim the bag at the connection, clear customs where required, and re-check it yourself, so allow extra connection time.

Through-check partners we cover (47 of 164):

Plus 117 more partner airlines not yet profiled on this site.

British Airways also files e-ticket interline with 157 carriers, which lets two airlines sell a single through-ticket. Through-checked bags depend on the baggage agreement above, not the e-ticket count. Interline partners verified May 2026 from ExpertFlyer, Travel Information, Interline Agreements (Premium tier).
