British Airways lets every passenger take two bags into the cabin, free of charge. The cabin bag maximum size is 56 x 45 x 25cm — including wheels and handles — and goes in the overhead locker. The handbag or small backpack can be up to 40 x 30 x 15cm and goes under the seat in front. There is no weight limit on either bag. Both bags are included in every BA fare, including the cheapest Economy Basic tickets.

British Airways cabin bag size
The BA cabin bag limit is 56 x 45 x 25cm (22 x 18 x 10in). This includes wheels and handles, so the whole bag needs to fall within those dimensions when fully packed.
The bag goes in the overhead locker. BA requires you to lift it there yourself. Staff will not assist with loading, and if you cannot manage it unassisted, the bag will be moved to the hold, potentially at extra cost.
The 25cm depth allowance is notably generous compared with budget airlines. A bag measuring 55 x 40 x 20cm, the standard for Ryanair Priority or easyJet’s large cabin bag, fits easily within BA’s limit. If you already own a bag sized for budget airlines, it will work on BA without any issue.
BA does not operate sizers or gauges at most gates in the way Ryanair does. That said, if a bag is clearly oversized, staff will notice.
British Airways handbag and personal item size
In addition to your cabin bag, BA allows one handbag, small backpack, or laptop bag. The maximum size is 40 x 30 x 15cm (16 x 12 x 6in). This bag goes under the seat in front of you.
At 40 x 30 x 15cm, the allowance is practical. Most everyday handbags, laptop sleeves, and small backpacks fall within these dimensions. A 15.6-inch laptop bag is likely to be borderline on the 15cm depth measurement, so check the dimensions of your specific bag before you travel.
This bag should remain under the seat throughout the flight, not just at boarding. On a full flight, overhead space fills quickly. Using the underseat area for your handbag frees up locker space for the cabin bag, which is usually the bulkier of the two.
No weight limit: what this means in practice
British Airways does not set a weight limit for cabin bags or handbags. You can bring as heavy a bag as you can physically carry and lift into the overhead locker.
This matters because most budget carriers do impose limits. Ryanair limits priority cabin bags to 10kg and charges up to £75 at the gate if you exceed it. easyJet allows up to 15kg on its large cabin bag. On BA, neither limit applies.
In practice, this means you can pack a heavy cabin bag on BA without any surcharge. This makes BA a cost-effective choice for passengers who want to avoid hold baggage fees on routes where budget airlines charge for weight.
There is one constraint: you must be able to lift the bag into the overhead locker. If it is genuinely too heavy to lift, BA staff may redirect it to the hold.
Hand luggage allowance by cabin class
The hand luggage allowance is the same in every cabin: one cabin bag and one handbag, no weight limit. What changes between cabins is the checked baggage allowance.

Economy Basic is the cheapest BA fare. You get the full two-piece hand luggage allowance but no checked bag. If you need hold luggage, check whether upgrading to standard Economy, which includes one checked bag, costs less than adding a bag to an Economy Basic ticket. The difference is sometimes small.
Club Europe: business class on short-haul routes
On short-haul European flights, BA’s business cabin is called Club Europe. The hand luggage rules are identical to all other cabins: one cabin bag (56 x 45 x 25cm) and one handbag (40 x 30 x 15cm), no weight limit.
Club Europe passengers receive priority boarding. This matters because it means you board early, when overhead lockers are still mostly empty. On a full flight, earlier boarding reduces the chance of being asked to check your cabin bag at the gate due to lack of locker space.
Tips for getting the most from your BA hand luggage allowance
BA’s two-bag allowance and lack of weight limits give you more flexibility than most airlines. Here is how to use it well.
- Pack heavy items in your cabin bag. With no weight limit, there is no penalty for a heavy bag as long as you can lift it. Use this to avoid hold baggage charges when travelling with dense or heavy items.
- Use your handbag as an overflow bag. A 40 x 30 x 15cm bag holds a laptop, a change of clothes, and a washbag. Pack things you want during the flight here, and keep the cabin bag to items you do not need until landing.
- Measure your bag fully packed. The 56 x 45 x 25cm limit includes wheels and handles on a hard-shell case. Check the total dimensions with the bag packed and zipped, not empty. Soft bags compress; hard-shell cases do not.
- Economy Basic passengers: compare the cost of adding a bag. It may be cheaper to book the standard Economy fare, which includes a checked bag, than to add one to an Economy Basic ticket.
- Executive Club status improves your boarding position. Higher-tier members board earlier. Earlier boarding means better access to overhead lockers, which matters on full flights.
What happens if your cabin bag is too big at the gate?
If your bag does not fit in the overhead locker, BA staff will ask you to check it into the hold. Depending on the route and timing, this may incur a fee. The bag will also come off in the arrivals hall rather than being returned to you at the gate.
BA does not operate the same gate-fee system as Ryanair, where a fixed charge of up to £75 applies to bags that fail the sizer. However, a genuinely oversized bag will still be removed from the cabin.
On full flights, overhead space sometimes runs out even for passengers with correctly sized bags. Economy Basic boards last. If there is no locker space when you board, your bag may be taken to the hold without charge, but it will arrive in the baggage hall rather than with you at the gate.
How British Airways compares to other UK airlines
BA’s two-bag free allowance with no weight limit is one of the most generous of any UK carrier. Most low-cost airlines allow one free bag; a second requires payment or a fare upgrade.
Our full UK airline hand luggage comparison covers all eight major carriers side by side. In brief:
- Ryanair: free bag 40 x 20 x 25cm (underseat only). Overhead cabin bag requires Priority or a paid add-on. Gate fee up to £75.
- easyJet: free underseat bag included; large cabin bag for the overhead locker requires payment on many fares.
- Jet2: one cabin bag (56 x 45 x 25cm) free for all passengers. One of the more straightforward policies among UK carriers.
- British Airways: cabin bag plus handbag free in every cabin, including Economy Basic. No weight limit on either bag.
For passengers who carry a laptop and a full cabin bag, BA’s two-piece allowance represents a meaningful cost saving over budget alternatives, particularly on routes where Ryanair or easyJet charge £15 to £30 or more for an overhead bag.

Yes. BA allows one cabin bag (56 x 45 x 25cm, overhead) and one handbag, laptop bag, or small backpack (40 x 30 x 15cm, underseat) in every cabin. If your laptop bag fits within 40 x 30 x 15cm, it counts as your personal item and travels free alongside your cabin bag.
