British Airways Hand Baggage: Basic, Business & First
BA Basic includes a 56×45×25 cm cabin bag and a small underseat item. Compare cabin classes, lifting requirements and partner-flight exceptions.
BA Basic includes a cabin bag. The official cabin allowance is one 56×45×25 cm bag, including wheels and handles, plus a smaller underseat item. Business and First keep that cabin piece count; their extra checked baggage is separate.
Check your BA cabin bag with your packed measurements. For the broader policy and tool inputs, see British Airways carry-on rules.
Compare cabin classes
| Cabin or fare | Cabin items | What differs |
|---|---|---|
| Basic / no checked baggage | One cabin bag + one small item | No included checked bag |
| Economy / Premium Economy | Same cabin item count | Checked allowance depends on booking |
| Business / First | Same cabin item count | Extra hold baggage is not an extra overhead bag |
Underseat size and weight
The cabin-specific sections list 40×30×15 cm for the small item. A calculator result on that same page still shows 45×36×20 cm. Our BA record uses the smaller published limit; confirm your booking before relying on the larger box.
No numeric cabin weight cap is stated there. Unassisted lifting is required, with accessibility provisions. Keep essentials in the smaller item: the larger cabin bag may go in the hold.
Before departure
Measure the packed bag, rather than relying on its product name. Select the actual operating carrier for partner flights, and check every segment on a connecting itinerary. Read the allowance in your reservation before purchasing extra baggage. This guide does not claim that Heathrow or Gatwick checks bags more often.
