The personal item on Economy fares can measure up to 40 × 30 × 15 cm (15.5 × 12 × 6 in) and weigh up to 23 kg (51 lb). It is included in the fare. The cabin bag on Economy fares can measure up to 56 × 45 × 25 cm (22 × 17.5 × 10 in) and weigh up to 23 kg (51 lb). It is included in the fare. Dimensions include wheels and handles — measure the bag packed, not empty, because a full front pocket can add a couple of centimetres.

Airlines change cabin-bag rules often. These figures were checked in September 2026. Always confirm on British Airways’s official baggage page (opens in a new tab) before you fly — the airline’s own rules apply at the gate.

How to pack for British Airways’s limits

British Airways distinguishes between a small personal item (40 × 30 × 15 cm) and a larger cabin bag (56 × 45 × 25 cm). Keep the things you need during the flight — passport, wallet, phone, chargers, medication — in the personal item, so they stay with you even if the cabin bag has to go in the hold when overhead space runs out.

  • Wear your heaviest shoes and jacket on the plane — they don’t count towards the bag.
  • Roll or fold clothes into packing cubes and keep the bag’s depth in check; depth is the measurement most bags fail.
  • Plan outfits that share pieces, so three tops and two bottoms cover a week. The outfit planner works this out per day.
  • Weigh the packed bag at home: 23 kg (51 lb) is the limit to beat. Luggage scales are cheap and save surprises at the gate.

Liquids in hand luggage

Most airports still limit cabin liquids to containers of 100 ml (3.4 oz) in one clear 1-litre bag. Some airports with new scanners allow more — check your departure airport before you fly.

How British Airways compares

If your bag is at British Airways’s cabin bag limit (56 × 45 × 25 cm), it also fits the matching rule at 1 other airline we track:

  • easyJet — Large cabin bag add-on: 56 × 45 × 25 cm

Want one bag for every airline? Taking the smallest length, width and depth across all cabin-bag rules we track gives 55 × 35 × 20 cm (21.5 × 14 × 8 in): a bag within that size fits all of them. Sides are compared longest to longest, because a bag can be turned to fit the sizer.

Longest side 56 cm is 22 in. Inches are rounded to the nearest half inch.
