British Airways

Allowed dimensions: 56x45x25 cm · Maximum weight: 23 kg

The context in a few words

In the broader airline landscape, British Airways plays the reference-carrier role: a wide fleet, alliance memberships, and a carry-on policy built around passengers who travel between continents.

56x45x25 cm, 23 kg is above the market average. Worth noting if you travel with a 40-50 L backpack or an extended cabin case.

One useful benchmark: on British Airways, cabin baggage typically fits the overhead bin of an Airbus A320 or Boeing 737, the most common types on their network. The 56x45x25 cm format at 23 kg matches standard bin dimensions, no more. Even seemingly compatible extended cases are best avoided.

Gate staff are typically less zealous than on low-costs, but the published grid still applies. Travelling planning ahead saves a place in the gate-check queue — "free" hold luggage that costs time on arrival.

Don't overlook the allowed personal item — it's often the trick that saves a light trip. Handbag, laptop sleeve or small backpack, as long as it slides under the seat in front. On British Airways, that's where books, headphones, water and flight essentials live without eating into the main carry-on.
