British Airways vs Air France — carry-on baggage compared | CabinPax

Carry-on rules side by side: maximum dimensions, weight allowance, personal item. Data updated April 2026.

• British Airways: 56x45x25 cm · 23 kg
• Air France: 55x35x25 cm · 12 kg

Both carriers operate in the same league, so the gap on carry-on rules is more granular than philosophical. A few centimetres here, a kilo there — but real consequences at the gate.

On size, British Airways wins by a clear margin (56x45x25 cm versus 55x35x25 cm). For a traveller hesitating between the two on a comparable price, that's the deciding argument when the bag is borderline.
