13-airline comparison

Will a 40 × 30 × 15 cm bag fit?

It fits the published personal-item dimensions for all 13 covered airlines. The remaining question is entitlement: several carriers, including SWISS, vary the larger overhead bag by fare or route.

Fit is not entitlement. This table focuses on the small-item dimensions. Weight limits and the right to bring a larger overhead bag still depend on the airline and fare.

Why 40 × 30 × 15 remains useful

It is a conservative target across many large European carriers, but it is not a universal law and it should never override the operating airline's current published allowance.
