Cabin bag sizes by airline, in cm and inches

Every row comes from the airline's own website, read on 1 October 2026. Centimetres are shown in the airline's order; inches are the airline's own figures when it publishes them, otherwise converted and rounded down. "Not published" means the airline does not give that figure: we never fill it with an estimate.
