Each check covers the base adult allowance on the linked page. Your route, cabin, benefits or operating carrier may change the allowance.
Add your packed bag dimensions to compare them with this airline rule.
Some airlines include only a smaller underseat item with basic fares. Larger cabin bags can require a paid bundle, priority service, or eligible ticket.
British Airways publishes 56 x 45 x 25 cm for the cabin bag, and at the gate the sizer frame decides — not your tape measure. Enforcement varies by airport and crew, but a bag within 1 cm of any limit is always a gamble. Hard shells can't squeeze and soft bags bulge once packed — leave yourself a margin.
