Fare type notes
Some airlines include only a smaller underseat item with basic fares. Larger cabin bags can require a paid bundle, priority service, or eligible ticket.
How strict is American Airlines?
American Airlines publishes 55 x 35 x 22 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.
