Carry-On Bag Requirements
Carry-on bags for United must fit in the overhead bin and measure up to 22 x 14 x 9 inches, including handles and wheels. Larger bags typically require checked transport, except for those qualifying for fare rules with expanded cabin baggage allowances.

FAQ
Reader questions
How can I confirm whether my bag is allowed as a carry-on on United?
Check the United website or app for the most current size limits, compare your bag against the 22 x 14 x 9 inches carry-on and 18 x 14 x 8 inches personal item specifications, and use the online bag tool before packing.
Will United board passengers with slightly over-limit carry-on bags?
United typically enforces measurements at the gate, and bags that exceed allowed dimensions may be checked at no cost if space is available, or charged if additional handling is required.
Do basic economy tickets on United ever include free carry-on bags?
Basic economy generally allows only a personal item for free; a carry-on bag usually requires an add-on purchase or qualifying fare, so review your ticket details before travel.
How do regional United flights handle smaller overhead bins?
On regional jets, bins are narrower, and enforcement is stricter; if your carry-on does not fit vertically, you may be asked to check it at the gate even if other United flights accept similar bags.
