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.
JetBlue publishes 55 x 35 x 22 cm for the cabin bag, and at the gate the sizer frame decides — not your tape measure. CabinFit does not publish an enforcement score; a bag within 1 cm of any limit leaves almost no packing margin. Hard shells can't squeeze and soft bags bulge once packed — leave yourself a margin.

context
JetBlue is a low-cost carrier based in United States. Like most low-cost carriers, the free allowance is usually just the underseat bag — the larger cabin bag is often a paid add-on, so match your bag to your exact fare before you get to the gate.
Special travel items
Only source-backed policies are expanded. Missing categories stay in a compact review state instead of being presented as airline facts.

JetBlue publishes 43 x 33 x 20 cm for the personal item, which rides under the seat in front of you, and 55 x 35 x 22 cm for the carry-on, which goes in the overhead bin. Your fare decides whether one or both are included.
No. CabinFit compares your measurements with the limits JetBlue published (JetBlue carry-on bags, last checked Aug 9, 2026). Gate staff, fare conditions, and aircraft changes can still affect the final decision — keep a margin and open the official page before you fly.
