JetBlue Carry On Size (2026)

JetBlue’s published carry-on size is 22 × 14 × 9 in (55.88 × 35.56 × 22.86 cm), including handles and wheels. 1 carry-on and 1 personal item are free on every fare, including Main Base (the current name for the restricted fare formerly called Blue Basic). There is no weight limit if you can lift the bag into the overhead. Personal item: 17 × 13 × 8 in under the seat.

This page follows JetBlue’s official carry-on bags help, Our Fares, and bag calculator (and its flights terms). Carry-on dimensions and fare inclusion are the stable facts on this page. Checked-bag prices are on our baggage fees page; always check jetblue.com again before you fly.

Free with every ticket: one carry-on within the size limit (22 × 14 × 9 in, or 55.88 × 35.56 × 22.86 cm) plus one personal item (17 × 13 × 8 in). That includes Main Base, JetBlue’s restricted fare. (Bookings made under the old Blue Basic name correspond to today’s Main Base fare.)

Paid: checked bags only. Within the U.S., Latin America, the Caribbean and Canada, prepaid off-peak prices are $45 for the 1st bag and $59 for the 2nd when added more than 24 hours before departure, with higher amounts within 24 hours of departure and on peak dates; the full table is on JetBlue baggage fees. Mosaic, JetBlue card, Mint, and military waivers are summarized there.

Unlike United Basic Economy on most domestic routes, JetBlue Main Base includes the free overhead carry-on, so you are not limited to a personal item on the cheapest fare.

• Gate space permitting. Agents may gate-check carry-ons on full flights even when your bag is within the size limit.
• Main Base naming. Main Base is the current name; Blue Basic is the former name.
• Bag Calculator cm typo. The calculator has shown carry-on width as 15.56 cm; treat that as a typo and use 35.56 cm from carry-on help until JetBlue fixes the calculator.
• Contract of Carriage PDF may be out of date. It may still cite the former Blue Basic name or older fee figures; rely on JetBlue’s current legal fees page and carry-on help instead.
• The two sizes are separate. Personal item is 17×13×8; carry-on is 22×14×9, and they are not interchangeable limits.
• JetBlue publishes L×W×H for cabin bags, not a 45-linear-inch carry-on rule.

1. Stay at or under 22 × 14 × 9 in (55.88 × 35.56 × 22.86 cm) and measure including wheels and handles.
2. Pack a true under-seat personal item (17 × 13 × 8 in or smaller) as backup if overhead bins fill up.
3. For checked bags, prepay more than 24 hours before departure when possible; see baggage fees.
4. JetBlue’s free Main Base carry-on is not the same as United Basic Economy (personal-item only on most domestic routes).

These are loose suggestions only: measure your packed bag before travel. Look for bags marketed as airline carry-on or “22×14×9” compliant that stay at or under JetBlue’s published 22 × 14 × 9 in (55.88 × 35.56 × 22.86 cm) including wheels and handles. Under-seat companions should stay at or under 17 × 13 × 8 in (43.2 × 33 × 20.32 cm).

When shopping, filter for bags of 22×14×9 in or smaller and measure them yourself.

What is the JetBlue carry-on size?

22 × 14 × 9 inches (55.88 × 35.56 × 22.86 cm), including wheels and handles. JetBlue does not publish a carry-on weight limit if you can lift the bag into the overhead bin. Use the cm from JetBlue’s carry-on help rather than the Bag Calculator’s width typo (15.56 should be 35.56).

Does JetBlue charge for carry-on bags?

No. One carry-on that meets the size limit plus one personal item is free on all fares, including Main Base.

Does JetBlue Main Base include a free carry-on?

Yes. One carry-on that meets the size limit plus one personal item are free on all fares, including Main Base (formerly Blue Basic). That differs from United Basic Economy on most domestic routes, which is usually personal-item only.

Can JetBlue still gate-check my free carry-on?

Yes for space. Gate agents may check bags when bins are limited. That is a space outcome for an otherwise free carry-on that meets the size limit, not a Main Base “carry-on is paid” rule.

What if my bag doesn’t fit the JetBlue size check?

Expect to check it (fees may apply; see baggage fees). Overhead is space permitting; full flights may gate-check bags even when they are within the size limit.

What is JetBlue’s personal item size?

17 × 13 × 8 in (43.2 × 33 × 20.32 cm), under the seat. Examples: purse, small backpack, briefcase, laptop; a pet carrier counts as the personal item. Full detail: JetBlue personal item.

Is JetBlue carry-on the same as Delta or United?

JetBlue uses the same common 22×14×9 size as Delta and United (JetBlue publishes precise cm 55.88 × 35.56 × 22.86). JetBlue’s advantage over United Basic Economy: free overhead on Main Base.
