JetBlue Baggage Allowance: Carry-On, Personal Item & Checked Bags
Flying with JetBlue? Check personal-item and carry-on sizes, checked baggage rules and route-specific allowances before you travel.

JetBlue allows one carry-on bag and one personal item on all fares. This includes JetBlue flights to and from the UK and Europe, making the cabin allowance relatively straightforward. The personal item can measure up to 43.2 × 33 × 20.32cm and must fit under the seat.
Cabin baggage is one of the first things to check before travelling with JetBlue, because the number of pieces, permitted size and weight can differ by fare or travel class. The current allowance is summarised as follows: Free Cabin Bag Size 1 personal item up to 43.2 × 33 × 20.32cm 1 carry-on up to 55 × 35 × 22cm on all fares.. Your smaller personal item, where permitted, should be suitable for stowage beneath the seat, while the main cabin bag must fit safely in the overhead locker.
Checked baggage with JetBlue also depends on the ticket you have purchased rather than simply the destination. The current headline allowance is: Checked Baggage Allowance Standard checked bag: up to 22Kg and 158cm total dimensions. First checked bag is included on transatlantic routes.. Lower-cost or light fares can exclude checked baggage altogether, while flexible and premium fares often provide a larger allowance. Always check the baggage entitlement attached to the individual booking before packing.
Size and weight are separate limits. A suitcase can be within the permitted dimensions but still be overweight, or it can be light enough while exceeding the airline's dimensional limit. Additional Baggage Fees Checked bag fees vary by route and fare; overweight, oversized and additional bags cost extra.. Additional, overweight or oversized baggage can therefore attract extra charges or different handling requirements.
Cabin baggage must also comply with airport-security and dangerous-goods rules, which are separate from JetBlue's own baggage allowance. Liquids, gels, pastes and aerosols may be subject to the familiar 100ml container restrictions depending on the departure and connecting airports, while power banks and spare lithium batteries normally need to remain in cabin baggage rather than being packed in the hold.
This guide explains JetBlue's cabin and personal-item rules, checked-baggage allowances, fare and travel-class differences, liquid restrictions, additional and excess baggage, and the practical points most likely to cause problems at the airport. If another airline operates part of your journey, check that carrier's rules as well because allowances can differ across a multi-airline itinerary.

Key JetBlue Baggage Tips
A standard checked bag can weigh up to 22.68kg (50lb).
Checked bags must not exceed 158cm (62in) in total linear dimensions.
JetBlue states that the first checked bag is included on transatlantic routes.
Check the allowance on your JetBlue booking before you pack. Fare, cabin and route differences can materially change what is included.
Measure bags externally, including wheels, handles and protruding pockets, rather than relying only on the manufacturer's stated suitcase size.
Weigh cabin and checked baggage at home. A bag can be within the size limit but still attract charges if it exceeds the permitted weight.
Keep the personal item genuinely small enough to fit beneath the seat if the airline requires under-seat stowage; do not treat it as a second full-size cabin bag.
If you already know you need extra checked baggage, add it before reaching the airport where the airline offers advance purchase; airport excess-baggage charges can be higher.
Where standard airport liquid rules apply, the container size matters: a partly used bottle larger than 100ml can still be rejected at security.
Pack full-size toiletries in checked baggage when appropriate, while keeping medication and anything needed during the journey accessible in the cabin.
Keep power banks and spare lithium batteries in cabin baggage, protected against short circuits, rather than placing them in the hold.

Checked baggage with JetBlue: what you need to know
JetBlue's standard checked-bag size limit is 158cm (62in) when length, width and height are added together, with a standard maximum weight of 22.68kg (50lb).
Checked baggage inclusion depends on the route, fare and any Mosaic or eligible cardholder benefits. JetBlue states that the first checked bag is included on all transatlantic routes.
Additional, overweight or oversized bags are subject to extra fees. Because charges can vary by itinerary, use JetBlue's bag calculator or the baggage details shown in your booking before travelling.
If you are travelling on a connecting itinerary involving another carrier, check which airline's baggage rules apply to each sector.
JetBlue's checked-baggage entitlement can depend on the fare, travel class, route and the airline operating each sector. The allowance shown on your ticket or booking confirmation should therefore be treated as the final reference.
If your included allowance is not enough, additional baggage can usually be added where the airline offers this service. Arranging extra baggage before travel is generally preferable to discovering an excess at check-in.
A bag that exceeds the permitted weight, dimensions or number of pieces can be treated as excess, overweight or oversized baggage. Separate charges or handling restrictions may apply, and very heavy items may need to be repacked or carried as cargo.
For journeys involving another airline, do not assume the same checked-baggage rules apply throughout. Codeshare and interline itineraries can be governed by the operating carrier or the most-significant carrier under the applicable baggage rules.
Before travelling, check the baggage allowance attached to your specific JetBlue booking, particularly if you have changed your ticket, upgraded your cabin or added a connecting flight.
JetBlue cabin baggage rules: liquids, extras and restrictions
JetBlue allows every customer one carry-on bag and one personal item.
The personal item must fit under the seat and can measure up to 17 × 13 × 8 inches, equivalent to approximately 43.2 × 33 × 20.32cm.
The carry-on bag can measure up to 22 × 14 × 9 inches, approximately 55.88 × 35.56 × 22.86cm, including wheels and handles.
JetBlue does not set a published carry-on weight limit, but you must be able to lift and stow the bag safely.
For UK departures, airport-security liquid rules apply separately from JetBlue's baggage rules, so toiletries and liquids must comply with the requirements at the airport you are using.
Cabin baggage must be small and light enough to be safely stowed in the overhead locker or, for a personal item, beneath the seat in front. Published measurements normally include wheels, handles and other protruding parts unless the airline explicitly states otherwise.
For journeys departing the UK, liquids, gels, pastes and aerosols are subject to the security rules at the departure airport. Where the standard 100ml rule applies, individual containers must normally hold no more than 100ml and be presented in the permitted transparent resealable liquids bag.
Typical products affected include toothpaste, deodorant, shampoo, conditioner, shower gel, sun cream, skincare and cosmetics. Medication, baby food and certain medical items can qualify for security exemptions when required for the journey, although supporting evidence may be requested.
Power banks and spare lithium batteries should be carried in cabin baggage rather than checked baggage and protected against short circuits. Other dangerous or restricted items can be prohibited entirely or limited to either cabin or checked baggage.
JetBlue staff or airport handling agents may check cabin baggage at check-in or the gate. A bag that exceeds the permitted number, size or weight can be placed in the hold and additional charges may apply.

Using a personal item that is too large to fit beneath the seat
Packing liquids in containers larger than 100ml where standard airport restrictions apply
Assuming a partly empty large liquid container is security compliant
Packing power banks or spare lithium batteries in checked baggage
Ignoring different baggage rules on a partner-operated or connecting flight
