What Are JetBlue’s Baggage Restrictions?

When you fly with JetBlue you get to bring a carry-on and a personal item free of chargeAs long as these items are within the airlines’ size limitations, you can bring these two items on without issue. If you need assistance devices or child-care items, those you can bring on without them counting towards your carry-on allowance.

Exceeding the sizing limitations for JetBlue means you will be charged a fee or denied if they are too large. To make sure you do not run into this problem, measure your luggage before going to the airport.

 Your checked bags should not exceed 62” linear inches (157.48 linear centimeters) in their dimensions. Otherwise, they will be considered oversized. These bags should also not exceed 50 pounds (22.68 kg), or they will be overweight. 

If your checked bag is too big in dimensions you will have to pay a $150 fee. The oversized dimensions are between 63-80 inches or 160-203 centimeters. Overweight bags are those between 51 and 99 pounds or 23 to 45 kilograms.

However, if your bag is overweight and oversized, you will need to pay both the overweight fee and the oversized fee. And if your bag is over 80 linear inches or 99 pounds, it will not be accepted onto the plane.

To quickly summarize JetBlue’s baggage restrictions, you are allowed a free personal item and a carry-on bag with each ticket. Your carry-on must not be larger than 22″ x 14″ x 9″. Otherwise, you will have to pay $35 to check it under the plane. 

Checked bags must not be larger than 62 linear inches or 50 pounds, otherwise, you will face steep oversized fees. And if your checked bag is over 80 linear inches or 99 pounds, it will not be accepted at all. 

What Are The Size Limitations For JetBlue?

Sizing standards for JetBlue are very standard for the industry and can apply to pretty much every airline. You will see the phrase ‘linear inches/centimeters’ a lot when reviewing sizing limitations so different kinds of bags can be used for travel. Linear inches or centimeters are found by adding up the length, width, and height of your bag. As long as the sum of these numbers doesn’t pass the linear limit, it is approved by JetBlue!

Carry-on size limitations are quite strict on JetBlue Airlines. An oversized carry-on can take space away from other passengers and cause problems for the flight. Your carry-on should not exceed the measurements of 22″ x 14″ x 9″ or 45 linear inches altogether. There will be measurement bins around the airport to make sure your bag can fit, but it is best to measure beforehand to avoid any issues.

Personal items are less regulated on airlines as the primary rule is they should be able to fit underneath the seat in front of you. If you are worried about your personal item being too big, measure it! A personal item on JetBlue should generally not exceed the measurements of 17″ x 13″ x 8″ or 38 linear inches. Typically a standard backpack, purse, briefcase, or laptop bag can fit in these dimensions without a problem.

For checked bags, you want to make sure the luggage does not exceed 62 linear inches or 157.48 linear centimeters. You will likely face steep oversized fees if your bag is larger than this. It is best to be safe and measure your luggage before you leave. These limitations are very strict with JetBlue Airlines. It is better to be safe than sorry and take the time to measure your luggage!

What Are The Weight Limitations For JetBlue?

There is no official carry-on weight limit for JetBlue Airlines! You will not run into any scales before going onto your flight. However, the general rule of thumb is to keep the weight under 50 pounds.

This is because you will need to live your carry-on over your body to place in the overhead bins. So it is best to keep the packing light so there is not struggle during boarding. But if you pack the typical clothes and toiletries you are unlikely to get near 50 pounds.

For checked bags, you can not exceed 50 pounds (22.68 kg) in weight to only pay $35. Even if your luggage is 51 pounds, you will have to pay an extra $150 to check the bag. If your bag is over 99 pounds, it will not be checked onto the plane at all. If you are worried about the weight, simply measure the bag with a scale at home.

What Is Not Allowed In a Carry-On For JetBlue?

JetBlue Airlines follows the TSA restrictions for carry-on liquids, gels, and aerosols. These substances are only allowed in containers with a maximum size of 3.4 ounces (100 milliliters). All containers also must fit into a single, sealable clear quart-size plastic bag. Anything over these restrictions is not allowed in their carry-on.

Drugs such as tobacco, alcohol, marijuana, or e-cigarettes are not allowed in your carry-on. Other more obvious items such as firearms and explosives will not make it through TSA and onto a JetBlue Airlines flight. Some lesser-known items you can not bring are pepper spray, hoverboards, lithium batteries, bleach, or any form of lighters.

Since these items are not allowed in your carry-on, they are also not allowed in your personal item. It is always best to make sure your liquids are in TSA-approved bottle sizes and there are no hazards in your luggage. Items such as a corkscrew or a screwdriver can be flagged, so be thorough!

If you happen to pack one of these banned items, you will likely get flagged at TSA and they will confiscate the items. JetBlue Airlines baggage restrictions align with those of TSA. So even though the airline itself does not take these items from you, TSA will do so on their behalf. Accidents do happen, so if you forget one of the minorly banned items in your bag you will likely not be punished.

How Many Carry-Ons Can I Bring On JetBlue?

Regardless of your ticket, you will only be allowed to bring on a single carry-on item with you onto the JetBlue Airlines plane. Too many carry-ons stuffed into the overhead bins on the plane could cause them to suddenly open during the flight and fall onto the heads of other passengers. So never plan to bring more than one carry-on item per passenger.

Beyond the carry-on item and personal item, you will not be allowed to bring anything else onto the plane. If you have special items like strollers or wheelchairs, those may need to be checked. There are some items you are allowed to bring on and will not count towards your carry-on allowance. Regardless of its special status, you can often check these items at the gate rather than at the ticket counter so you can use them at the airport. Be sure to communicate at the ticket counter or review the JetBlue website to understand these special cases better.

If you need to check bags, your first bag will be $35 and the second with be $45. If you purchase a special ticket you may have a checked bag included in the price. For basic tickets, you will have to pay $35 to check a bag within the size and weight limitations.

You are always allowed to bring a personal item on the plane. This includes items such as backpacks, purses, pillows, laptop bags, jackets, and other small items. The personal item must be small enough to fit underneath the seat in front of you. Meaning it can not be another small suitcase. To summarize, you are only allowed a single carry-on and a personal item on JetBlue airlines unless you have a special item that qualified otherwise.

Can I Bring a Purse and a Backpack On To JetBlue?

Generally speaking, you can absolutely bring a purse or backpack onto a JetBlue flight! These items tend to usually qualify as your personal item. Which makes it easy to keep at your feet during the flight. So long as the bag is not too large that it will not fit under the seat or bigger than 38 linear inches, you can certainly bring these bags along with you.

A traditional school backpack or simple purse fits perfectly in this space. You will run into problems if your backpack or purse is too large to fit under the seat in front of you. If you are looking to bring an extremely large backpack, such as one made for long hiking trips, that should be checked or used as a carry-on

If you are looking to bring a traditional purse or backpack with you onto a JetBlue Airlines flight, you will have no need to worry. Even larger than average backpacks and purses as be brought as personal items. But if it gets too large you could use the bag as your carry-on item or check it under the plane.

Does JetBlue Charge For a Carry-on?

JetBlue does not charge you to bring a carry-on onto your flight as long as it adheres to the sizing restrictions. Even if you have a basic economy ticket, you will not see any extra fees with your carry-on! This is a great perk with JetBlue and is perfect for small weekend trips where you do not need more than a few items. It is a part of why this airline is so affordable and great for budget travelers.

If you have special items that need to be with you at the airport or the flight, such as a diaper bag, wheelchair, stroller, or other assistive devices, then you can bring those as carry-ons without charge.

These items also will not count as your carry-on, so you will still be able to bring on a suitcase. If you are traveling with an item such as these, it is best to get in contact with JetBlue to be sure you will be accommodated during your travels.
