Being the sixth largest airline in the United States, JetBlue has left no stone unturned to provide passengers with an unmatched air travel experience. Whether it’s about the free wifi or the snacks & beverages on board, JetBlue has got you covered. But wait! What about its baggage policy? Is JetBlue’s generosity evident here? Let’s be specific: when you are traveling, you’ll carry stuff, if not in the checked luggage, indeed in the carry-ons, but you will.
So, thoroughly understand all there is to know about JetBlue Carry On Bag Size and be prepared to pack smart and light. Without beating around the bush, let’s begin.

Carry-On Rules: What Does It State?
Before you start packing your travel essentials, it’s crucial to know the exact size limits for carry-on luggage on JetBlue flights. Fortunately, JetBlue allows its passengers to bring one standard carry-on bag and one personal item aboard, provided both meet the specific size and weight criteria.
Standard Carry-On Allowance
JetBlue’s standard carry-on bag size is generous compared to many other airlines, which means you can carry more than you think, even when you are not bringing along checked luggage. The bag must not exceed the following dimensions:
- Dimensions of a Carry on Bag JetBlue: 22 inches (length) x 14 inches (width) x 9 inches (height)
- Carry on Bag Weight Limit JetBlue: Carry-on bags have no weight limit as long as you can lift and store the bag in the overhead compartment yourself.
The specific dimensions ensure that your carry-on fits well in the overhead bin without causing you any trouble during boarding. It’s always recommended to measure your carry on before you start packing because even an inch over the limit could result in the need to check your luggage.
Items that Fit as JetBlue’s Carry-On Bag
Most standard-sized suitcases, roller bags, and duffel bags fit within the JetBlue Carry On bag size limit. Precisely, a small to medium-size roller bag is the best option for you to adhere to the airline’s guidelines and still be able to carry your essentials.
JetBlue Personal Item Regulations
In addition to carry-on luggage, JetBlue passengers can bring one personal item onboard. Items that qualify as personal items can either be a laptop bag, briefcase, backpack, purse, or any other small piece of luggage. Make sure your personal item doesn’t exceed the following dimensions:
One personal item should not exceed 17 inches (length) x 13 inches (width) x 8 inches (height).
Your personal item must fit under the seat in front of you, as this is where it needs to be stored during the flight.
Note: Carrying a personal item along with carry-on luggage can maximize the space available for your travel essentials. If you are traveling on a budget and do not want to pay for checked luggage, this is your best way out. |
Carry-On Allowance for Passengers Flying with an Infant
If you are traveling with an infant on a JetBlue flight, it’s apparent that you will have a lot of baby items to carry, which is why you need to know that:
- Children aged up to two years can sit on the parent’s lap.
- Check your infant’s car set or stroller at no additional cost.
- You can freely carry diaper bags, personal items, and a carry-on.
- Assistive devices such as breast pumps aren’t included as a carry-on. Bring’em along.
JetBlue’s “Blue Basic” vs. Other Fare Classes: Carry-On Differences
If you are flying on a Blue Basic fare, you will encounter some restrictions when it comes to carry-on luggage. To avoid surprises at the airport, you must familiarize yourself with the same.
Blue Basic Fare Restrictions
The guidelines goes as:
- Carry-On: Blue Basic fare does not include a free carry-on bag (this only consists of a personal item. Nevertheless, you can still bring a carry-on by purchasing the allowance separately.
- Boarding Priority: Blue Basic passengers board last; there’s a possibility that overhead bin space could be limited, so consider boarding early or purchasing early check-in.
Upgrading to Blue, Blue Plus, or Mint
Blue and Blue Plus fares include free carry-on luggage, so you do not have to worry about paying additional costs for a bag. In addition, Mint passengers enjoy premium cabin privileges, including priority boarding, so you can store your carry-on luggage easily and make the most of the overhead bin space.
Tips for Packing Your Carry-On Bag for a JetBlue Flight
Efficiently packing your carry-on can save you a lot of trouble and space (needful at the moment). So, ensure that you have everything you need within reach. Here are some smart packing tips you can follow:
- Roll, Don’t Fold: Rolling clothes instead of folding them can save you ample space and prevent wrinkles.
- Wear Bulky Items: If you’re bringing bulky shoes or outerwear, wear them during the flight rather than packing them.
- Use Packing Cubes: These help compress clothing and maximize space in your carry-on, making it easier to organize your items and avoid overpacking.
- Pack Electronics in Easy-to-Access Locations: Laptops, tablets, and other electronics must be taken out during security screening, so make sure they’re easily accessible.
- Keep Liquids in Compliance: Remember that liquids must be in containers of 3.4 ounces or less and stored in a quart-sized, clear plastic bag. Make sure all your toiletries follow the TSA guidelines.
If you follow these tips, you can avoid exceeding the Carry on weight JetBlue. So, what is it that you want? Decide for yourself! This takes us to our next point.
