Jetblue Airlines

JetBlue is a low-cost airline that operates out of the United States and has its headquarters in the Long Island City area of Queens in New York City. Additionally, it has administrative locations in the state of Utah as well as the state of Florida. JetBlue operates more than 1,000 flights daily and provides service to 100 domestic and international network locations in the United States, Canada, Mexico, the Caribbean, Central America, South America, and Europe. Although JetBlue is not a member of any of the three major airline alliances, the company has codeshare agreements with 21 other airlines, some of which are also Oneworld, SkyTeam, and Star Alliance.

Carry-on Bags

All fares include one personal item that fits under the seat in front of you. This could be a purse, daypack, laptop bag, or approved pet carrier. Personal items cannot exceed 17" L (43.2 cm) x 13" W (33 cm) x 8" H (20.32 cm).
In addition, all Blue, Blue Plus, Blue Extra, and Mint fares include a carry-on bag that fits in the overhead bin. Including wheels and handles, carry-on bags must not exceed 22" L (55.88 cm) x 14" W (35.56 cm) x 9" H (22.86 cm). For customers who purchased a Blue, Blue Extra, or Mint fare on domestic flights within the U.S. (or who purchase an Even More® Space seat—for all legs, if connecting), the carry-on bag will make it on board, as long as it meets all the requirements. For other routes, overhead bin space is first come, first served, based on availability. Those in later boarding groups may be required to gate-check their carry-on bags.
Blue Basic fares do not allow a carry-on bag. Any carry-on bag brought to the gate (aside from a personal item that fits under the seat in front of you) will incur a fee and need to be checked. The fee is $65 (if it would be your 1st or 2nd checked bag) or $180 (if it’s your 3rd).
The only exceptions are:
Mosaic members (who get a carry-on bag and early boarding with all fares)
Travelers to/from London (including connecting flights)
Travelers that are combining a Blue Basic fare with an Even More® Space seat (on all legs, if connecting)
Active U.S. military
Unaccompanied minors
Please note, of the above exceptions, only Blue Basic customers who purchase an Even More® Space seat (on all legs, if connecting) are guaranteed to get their carry-on bag on board.

Those who have added a pet to a Blue Basic booking can board with a personal item and their approved pet carrier. Customers who purchase an extra seat may check additional bags based on the fare option for that extra seat. Per the FAA, the allowance for personal items and carry-on bags does not increase, as these are calculated per person and not per seat.

Checked Bags

You’re always welcome to check bags to your destination. You can add up to 2 checked bags anytime, from during the booking to when you arrive at the airport. If your fare does not include checked bags, you’ll save money by purchasing them in advance on jetblue.com or the JetBlue app.
Before you pack, ensure your bags meet our checked bag size, dimensions, and weight requirements. Checked bags exceeding 62" (157.48 cm) in overall dimensions (length + width + height) or 50 pounds (22.68 kg) will also incur a fee.
If you’re traveling internationally, see Bag Limitations for Select Markets.
Mosaic members flying on American-operated flights and AAdvantage elite members flying on JetBlue-operated flights are entitled to up to 2 free bags at check-in time.

Online Check-in

To utilize Remote Check-in, you must check in at a JetBlue property that offers Remote Check-in at least two to four hours before your flight (depending on the location). You can check in for your flight and leave your luggage off to be tagged and sent directly to the airport so that they can be boarded on your aircraft for a ticket that ranges anywhere from $10 to $20, depending on where you are located. After providing you with a boarding card and bag tags, the BAGS agent will collect your luggage and transport it to the airport. It is a safe, simple, and rapid method.

Additional Information

Words and phrases such as "Unbelievable" and "We like you, too" were included in JetBlue's very first extensive advertising campaign. Newspaper adverts that took up an entire page bragged about affordable tickets, new planes, leather seats, ample legroom, and a customer-service-oriented workforce dedicated to "bringing humanity back to air travel." The first airline to provide individualized in-flight entertainment for all passengers, JetBlue pioneered this service. Customers had live access to over 20 DirecTV channels through the flat-screen monitors in every seatback in April of 2000. There was no additional charge for this service.
