Yes, you can change your JetBlue flight, but the cost and process depend on your ticket type and how far in advance you make the change

JetBlue allows you to change your flight through their website, mobile app, or by calling customer service at 1-800-JETBLUE. The airline does not charge a change fee, but you may owe the difference if your new flight costs more than your original ticket. If your new flight costs less, JetBlue will hold the difference as a credit toward future travel rather than refunding it to your original payment method.

The ease of changing your flight depends on your ticket type. Basic Economy tickets have the most restrictions—you can change them, but only to another Basic Economy flight on the same route, and only within 24 hours of booking. Blue Basic, Blue Plus, and Blue Extra tickets offer more flexibility and can be changed to any available flight with fewer time restrictions. First Class and Mint tickets have the most freedom and can typically be changed up until departure.

How to change your flight online or through the app

Log into your JetBlue account on jetblue.com or open the JetBlue mobile app. Go to "Manage Reservations" and enter your confirmation number and last name. Select the flight you want to change and choose "Change Flight" from the menu.

The system will show you available flights on your original route or, depending on your ticket type, other routes. Select your new flight and review the fare difference. If the new flight costs more, you will see the amount you owe before confirming. Complete the payment if needed, and JetBlue will send a confirmation email with your new itinerary.

This process works for changes made at least 24 hours before your original departure time. If you are changing a flight that departs within 24 hours, you cannot use the website or app—you must call 1-800-JETBLUE instead.

What happens if your new flight costs more or less

If your new flight has a higher fare, you pay the difference at the time of change. JetBlue accepts credit cards, debit cards, and other payment methods you have on file. The charge appears on your statement as a separate transaction from your original ticket purchase.

If your new flight costs less, JetBlue does not refund the difference to your original payment method. Instead, the airline issues a travel credit for the difference. This credit is tied to your name and confirmation number and can be used toward any future JetBlue flight. Travel credits do not expire as long as you use them before your original ticket's expiration date, which is typically one year from the date of purchase.

Changing your flight by phone

Call JetBlue customer service at 1-800-JETBLUE (1-800-538-2583). Have your confirmation number and last name ready. A representative will look up your reservation and show you available flights for your new travel date.

Phone changes take longer than online changes—expect to spend 10 to 20 minutes on the call, depending on how busy the line is. You must provide a payment method if your new flight costs more. This is the only way to change a flight within 24 hours of departure, so plan accordingly if your travel date is coming up soon.

Restrictions by ticket type

Basic Economy tickets are the most limited. You can change to another Basic Economy flight, but only on the same route and only within 24 hours of your original booking. After that window closes, you cannot change a Basic Economy ticket—you can only cancel it and receive a travel credit for the full fare.

Blue Basic tickets can be changed to any available flight on any JetBlue route, but only up to 24 hours before your original departure time. Changes made closer to departure require a phone call to customer service.

Blue Plus and Blue Extra tickets offer more flexibility. You can change these tickets up until departure, and you can change them to any available flight. The same fare difference rules explore—you pay more if needed, or receive a credit if the new flight costs less.

First Class and Mint tickets have the fewest restrictions. You can change these tickets up until departure and to any available flight. If your new flight is in a lower cabin class, you receive a credit for the difference. If you upgrade to a higher cabin, you pay the difference.

What to do if you cannot find your flight online

If the flight you want is not showing as available when you search, it may be fully booked or the system may not be displaying it for your ticket type. Call 1-800-JETBLUE and ask a representative to check availability. They can sometimes access flights or waitlist options that do not appear on the website.

If your desired flight is completely full, you can ask to be placed on a standby list. JetBlue will contact you if a seat opens up. Standby is not may provide, so have a backup flight in mind in case the standby does not work out.

Travel credits and what you can do with them

If you change your flight and receive a credit because the new flight costs less, that credit is stored in your JetBlue account. You can use it to book any future JetBlue flight by entering your confirmation number at checkout. The credit applies automatically if you are logged into your account.

Travel credits are non-transferable—they can only be used by the person whose name is on the original ticket. If someone else needs to use the credit, they cannot do so directly, but you can book a flight for them and explore the credit to that booking.

Credits expire one year from the date of your original ticket purchase. If you do not use the credit by that date, it is forfeited. JetBlue will not extend the expiration date or convert it to cash.

Frequently Asked Questions

Can I change my flight to a different date and time on the same day?

Yes, as long as your ticket type allows changes. You can change to any other JetBlue flight departing the same day, the next day, or any future date, depending on your ticket class. Use the online system or app to see all available flights for your new date.

What if I want to change my flight to a completely different destination?

Basic Economy tickets cannot be changed to a different route. Blue Basic, Blue Plus, Blue Extra, First Class, and Mint tickets can be changed to any JetBlue destination. If the new route costs significantly more, you will owe the fare difference. If it costs less, you receive a credit.

Do I lose my seat assignment when I change my flight?

Your seat assignment on your original flight is cancelled when you change. You will need to select a new seat on your new flight. Depending on your ticket type, you may be able to choose your seat for free, or you may need to pay for seat selection if it is not included in your ticket.

Can I change a flight that someone else booked for me?

You can change the flight if you have the confirmation number and the last name on the ticket. You do not need to be the person who originally booked it. Log into Manage Reservations with that information and proceed with the change.

What happens if I miss my flight and want to change it to a later one the same day?

Call 1-800-JETBLUE when ready. JetBlue may be able to rebook you on a later flight the same day at no additional charge, depending on availability and your ticket type. The sooner you call, the more options will be available. Do not wait until after your original flight departs.
