You can change a JetBlue flight through the airline's website, app, or phone line, but the cost and restrictions depend on your ticket type and how far ahead you book the change

JetBlue allows you to change your flight without a change fee on most ticket types, but you may owe the difference if your new flight costs more. The process takes a few minutes online or about 15 minutes on the phone. The key is knowing which ticket type you bought — Blue Basic fares have stricter rules than Blue Plus or Blue Extra — and whether your new flight is available on the date you want.

You do not need to call JetBlue to change most flights. The fastest route is the JetBlue website or mobile app, where you can see available flights and complete the change yourself in one session. If you need help or your flight is within 24 hours of departure, calling 1-800-JETBLUE (1-800-538-2583) is faster than waiting for a callback.

Key Takeaways

  • JetBlue does not charge a fee to change your flight, but you pay the fare difference if your new flight costs more.
  • Blue Basic tickets cannot be changed to a different date or time; you can only change the flight if JetBlue cancels or significantly delays your original flight.
  • Blue Plus and Blue Extra tickets can be changed to any available flight on any date, as long as you change before departure.
  • You can change your flight online through the JetBlue website or app, or by calling 1-800-JETBLUE if you need information.
  • If you change your flight within 24 hours of departure, you must call JetBlue by phone; the website will not allow the change.

How to change your flight online

Go to jetblue.com and select "Manage My Booking" in the top menu. Enter your confirmation number (the six-letter code in your booking email) and the last name on the ticket. Click "Change Flight" and you will see a list of available flights on the date you want to travel.

Select your new flight and review the fare difference. If the new flight costs more, you will pay the difference by credit card. If it costs less, JetBlue will issue a credit to your account for future travel. Complete the payment and your new flight is confirmed when ready. You will receive a new confirmation number by email.

The JetBlue mobile app works the same way. Open the app, tap "Trips," enter your confirmation number and last name, and follow the same steps to select and pay for your new flight.

What Blue Basic tickets can and cannot do

Blue Basic is JetBlue's lowest-fare ticket type. You cannot change the date or time of a Blue Basic flight unless JetBlue cancels your flight, delays it by more than three hours, or significantly changes the schedule. If any of those happen, JetBlue will offer you a new flight at no charge, and you can accept it or request a refund.

If you want to change your Blue Basic flight for your own reasons — a schedule conflict, a family emergency, a preference for a different time — you cannot do so. Your only option is to buy a new ticket at the current price and lose the cost of your original ticket.

What Blue Plus and Blue Extra tickets can do

Blue Plus and Blue Extra tickets give you the flexibility to change your flight to any date and any available flight. You can change as many times as you want before your flight departs, and JetBlue will not charge you a change fee. You will only pay if your new flight costs more than the original.

This flexibility applies to the outbound flight and the return flight separately. If you booked a round trip, you can change just the outbound, just the return, or both. Each change is handled independently.

Changing a flight within 24 hours of departure

If your flight departs within 24 hours, the JetBlue website and app will not allow you to change online. You must call 1-800-JETBLUE to make the change. Have your confirmation number and the last name on the ticket ready.

JetBlue's phone lines are busiest in the morning and early afternoon. If you are calling to change a flight that departs the same day, call as early as possible. Wait times are typically shorter before 9 a.m. Eastern time.

What happens if your new flight costs more or less

If your new flight has a higher fare, you pay the difference when ready when you complete the change online, or by phone when you call. JetBlue accepts all major credit cards and debit cards.

If your new flight has a lower fare, JetBlue issues a credit to your account. This credit is not a refund to your original payment method — it is a travel credit that you can use to book any future JetBlue flight. The credit does not expire as long as you use it before the original ticket's expiration date, which is usually one year from the original booking date.

Changing a flight you booked through a travel agent or third-party site

If you booked your JetBlue flight through a travel agent, Expedia, Kayak, or another third-party booking site, you may not be able to change it directly through JetBlue. Contact the site or agent where you booked instead. They will submit the change request to JetBlue on your behalf, though this usually takes longer than changing directly with JetBlue.

Some third-party sites allow you to change flights directly in their system. Check your booking confirmation email to see whether it came from JetBlue or from the third-party site. If you are unsure, call the site's customer service number first before calling JetBlue.

What to do if your preferred flight is sold out

If the flight you want is fully booked, you cannot change to it. JetBlue does not have a waitlist for changes. Your options are to choose a different flight on the same date, change to a different date when your preferred flight has available seats, or keep your original flight.

Flights often open up as other passengers cancel, so if you are flexible, you can try changing again in a few hours or the next day. There is no penalty for attempting a change and then canceling it if the flight you want is not available.

Frequently Asked Questions

Do I lose my money if I change my flight?

No. You do not lose the cost of your original ticket. If your new flight costs less, you receive a travel credit. If it costs more, you pay only the difference. If it costs the same, there is no additional charge.

Can I change my flight the day before it departs?

Yes, as long as your ticket type allows changes. Blue Plus and Blue Extra can be changed up until the moment of departure. Blue Basic cannot be changed for schedule reasons. You must call JetBlue by phone if your flight departs within 24 hours.

What if I change my flight and then want to change it again?

You can change as many times as you want before departure, as long as your ticket type allows it. Each change is treated separately, and you pay the fare difference each time. There is no limit to how many changes you can make.

Can I change my flight to a different city?

No. You can only change to a different flight on the same route — same departure city and same arrival city. If you want to fly to a different destination, you must buy a new ticket.

Will I get a refund if I change to a cheaper flight?

You will not receive a cash refund. Instead, JetBlue issues a travel credit to your account that you can use to book any future JetBlue flight. The credit is valid for one year from your original booking date.
