If your travel plans change on the day of departure, JetBlue may allow you to move to another flight through a same-day switch or same-day standby.
Eligibility depends on your fare, route, airport, flight availability, and whether you are requesting a confirmed switch or standby.

What Is a JetBlue Same-Day Flight Change?
A JetBlue same-day flight change lets an eligible passenger move to another flight on the same calendar day as the original reservation.
Instead of changing your trip to another date, you keep the same travel day and move to another eligible departure.
For example:
Original flight: 6:30 PM
Preferred flight: 2:00 PM
If your ticket qualifies and an eligible seat is available, you may be able to make a same-day switch.
When Can I Request a JetBlue Same-Day Change?
JetBlue says same-day switches can generally be requested after midnight on the calendar day of travel.
The replacement flight must meet JetBlue's same-day requirements. You cannot normally use a same-day switch simply to move your ticket to tomorrow or another future date.
If you want to move your trip to another day, use JetBlue's regular flight-change process instead.
How Much Is the JetBlue Same-Day Flight Change Fee?
The fee depends on the fare and benefits attached to your reservation.
JetBlue's published optional-fee information currently lists a $75 per-person same-day switch fee for several fare categories, while certain fares and eligible Mosaic benefits can provide the switch without that fee.
JetBlue has also introduced a new Base, Standard, and Flex fare structure in 2026, so the fare terms shown on your actual reservation should be treated as the controlling conditions.
Always review the fee displayed before confirming the switch.
Do I Have to Pay a Fare Difference?
An eligible JetBlue same-day switch is different from a normal voluntary flight change.
JetBlue's published same-day switch rules state that an eligible same-day switch does not require payment of the normal fare difference.
This can make a same-day switch useful when another flight on the same day is selling for significantly more than your original ticket.
However, the applicable same-day switch fee can still apply depending on your fare and status.
Can I Switch to an Earlier JetBlue Flight?
Yes, an eligible same-day switch may allow you to move to an earlier flight.
For example:
Original flight: 7:00 PM
Earlier flight: 1:30 PM
Check availability through your reservation or contact JetBlue to see whether the earlier flight qualifies.
Can I Switch to a Later JetBlue Flight?
Yes, eligible confirmed same-day switches may also allow you to move to a later flight on the same travel day.
For example:
Original flight: 11:00 AM
Preferred later flight: 5:00 PM
The later flight must still meet the applicable JetBlue same-day rules and have eligible availability.
What Is JetBlue Same-Day Standby?
Same-day standby means you wait for an available seat instead of receiving a confirmed seat immediately.
JetBlue's standby rules are more restrictive than a confirmed switch. Standby typically applies to an eligible flight immediately before your originally scheduled departure.
Being placed on standby does not guarantee that you will receive a seat.
Same-Day Switch vs Same-Day Standby
A same-day switch gives you a confirmed seat on another eligible flight.
Same-day standby places you on a waiting list and you only travel if a seat becomes available.
If reaching your destination at a specific time is important, a confirmed same-day switch is usually more predictable than standby.
Can I Change My Departure or Destination Airport?
A normal same-day switch generally needs to keep the same origin and destination.
Changing to a completely different city or route is usually treated as a regular itinerary change rather than a simple same-day switch.
Nearby-airport flexibility may sometimes be offered during airline disruptions, but that is a separate policy from a voluntary same-day change.
Can I Make a Same-Day Change Through a Travel Agency?
JetBlue states that same-day switches must be completed directly with JetBlue rather than through an agency.
If your original ticket was purchased through another travel website or agency, you may still need to contact JetBlue directly for the same-day switch itself.
Can Mosaic Members Get Free Same-Day Changes?
JetBlue provides additional same-day travel benefits to eligible Mosaic members.
The exact benefit can depend on current Mosaic rules, fare conditions, and reservation details, so check the benefits attached to your TrueBlue account before paying a same-day fee.
What If My JetBlue Flight Is Delayed?
Do not automatically use a voluntary same-day switch if JetBlue has significantly delayed your flight.
A qualifying airline disruption can provide better rebooking or refund options than a normal voluntary same-day change.
Check Flight Tracker and Manage Trips first to determine whether JetBlue is offering disruption-specific rebooking.

Frequently Asked Questions
Final Word
A JetBlue same-day flight change can be useful when you need an earlier or later flight without moving your trip to another date.
Check your fare eligibility first, compare a confirmed same-day switch with standby, and review the applicable fee before confirming the new flight.
If your original flight has been significantly delayed or cancelled, check JetBlue's disruption options before making a voluntary same-day change because you may qualify for different rebooking or refund benefits.
