Here is a copy of the email Jetblue sent me explaining in detail about the new reservation system conversion:
Next Friday, January 29, JetBlue will begin transitioning to a new reservation system. Although the new system will allow us to better serve our customers, the conversion is complex. As a result all of our reservations, booking and TrueBlue services will be unavailable from
12 p.m. EST on Friday, January 29 to Saturday afternoon, January 30.
This is how you will be affected during this time:
TrueBlue
You will be unable to access your TrueBlue account, book flights or make any changes to flights on jetblue.com or 1-800-JETBLUE.
TrueBlue points may not appear in your account for up to ten days after you travel.
If you need to book an Award Flight or make changes to your itinerary, please do so before or after this period.
jetblue.com
You will be unable to book flights or make changes to reservations. If your matter is urgent and you need to book a flight or make changes to flights during this period, you can do so only at the airport.
Flight status will be unavailable.
Online check-in will be unavailable.
1-800-JETBLUE
Reservation agents will be unable to book flights or make changes to reservations. If your matter is urgent and you need to book a flight or make changes during this period, you can do so only at the airport.
Airports
Check-in and bag-drop lines will be longer during and immediately after the transition.
We recommend that you arrive at the airport:
two hours before your scheduled departure for domestic flights.
three hours before your scheduled departure for international flights.
Thank you for your understanding and patience as we make this important change to our business systems.
Sincerely,
JetBlue Airways
