There are a few reasons why you might not be able to check in for your JetBlue flight online. Here are some of the most common reasons:
Your flight is not yet available for check-in. JetBlue typically opens check-in 24 hours before your flight's scheduled departure time. If it's still too early to check in, you'll see a message on the website or app that says "Check-in not yet available."
Your flight is full. If your flight is full, you may not be able to check in online. You'll need to check in at the airport.
You have a fare that does not allow online check-in. Some JetBlue fares do not allow online check-in. If you have one of these fares, you'll need to check in at the airport.
There is a problem with your reservation. If there is a problem with your reservation, such as an incorrect name or an invalid credit card, you may not be able to check in online. You'll need to contact JetBlue customer service to resolve the issue.
When the passengers of JetBlue can’t check in then they can contact the airline's agents for assistance.
