What is the JetBlue Check in International Flight Policy?

JetBlue requires passengers to check in for international flights no later than 60 minutes prior to departure. This deadline is strictly enforced, and passengers who do not check in by this time may be denied boarding.
JetBlue recommends that passengers arrive at the airport at least 3 hours before their scheduled departure, especially if they are checking bags. This will give passengers enough time to check in, go through security, and clear immigration. If you are traveling to or from Cuba, the recommended check-in time is 4 hours before departure.
There are three ways to check in for an international flight with JetBlue: online, through the JetBlue app, or at the airport. If you check in online or through the app, you can print your boarding pass or have it sent to your mobile device.
