JetBlue allows passengers with large groups to travel on the same flight with one booking, but they have to follow the rules for it. Travelers must have 10 or more passengers in the group, bookings should be made prior, and some other rules apply. To book a JetBlue Group Travel flight, you can visit the official website or speak to a professional in the dedicated group travel department. If you need assistance with group travel flights, you can contact JetBlue customer service or read the blog by Airlines Group Travel at the mentioned link.
