Do you want to enquire about the fee for getting a JetBlue standby flight? When a passenger misses a flight they have to pay JetBlue missed flight fee to get rebooked for another flight but in case of severe reasons like medical emergencies, they get the allotment without having to pay any price. For this, the passenger must arrive prior to at least 2 hours after departure time. You are obliged to inform the airlines ahead of time when you make certain to fail to catch your plane or you can't come to arrive at the airport on time.
