Have you been declared as a no-show passenger on a JetBlue flight? Under certain circumstances, it is possible for a passenger to get later than the flight’s departure time, such passengers are considered no-show passengers. According to the JetBlue no-show policy, if a traveler was late due to serious reasons like medical emergencies, and arrives within 2 hours from the time, he is eligible for the allotment of a standby flight. Stand-by flights, if available, are allotted on a first-come, first-served basis and a certain fee is charged from the buyer if his reason was anything other than medical issues.
