Did you miss your JetBlue flight and could not inform beforehand? When you are not present at the time of boarding the plane, you are marked as a no-show passenger and JetBlue no show policy applies to your ticket. The regulations differ for passengers with a refundable ticket and a non-refundable ticket under this policy. In case any passenger fails to inform the airlines about their delay, their ticket can be completely forfeited by the airline but if the customer lets them know in advance, the ticket may get the JetBlue missed flight refund in the form of money or future credits.
