I have a ticket for a Sunday morning early flight from MIA-BOS-LGA. I am hoping that I can standby for a flight that is later in the day, perhaps a direct route from MIA-LGA. What are my options to standby for later flights? I have only used the process of standby for earlier flights. What would happen if, despite my status, I am unable to get on a standby flight after my own? Also, how do I go about listing myself for a later standby? Many thanks my friends.
