ELI5: When weather cancels 2800 flights, and 50k people are displaced, how to they all get back on schedule since so many of the flights for the next few days are already booked up?

When 50K people can't get home due to cancellations, that means about 50K never left home due to cancellations.  A lot of those people are going to cancel their trips, or reschedule them a ways into the future.  Their seats become available to help the stranded get home.
