NO, ... THINK ABOUT IT -ITS NOT AS SIMPLE AS “THE AIRLINE JUST WANTED TO FLY SOMEONE ELSE”
If you are flying from A to B, and there is another flight from C to B that is cancelled due to weather or mechanical or whatever, then the airline may need to move a pilot and crew to B to replace the crew from C that could not make it there.
Otherwise hundreds of people at B may get stranded or delayed, and then thousands as that cascades outwards to other airports.
So.. it is simple- remove 4 people now, or have cascading problems outwards...
