I do realize that. I don't agree with the utilitarian viewpoint on this one. You're saying that every single person on that other flight was more important that this guy.
A person on a completely different flight should not be affected by the airline's poor planning.
Skeds, try harder. Plan X amount of seats for deadheads. Don't need them? Fill them with standby passengers.
No, I'm saying that 1 (or 4) people chosen randomly to be delayed is better than the hundreds of people affected by a flight being canceled for lack of crew.
And "skeds trying harder" is not going to fix this. Surely you understand that unexpected things happen in aviation ALL THE TIME. And everyone paying significantly more for every flight so we can have empty seats and avoid the 1 in 20000 chance of being involuntarily bumped (and compensated) is just stupid. You're literally arguing for less efficiency.
