There is one of these threads every month or so. They are all the same and hopefully they'll sooner or later be merged.

Maintenance cancellations & delays are based on binary decisions, not what somebody thinks is important. There is the engine dropping off the wing and there is also the OH bin which can't be closed.

If the bin can't be closed, it has to be repaired. If it is simply not operational, it can be closed and sealed. All it takes is some fool who dragged a steamer trunk onboard on the preceding flight and loused up the mechanism.

Would be great if this stuff didn't happen, but it does. And when it does, the repair is mandatory if it's mandatory and not if it's not (for the contemplated trip).
