I’d like to know why the flights were canceled yesterday
On the whole Earth?
We are not in your head, you need to give more details. And usually it’s better to ask that at the specific airline that canceled.
I don’t have more details just the airport
The flight was canceled yesterday because the pilot decided he would rather stop by his local brewery rather than do touch and go’s all afternoon.
Are we supposed to guess that airport? And then guess the flight? And then provide an explanation of why?
I did a search for Drunk Pilot.
Possibly this American Airlines pilot arrested shortly before take-off on suspicion of being drunk is what he is referring to.
