Nope. I have no association whatsoever with QA. I am not even airline staff for another airline.

I have flown numerous flights over the years though, encountered a fair few delays, lost luggage and so on (in fact, now I try to always take carry on only, I really don't like to check luggage in).

It's just common sense really: if there's some kind of delay, or if the flight is overbooked, shouting aggressively 'what the hell is happening?' at an airline official who you've just met isn't going to resolve the situation. No point whatsoever.
