Yep, made a nuisance of myself a few times on board.
1. Missing life jacket. Fortunately there was an empty seat next to me so I "moved" to that seat for take off as we were taking off over water.
2. Unusual sound coming from a window. Cabin crew reported it to the Flight Deck, it was presssurising normally and the sound eased off.
3. Ice on the wings. Transaero B737, just before Xmas many years ago. I reported it to the cabin crew. The flight deck "ignored" it. Obviously no crash as I am here to tell the tale. Pax around me were wondering why I was getting a bit upset. This was just after Aeroflot took off with wings covered in snow. All other western airlines were being de-iced on stand. As we taxied off, I thought, ok, remote de-ice. Nope. We departed! I was genuinely concerned.
The crew report was pretty scathing but what really pissed me off was our company's response! I can't say anymore but I did get stuck into the director of safety a few years later about that response. I refused Russian based airlines after that.
One of the responses was "well, you should have just got off". Riiiiiiiiight. A western female demanding to get off whilst taxiing. I'd still be in gaol....
4. A pax was showing signs off aural distress (baro trauma) at the Top of Descent. He and his wife didn't want to cause a fuss. I said that it won't get better, it will get much much worse. Pressed the callbell, explained the situation and resolved very quickly without further issue.
