Wow...
I'm ALWAYS early at checkin for Standby, at least 3 hours, I check the loads days/weeks in advance. I prebook a jumpseat if really urgent, but I NEVER expect it.
I'm polite to check in staff, never pull rank, always dressed in a suit.
I don't ding, barely leave my seat, I even take my own litre of water and snacks so that I don't have to bother crew. I take what meal I'm given and am grateful if there even is a meal for me. I sit quietly, I'm anonymus. That's the way a ID90 passenger should be and even if you ARE paying full fare ony ANY airline including your own, you should always behave like this.
