I always speak up if I think service in J or F, or at a 5 star hotel, is under par and I do it in a polite non aggressive manner. Usually it draws an explanation, sometimes an apology, and in the case of Asiana (where they questioned whether we were 'OK' to have a third glass of wine) it drew a completely patronising lecture from the crew leader. But any whiff of over-reaction from any flight crew and I'm as quiet as a mouse. I understand what you're saying!OP, you are lucky, yes, I know, people do have a right to let the company they pay to use the service of, what they expect, but when it comes to an airline, I would be scared of making too much of a scene on the flight.
Things could go pear shaped and you find you have the men and women in blue waiting at the end of the flight.
JQ had pushed me into a bad spot, when they cancelled a flight I really needed, but I didn't kick up any noise when I called their call centre to see what could be done, I didn't kick up a stink either at MEL airport when I found out my flight got cancelled.
I just won't fly with them again.
Don't want the AFP called.
All it takes is for one person to feel a threat, even if you didn't mean it like that, and your whole trip could see you taken away and chatted with.
