So where do you draw the line as to what is a legitimate complaint versus a 'whinge'? Certainly not just on the basis of where statutory compensation is due, otherwise someone in F asking for compensation for an inoperable seat would just be having a whinge, right?

How about when my family and I were stuck in a packed T5 baggage hall for over 2 hours after a LH flight, because BA consistently fails to get their act together over baggage delivery? Am I a whinger for complaining?

Is the brunch and supper thing just a load of whinging and we should suck it up because BA clearly needs the extra revenue? Note that I am not commenting on the rights and wrongs of BA's AI-bot lobbing random £150 vouchers at people...

I'm sure we all have a personal view on what is fair to complain about or not. But I'm equally sure we will never codify that nor come to a consensus about it on this forum!
