No one likes being reminded that other people are getting better treatment than they are, especially after they've shelled out a hefty sum for a flight.
What utter nonsense! You pay for what you can afford. If you want a better lifestyle you need a good income. If you want a good income you work hard for it. End of. As for shelling out a hefty sum, what do you think those in Business Class have shelled out then? Finally, as already mentioned, most of the operators who suffer above average disruption don't even have Business or First class. No, the truth is that the pond life of society can now afford to fly and behave on a/c just as they do in the street.
