There's no such thing as a "real" airline....... we all fly in aircraft (whether it's a 747 or an A320 they all fly at the same height and fly as fast) and we serve passengers......
The way I see it is we need to help each other out. I've had "special" treatment from other airlines because of my job and I'd help out staff from other airlines on my flights.
It's like coach drivers, they all wave to each other. I've never seen National Express look down their nose at Wallace Arnold!
