Expectation
I don't think it matters whether you fly F,J,C,W or Y: what matters is the expectation of service the airline, it is irrelevant what they call themselves, generates by their advertising ( mere puff excluded) and more particularly these days their website.
If West London Airways promise you " an experience" in C or F you have every right to expect them to deliver: if South London Airways adds some value to their product e.g. limo service you may elect to use your hard earned cash to pay for their product over the former.
If you pay £2 for North London Airways loco flight and add £X for speedy boarding you have the expectation that you will get what you pay for.
The problem all airlines have is delivering that promise or expectation because so much of the ground side is contracted out.
The ground handling side is, like the aircraft you fly on, provided by the lowest bidder.
