Western people have demonstrated that they want the lowest price possible - and we have it!
Not necessarily ...
When I lived in the UK Midlands I would endeavour to travel thru BHX which normally entailed the likes of KLM, Swiss, Air France, Lufty and/or SAS ... I wasn't going to drive/travel to/from LON or MAN to save ten quid or whatever.
Where I live now (IAO) the current runway length only permits one local operator, a LoCo, but at least I can buy a, albeit overpriced, beer and a sandwich on board.
Should I dare to fly the, more expensive, flag carrier for 2 hours SUG/MNL one is subjected to a disgusting piece of cake (I don't eat cake) and a plastic cup of water ... even prisoners get better catering than that!
Internationally I have my favoured carriers such as Swiss and Cathay, I will always try to travel with those if only for the level of cabin service and it would take one hell of a (financial saving) carrot to persuade me away from either of those or other favoured carriers I may have.
