The answer is to stick with one's favoured airlines:
Between Europe and my current location, for their food and schedules, I'll happily use Cathay Pacific all the time if their fare is right.
I'll happily use Swiss out of UK (LON, BHX, MAN) because often their fares are cheaper than the supposed LoCo's, they offer schedules to suit and their cabin service is second to none.
The few times I've flown with SAS, despite paying for their drinks and grub, it was of a good standard and one could eat and drink as much as one liked.
And even Ukraine International Airlines, reasonable grub but the (Ukrainian) Slavutich beer came in 500ml cans (none of your nancy boy 250ml mixer sizes) and so complimented would the Ukrainian cabin crew be that one actually liked their beer they weren't stingy with it either
MALEV was another good one but alas they've gone.
Stick with the ones that offer a quality and bin the ones that don't.
