I will hit 1 million flown United miles next year sometime and haven't had the same bad experiences I read on here about. Now Delta and American don't get me started. I used to like Northwest when I lived in MN.
I have flown a number of non US carries, Cathway, Singapore Air, India Air, China Air, Luftansa, SAS, Air France and others I am just not remembering off the top of my head. Singapore was my favorite, but for reasons that didn't have to do with food
