I saw the topic on drinks on flights, so I thought I'd get a somewhat related topic going as well. What airlines do you monkeys prefer (from a passenger's perspective). I used to be a diehard Virgin America fan (live in SF, flew often to India on its partner, Emirates). However since the Alaska merger, I decided to consider other options.

Frankly the top three (United, American, Delta) all have been aggressively stepping up their game with the increase in competition from abroad. United in my opinion has some of the ugliest interiors of the planes, as compared to American which has a slick look or Delta who has mood lighting and modern features on the majority of its planes (United has just started updating its fleet's interiors and American still has the giant surplus of garbage ex-US Airways planes). However, how is the service on these airlines? How often are delays? How good is the route network? How good are the partnerships (Star Alliance vs. Oneworld vs. Skyteam)?

What do you guys think?
