I'm going to add to everyone who likes Southwest. I tend to do a lot of flying, so here and there, bad things happen - flights get delayed, employees get distracted - but they have a consistently strong standard for customer service. The food is pretty non-existent, but the employees actually seem to want to be there (and internally, Southwest is well-known for succeeding well with its keep-our-employees-motivated-and-happy training). They actually make people laugh while they're flying, which nobody else does.
