> Currently air travel is a completely homogeneous service. There is basically no difference from one company to the other Southwest has a pretty loyal following since you can "refund" a ticket for Southwest credit good for a year. Alaska and Delta don't charge for bike fees (they're just priced like ordinary luggage). And aside from maybe 1K members, I don't know anyone who enjoys flying United.
