I live in Philly so I should like US Airways, but United is so much better. There is hubs are in the bigger cities (Los Angeles, San Francisco, Chicago), not like US Airways and American which have hubs in places like Dallas and Charlotte which aren't the biggest of the biggest cities. I also like the Denver hub, because you have an easier trip to the Mountain time zone,not having to stop in Chicago.

Dallas has 1.2 million people and San Francisco has .8 Dallas is the 4th busiest airport in the US and the 7th busiest in the world. So, I don't really understand your statement. I fly based on available times and price. I always fly Southwest when available. They are far easier to deal with and they don't have charges that add up=free baggage and free changes.

I meant more people would rather go on vacation in San Francisco than Dallas

And the only reason Dallas is one of the busiest airports is because its a major hub for American, United is good for families that are going on vacations, beacuse their hubs are in Los Angeles and San Francisco, and even Washington D.C. that are population destanations for family vacations

And I guess the only airlines that fly to D.C., L.A. and San Fran are United, right? No one else flies there?
Funny that on another thread, you're touting US Air to Hawaii. By your own logic, shouldn't you be on United connecting through L.A. or San Fran since they're such great cities for family vacations? I mean, with a two-hour layover, you could make a quick run to Disney and back.

I'm sorry, but this thread is just ridiculous.
