The No. 1 problem [for United] is the hub and spoke model isn't working in the post dot.com and post 9/11 era. The networks are a good thing, and they're here to stay. But they cost a lot of money to run, and the industry has to do some things to get the networks more efficient. The business model for hub and spoke got out of whack because during the dot.com bubble, they were raising fares because they could and they didn't do the things they needed to do.
