With respect to attorney's fees, I'm a little biased being a lawyer, but let me tell you, the only firms capable of handling bankruptcies of this magnitude are large nationwide and multinational firms -- and they charge a lot. Their bills have to be approved by the bankruptcy court, but they will still be huge.
Think about what the bankruptcy lawyers have to do: prepare and file the original filing, maintain contacts with ALL
creditors and ensure that the appropriate people get the appropriate priority, ensure that no creditor is harassing United, etc. etc. etc. It's a big job.
I'm not saying their bills are 100% justified. In the Enron case, a firm had its bill whacked by a third -- from something like $60 million to $40 million (the firm lost $20 million in the blink of an eye). But it's not unheard of for these things to get expensive. Sure, some people are getting rich here, but what are the lawyers supposed to do -- work for free?
