So, US Airways didn't take any financial hit, lawsuits?
Air Midwest would have bore the brunt of the lawsuits, not US Airways, but in any event, everyone has insurance for things like this. Perhaps Air Midwest's insurance premiums went up a little bit. US probably suffered minimal booking away, since the media coverage generally referred to the "Air Midwest crash" and not the "US Airways crash". Of course, it's not a good idea to make a habit of these things.
I'm the expert on here on two things, neither of which I care about much anymore.
