While I agree some responsibilty needs to be taken for mainlines pure focus on the bottom line, I do think this is quite the slippery slope. While it may riegn in the so called 'bottom feeders', it just sounds like a new avenue for lawyers (not that they haven't taken it as mentioned earlier). Let's remember that Comair (5191) is about as far from a bottom feeder out there. While some responsibilty should fall on how mainline chooses their contractors, I think it should be evaluated on a case by case basis. Fankly, I think our legal system already polices this. Regardless if they are going to be held responsible or not, the cost risk benefit may still fall in mainline's favor to choose the lowest bidder.
