The advantage of bankruptcy is the ability to restructure debt and the company easier. I would look at what American Airlines current bankruptcy as a good model, they are making massive structural changes to the company and making some good strategic moves (repalcing the older MD-80s with newer 737s for domestic routes, that is a 300+ plane order for Boeing, that will let them increase passenger loads be 40-ish per plane while spending less on fuel), reworking out-moded labor contracts, etc. American will be in the tank for a year+ stock wise, but will most likely come out of this with a better overall business that can cope with the "new world"
I think the car company bailouts let them weather this storm, but I did not see the longer term fixes that may be needed.
In any case, I think the video was not really accurate, the car companies would not have folded if they went into bankruptcy.
