A travel expert is forecasting that AA, United, and US Airways may enter into bankruptcy in a few months - and as part of that you would no longer be able to redeem miles for flights.

This expert says: "To protect yourself, the first thing you should do is use your frequent flier miles as soon as you can. If they go bankrupt and they liquidate the carrier, the miles will be worthless.”
Does anyone have more information on this likelihood?
