I was thinking about the motivations for dumping the stocks at such a low price. Besides the obvious that he doesn't expect a rebound anytime soon and would prefer the liquidity, but I am convinced that Warren Buffett is thinking that a majority of US Airlines will declare bankruptcy, therefore dumping the stock now is the only choice.
Airlines having hundreds of aircraft ($100+ million dollar assets) sitting on the ground with no future projections of many of them getting in the air soon, means that they many of them will have to declare bankruptcy. This will allow for them to dump a large number of their more expensive leased/financed aircraft that don't fit into the new passenger volumes and will also allow for them to cut other huge assets (remember the AA bankruptcy where they attempted to cut pensions by over 50%?). I think the public will not except the amount of serial government bailouts that would be needed for such a protracted length of time and the only answer are mass bankruptcies.
Of course this will have to be on an airline by airline basis, but I can see UA, AA, DL, G4 and others having to do so. I am not so sure about WN..
Who knows, but I think we will see a long line of US majors declaring bankruptcy over the next year.
