If I were in your shoes I would check out the tramp freighter schedules. That would get you back to the states in about 6 weeks (Just Kidding !!!).
On a serious note, I would only fly on a non-US carrier, as I believe US carriers remain targets, also, stay off of B747-200 series aircraft as it seems the center fuel tank is in question, in my opinion.
Market forces may force your hand as in a couple of months only non-US carriers may remain standing as United and US Airways and others go into bankruptcy.
The market capitalisation (stock price X number of shares of outstandind stock) of CHC or Offshore Logistics is higher than United or US Airways !!!
Best of Luck, and Praying doesn't hurt either.
