How much time in the 737 do you have ?
Semperfido is on the right track. China can be a bit dicey ( in terms of upgrade potential ). Outside of Southwest, Continental, Fedex, UPS, jetBlue, World, Atlas, Kalitta, etc., I would look at some of the 737 charter operators. Preferably one with some growth plans so that you can get a command. If you are out for some adventure then Emirates, Gulf Air, Cathay Pacific, Japan, mainland China, Indonesia, Malaysia, and Thailand would be worth looking at.
It took me one year to find a job in 91/92 after being furloughed. This time around I had resumes going out within two weeks of 9-11 and only spent 2 months on furlough.
