I use to Jumpseat with them regularly out of Hawaii. I know what you mean, Airplanes were in terrible shape. I remember the lunch they served was in a brown bag, I almost gagged on the mystery meat in the sandwich.
On the other hand, the Crews were outstanding, a great down to earth positive attitude - I really liked them. They treated me very well.
As for a bussiness point of veiw, they are making money hand over fist. But I worry about there future since 80% of their bussiness is military.
