I have done recurrent with panam four times and flight intl twice, they were both good ok. You are going to get your money's worth with either one take your pick. I did one recurrent with Aerostar and it was a night mare and rip off. They used old manuals from panam just ole cutting and pasting etc. I spent more studying with my sim partner testing him up to speed as Aerostar was just a flat line for instruction.
I have no respect for an outfit that steals sensitive info from another company and runs a cheap ass outfit. It lowers the standards in this industry.
I know an initial student would struggle and come out weaker in the end there after what I saw.
