Got the same email today!
At first glance it looks like P2F advertisement, but I guess they forgot to state the fact that you have to pay. I later found a price list for line training. Also it is a bit strange that they are inviting people to come all that way for the first interview, usually there is a Skype interview first.
I asked a captain on A320 who was flying in Cambodia recently as a contract pilot, about AAS and hes reply was...THERE IS NO SUCH COMPANY IN CAMBODIA. I think he would know who are his company's competitors.
Anyhow, it sure smells fishy. Either its p2f or scam...or both. I will reply on their email and ask for more info, just to see what will they reply and than we can compare their bull....
