Scam
It’s a scam. I believe Airlink lawyers are trying to get the scammer shut down.
Airlink is a real airline, with a training programme in house for their Embraer and Jetstream fleet. The scammer is using their name, and also other low cost carriers (the 737 operators).
There is no pay to fly scheme in SA and all the operators train their own crew. Some of the pictures are of real crew, but the names,location and their testimony are fake.
