Hello there,
I can't comment if AM was giving locals a hard time on the sim. Maybe yes, maybe no.
On the other hand there are some local captains that will make you sweat on the sim if you're an expat.
There was one A320 examiner failing expats
systematically on the sim. His preference was so obvious that he was called in the office and warned to change his attitude some years ago.
Every outfit seems to have this clash of groups. Go to Emirates, Cathay and you will find aussies x brits x americans x locals. In companies experiencing merges, you will clearly see an undeclared war of parties.
In my personal experience with GFA, I couldn't really say until now that my examiner was giving me a hard time because of my race, or my religion.
Nevertheless, I can assure you that as an expat pilot with GFA, I fell only
tolerated in the cockpit.
