TBH I hate to say it but broxi is correct (just due to his name
). Go for Cabin Crew and not a GHA.
At least once you work for an Airline (NOT AN LCC) you will get ID90's and information on internal employment opprortunities as well as Airline Training on their specific product....
IMHO keep away from PSA work for a GHA. Either Cabin Crew or at least Dispatcher (Flight Coordinator) position for a GHA.
Again GL
