Ageism is a growing problem in the work force generally.
Display these tendancies in a job interview and for reason of political correctness you’ll get a “don't call us we'll call you" notice.
Chewy , in your interviews with BA you told your prospective employer you loved meeting people
You did not reveal yourself as an ageist by saying you only wanted to work with exciting and beautiful 20 somethings.
You have not kept your end of the bargain.
You are an imposter and a fraud and you have only two options .
Tackle your prejudices head on . Maybe check out your local club or Pub for an upcoming "grab a Granny ,or Grab a Grandpa , (depending on your inclination) Seniors Night".
Only joking.
I also hate to tell you this but running off to charter won’t solve your problems.
Which leads me to your second option which is to go back to the sound and lighting industry before gerontophobia sets in.
Get out of aviation Peter Pan.
Not joking this time.
