Roughly 3 months and I started in April 1989.
450 hours total, I had 5 interviews, 3 job offers and 'chose' my first airline - Air Europe.
Great first two years and then the airline went bust. Out of work for a year and (B757rated !!!) no one would touch me with the proverbial barge pole.
I never did find such a good airline as AE and wish I had left the industry then and done something sensible.
