I work as a doctor.
The hospital I worked at last year had 2 other ex-FAs - one doctor, one nurse.
From my friends (some of whom have been forced into other employment), some are nurses, some are parents, others work in hospitality industry; some even work for rival airlines, as ground staff.
I bump into ex-FAs everywhere, doinf all manner of things - like most everything else in life, you can do it, all you have to do is give it a go!
And yes, it DOES look good on the CV, and is always an excellent conversation starter!
