I met my wife on the training course for an airline. At one point we were both Pursers and handed the aircraft over to each other on occasion. Wouldn't see each other for a week or two.
I am still in the industry ( management) and my wife a housewife. I travel quite a lot with my position to various trade shows.
It is tough leaving the family behind and not quite as enjoyable as it used to be but the fact that my wife understands the industry makes it slightly easier on our relationship. Makes the coming home all that more precious!
Cheers
