Why are guys nowadays afraid to marry flight attendants as their wives?

A male flight attendant from an airline company complained that out of their crew of 20 flight attendants, actually 18 are still single. They are almost crying from worry in private.
Every time they go on blind dates, they talk about fashion and travel, everything goes well. But as soon as a guy asks what they do for work,
and they say they are flight attendants, the guy quickly ends the conversation, as if encountering a career taboo and avoiding it at all costs.
This also makes him very puzzled. Flight attendants are supposed to be beautiful, dressed in professional attire, and very elegant.
Plus, the company has formal employment, with all social insurances and housing funds in place. The job sounds glamorous and respectable,
so why does it become an outcast in the marriage and dating market?
Even more strangely, several married flight attendants have now returned to being single.
I want to ask all the brothers here, has anyone married a flight attendant as their wife? How is married life really?
