Well, I must say I am well into the darker side of 40 ( a lady never tells

!!)
But I can tell you this much, I have taken over from several 20-somethings who have ran away in tears after interactions from some vile, drunken creep pax .... give me five mins no matter how angry, how drunk any passenger is ... guarentee I will have them eating out of my hands.
Youth and good looks might be great (had them once

) but I can also tell you that the experience of 20+ years in the skies makes me confident in any situation ...form placating obnoxious old p*ss-heads to more serious emergencies (have had my share of both!!).
and can honestly say after all these years, still love the job, and the pax still love me (even if they cant see my g-string )
