Very Interesting reading this post.
My previous company was full of married couples, courting couples, and people playing around.
Divorce from one Cabin Crew member, the following week shacked up with another.
Regardless of where people were employed, ie, engineering, operations, crewing, flight crew, cabin crew, or office staff.
My Airline was great fun! Always guessing who was with who, or who we thought they wanted to be with!
My current partner is another successful story from that company, and we are now both employed in the same office in the Middle East.
So my advice, take it easy, but just avoid having to talk work with your partner. Other cabin crew will throw a lot of s**t if they think you are getting favours!
