No
Just think how disrespectful that is to the hundreds of professional flight attendants out there that are trying to earn a living. Obviously this would not be this case if your wife already is a professional F/A, or really wants to be a professional F/A, not just go along on the “cool” trips with her husband.
Also, it’s hard enough to get the people in back to believe that corporate F/A’s actually enhance the safety of flight, just imagine if the people in back thought that the F/A job is just an excuse to bring the pilot’s wife along.
Save everybody a lot of headaches and simply airline your wife to the cool destinations.
