After being burned by a TA, several times many years ago....I finally took over all bookings for our travel plans, which I enjoy. She got lazy, with the booking the easy stuff of the international travel plans he needed for his career. When I tried to use her for our personal travel, she was awful and also unresponsive. (Must have been too complicated for her).
So I then started booking all his business travel myself, with really good results. Enjoyed it so much, I started doing all our personal travel. It is so much fun to do so, and I am in control, which is important to me.
