How closely related does the caller need to be to the passenger. I probably handle all the airline stuff for 20 different family members and friends. I have all their passwords and information and they just trust me to do what's best.
I normally pretend to be the passenger or their husband. Do I need to pretned or can I just be honest about who I am.
For instance if my uncle ask me to use his wife's miles for an award ticket for his daughter. I normally will claim to be my uncle and say that I would like to use my wife's miles for my daughter. Can I just be honest and say that I'm booking a ticket for my cousin with my aunt's miles.
I recently had to book an award to Bali for my brother's wife's sister's fiancee. It probably would have seemed rather odd if I admitted who I actually was.
