Yepper!
I usually let the attendents know that I am deaf and I will need to know when they start boarding. Sometime they lets me and people with physical challenges in first. Sometime I just go with the people that get in the plane at same time. About everytime I get on the plane, I inform the flight attendents that I am deaf and they might need to write it down if they wants to talk to me. After that, no problem!
One time, I forgot to inform the flight attendent that I am deaf... I was asleep while flying to Portland, Oregon from Minneapolis, Minnesota... The flight attendent tried to get my attention by yelled at me non-stoppable... The person who sat next to me and shook me to wake me up. I woke up and looked at the flight attendant. She gave me an attitude by said that she doesn't apperciate that I ignored her when she tried to talk to me... I informed her that I am deaf and I am sorry I forgot to inform you... She rolled her eyes and asked me DO YOU WANT A FRICKING DRINK!?!?!? I was like oh wow... Water please... She gave me the drink and moved on with an attitude. When I landed at Portland, Oregon, I was getting off the plane and that woman gave me the mean look and I told her to get over herself and grow up! She gasped and yelled at me GET OUT OF THE PLANE! I filed a complaint against her for violated the code of ethics. The airline apolopized to me of what happened but they didn't say what happened to that flight attendant.
