I am flying on American this weekend and it is rather disappointing to learn that all English speaking movies/tv shows available for rental do not have English Subtitles or Closed Captioning. This is not only beneficial for Deaf customers or those who are hard of hearing [as of 2013 there are over 48 million people in the USA that are Deaf/HoH], but I think the vast majority of your customers would appreciate having the option. Not everyone has nice headphones or brought a set with them and sometimes it can be difficult to listen to the movie in such noisy atmosphere. I know a representative from Gogo monitors this thread and hopefully this is something they can implement. Be a leader!
