I flew from LHR-ATL a few days back in First. First off, the flight was fantastic and by far one of the best crews I've had on a BA flight (review will come soon). However, I was quite disappointed to see that the audio jack for the IFE wasn't functioning properly. There was significant static and the audio would cut in and out. I initially thought it was just the headphones that wasn't working properly, but the problem continued when the FA brought an additional pair (one from F and another from CW). Unfortunately, the first cabin was completely full and couldn't move me to a different seat. So, for the entire 9 hour flight I really couldn't use the system. It would take me near an hour to watch a 22 minute tv episode because of audio issues. It's an aging cabin and do understand that issues like this could occur but I feel that this is unacceptable, especially in First. I already went ahead and submitted a complaint but I'm curious to hear about your experiences with similar issues and what kind of compensation you received.
