AVOD did not work in Business First throughout the flight--worked in Economy. The Purser or Service Director said she was not going to report it for us to get compensation and that I should go to either the UA-or CO website (she was not sure). She too tried to work on it inflight but it was not reported on the ground. No Skykits or anything similar were available. If I write to 1K Voice do you think they would respond? Happy Holidays
