I just flew what I guess is an older 753 by the looks of the interior. Direct TV stopped working a half hour into the flight. Two reboots didn't work. The FA suggested that customers would have to file a refund request online. Internet did not work. Front lav occupied light stayed on permanently. My 6B seat seemed to have excessive engine or wind noise - it was loud! I always sit in the last row of the J cabin in every aircraft but in this case a seat up front may have been quieter.
