I just flown the CX 773ER B-KPA & my seat was 11K, the AVOD wasn't working at all. The flight attendant had to look for other empty J class & re-located me to somewhere else. I remembered when I look around other J seats, some of them (AVOD) just hang (screen forzen) but it seems that those business travelers were busying working on their laptops, they wouldn't care which movies / airshows that going to show...
