Hi, I'm flying from Manchester to Newark in September with United airlines on flight UA21. A little bit of research has shown this is a 757-200. I was just wondering if anyone who has been on this flight knows if they have the seat back TV's? I've checked the website and it says two different things in different sections. On the plane layout it says overhead tv's but on the in flight entertainment section it says AVOD. Can anyone confirm if it is the seat back TV's please? Thank you!
