The 433 seat B747-4F6 of PR doesnt have PTV's.
Business class is in the upperdeck. However, service is very good. You cant really compare PR with the likes of TG/MH/SQ/CX/JL, because these carriers have brand new cabins. However, service is just as good or even much better than the mentioned carriers.
Flight has a technical stop in HNL on the way to MNL, and is non-stop coming back.
The only B747-400 that has ptv is the ex Kuwait Airways jet registered N754PR.
