I don´t know if there are any plans for 747, yet. With the 747-400 being replaced by the A380 and 747-8I soon I don´t know if LH has still plans for them except converting some of them into freighters.
How about the A300s used for longhaul flights will they get PTVs as well ?
It will forever be a McDonnell Douglas MD 80 , Boeing MD 80 sounds so wrong
