No upgrades for me alas so on my last US trip had to travel in economy on the AirNZ 777-300 (I guess) from AKL/LAX return.
On both sectors I found the in-flight system very unresponsive to touch and I had to press several times to register actions. I often ended up using the remote as it became quite frustrating. Have others noticed this or did I just get unlucky and get a bad seat going both ways?
I think they are Panasonic based systems from I heard once but I can't confirm that.
