I was fortunate enough to travel JFK-LAX-BNE on OJM a few weeks back in J and it was very very average. Nothing wrong with 744, but the seats & IFE were rubbish.
Code shared on Emirates and LAN on an economy QF ticket to Santiago a year ago. Our three little kids loved the headset games on the IFE - they don't have much video game time at home.
At the end of our holiday, we travelled home economy on a newly refurbed QF747. For the week leading up to the flight, the kids were getting all excited about playing video games for 14 hours non stop on the way home. It's all they talked about the night before we left.
The look on their faces when they saw they saw the IFE and realised that there were no games was heartbreaking. First world problems I know. Very much so, but now when they flick through magazines and see an emirates tail, they talk about the fun trip. Not a peep when they see the roo tail. Advertising and experience starts young. (Shell and Lego anyone?)
