Probably been brought up by others already but I just took my first AC Rouge flight to Osaka on their 767... and boy was it uncomfortable. The aircraft is ancient, 1995 build with nary a refresh. I knew and researched what I was getting into but it still under delivered on all regards, especially the amateur hour service by what I felt like were high school students. An hour between meal service and tray collection, and not even knowing what was inside the meal besides "its chicken" are just examples of the poor-training and service standards.
In comparison, I flew the slave-ship, the 777-300ER in HD configuration on the way back from HKG and enjoyed that. Atleast it has real IFE to distract you from the smaller seats.
EDIT: Suffering from jetlag allowed me to compile this quick video review of the AC HD777. Dreading to relive the Rouge flight so going to hold off on that for a bit LOL.
