Just got off Fin 742 (C-FIVS) 777-300ER operating AC1175.
Realized I lucked out today when stepping onboard. Love the new configuration, IFE is the updated 787-9 system with 3D views and HUD display. Very cool.
The self-serve bar has sadly been replaced with closets. Not sure what will they be used for. Space in the door 2 galley seems otherwise unchanged.
Overall a positive change, at least for the J/PY cabins.
