I just got home from my flight from POS with Z4 on C-GZUM City of Ottawa and they have just finished refurbishing this aircraft with new washrooms and fully leather seats. It looks very classy and nice. On my way down to POS from YYZ on the 1st of NOV, the seats were falling apart and the material was ripping off. I was thinking, they needed to do some refurbishing. To my surprise boarding the return flight, the entire economy class is leather now, and the seats are comfy. They have the same color as air transat's leather seats in economy. They have a really good service as well.
