Air Canada

Heathrow to Vancouver and seats were comfortable enough and legroom good. Seat recline was ok could have been better though.

GVA-YUL-YYZ. Lucky that plane was half full I could move to a center block / aisle seat after a while with better access.

Not sure how anyone can state that Air Canada seats with good recline. It hardly recline at all and when the seat in front of you recline you have to recline if you want to watch the video better otherwise it is really difficult.

Seats 26G and 28H on my earlier flights. While tight and getting uncomfortable towards the end of the 14hr flight they weren't bad. Seat recline isn't too bad if you are doing it yourself but for someone behind you it can get close to claustrophobic. I have since had seats 18B and 18G with nothing in front of me but a wall to Executive first. The seats are narrower and don't have moveable arm rest thanks to the try being in them. Check in online early to get the best seats you can is my advice.

YYZ-STL-YYZ - Seat 13A is the worst possible seat you can get. You feel cramped no recline ice cold aircon is blowing on your head and you have a direct look into the lavatory. Barely survived the 2 hour flights from Toronto to St. Louis and back (no other seats available as the planes were packed)

Boeing 777 Seat 33H flight back A330 Seat 24G. Seat quite comfortable and enough legroom personal entertainment system with ok selection food average service not very personal but efficient. Be aware A330 seat pitch in economy is varying from 31' to 33' in some planes depending on where you sit - and you also might have to live with an entertainment box limiting your legroom.

YYZ-NRT-YVR-YYZ on B777-300 series. Despite the fact that aircraft type were the same the long 13 hour flight YYZ-NRT in seats 52A&B actually seemed more comfortable. The return flights in seats 33A&B seemed less so. This despite the fact that the B777-300 from YVR-YYZ had a better equipped cabin (winged headrests reliable VOD).

Seat 20D from JFK to Vancouver 26D on the way back. Seats are pretty decent and IFE is great. It is a small plane for 6 hour flight and with only two bathrooms for economy there were always long lines.
