In addition, due to cramming so many seats into the Econ, there's less lavatories (long line-ups), no duty free onboard (no room), not enough room for carryon, and very poor service with long waits for food. Carryon bins were full half way through the boarding and it was chaos trying to fit your stuff. Forget about bringing 2 bags or jacket with you expecting it to fit overhead, meaning you need to keep those in your tiny seat further making it less comfortable.

Also, the exit row seats will not have a PTV entertainment screen on the back of the seat in front (as most seats), but will have the video screen stored in the armrest – similar for the meal tray table which will be stored in your armrest. Because of this design layout, you might find that the actual seat width is less than ordinary seats, and it can be quite cumbersome using the PTV and tray tables – guess it is a case of measuring that against the benefit of extended leg space you will get.

As for Vij’s comparison to WestJet: their Plus seating is more pitch, a blocked middle seat with a free sandwich and snack (and unlimited complimentary booze). AC’s long haul J service includes 4 hot meal choices in china dishes, and two premium red, 2 premium whites as well as expanded beverages (Cranberry juice and Perrier). WestJet continues to charge for meals in Y on their overseas flights, AC still provides complimentary hot meals with choice of entrée and free booze in Y on Asia and Europe flights (not US, Mexico or Caribbean).
Seats are a personal choice. Over the wing you will see less. Behind the wing you will have more noise from the engines. Towards the end you will have less fresh air. Close to the lavatories and galleys you will have more people and noise. At the window you are locked in. At the aile you get more disturbed. At the bulkhead you have more babies. They may run out of food options towards the end of the cabin and so on. The perfect seat for one person is a bad seat for another person. Have a look here and decide for yourself:…

@Lucky: “While I imagine these planes will still be primarily used for shorter flights, the decision to fly them transatlantic is interesting.” AC uses these for everything and anything since they freely swap between their widebodies and narrowbodies on flights in North America. So, in other words, we’ll be riding this from Halifax to Vancouver (5.5 hours), Montreal to SFO (5 hours), etc. etc. Lots of looooong flights, so I don’t see why they similarly lengthy European flight is any different.
I flew JFK-KEF last year on DL. It was announced that by the day of my trip it was supposed to be on a flat-bed configuration. Instead it was a recliner, no pre-take-off sparkling as they provisioned for a domestic flight and gave away ear-buds instead of noise cancelling headphones for the same reason. Complained to DL and got 50k points re-deposited for a 125k redemption. I believe that on the longer MSP:KEF route it’s consistently flat-beds.
We flew LHR-YVR on this aircraft and were fortunate to have a whole row of 4 seats between the two of us, allowing us to spread out. If the row had been full, my companion in 61F would have been very squashed as the seats are quite narrow. The in-flight service was much better than I expected it to be - full meal departing LHR, mid-flight snack and ice-cream, then hot snack before arrival in YVR.
Most airlines now charge an additional fee to sit in the exit rows, others will allocate at check-in (remarkably some airlines still favour these seats for much taller passengers!). You do get a lot more legroom in an exit seat, but on the downside there are a few points to remember. You will not be allowed to keep any items of hand-luggage (even books etc sometimes) by your seat/footwell area during landing and take-off periods, and as the bins above your seat may be full by the time you realise, you will have to hope for a cooperative cabin crew that will take these items off you at these periods and return them after take-off and landing!
These planes are configured in two classes of service, with very nice lie-flat sleeper suites in Executive First Class. Pioneered by Virgin Atlantic, the seats are arranged in a herringbone fashion, angled at about 45 degrees to the direction of flight, and might take a little getting used to. Due to the angle of the seats, those that want a view out the window will really have to turn their head. However, every seat is an aisle seat and there is no need to climb over your neighbor or wake them in the middle of the flight.  

I will be flying on this plane from Montreal to London in July. There will be three of us in row 28 ABC - my son will have the window, I will be in the middle and my husband will have the aisle. There are two sections after premium economy, ours is the first one. I see on the SeatGuru website that the seats behind us have alerts - they back onto the exit door area and have limited recline ability. Hence, will this mean I will have limited recline ability unless I want to be a jerk and lean back into someone's face while I sleep through a night flight?
Flew Vancouver to Sydney (return) in business. Air Canada's new business class seats are awful. Lie flat seats are not even and not flat. I am 5'10" and I just fit; if you are taller, you cannot stretch out. But, most frustrating.... the fixed non-movable table means you cannot turn over or bend your legs to get more comfortable. They must get rid of that table for me to ever fly them again in an overnight flight. That said, food great, service great, entertainment OK. But back to the drawing board on bed/table, please.
Air Canada’s configuration is identical to United’s 737-800s up until the exit row — United also has 16 first class seats, and then nine rows of extra legroom economy seating, including the two exit rows (that’s a lot of preferred seats). However, Air Canada manages to squeeze in an extra three seats in the back behind the exit row, though that seems to be accomplished by putting the bathrooms at the very back, rather than in front of the rear exits. In other words, the galley space will be smaller and cabin will be bigger.
✅ Verified Review | A330 seats are extremely uncomfortable. Airlines need to have a 'use-by' date on seat bottoms as older aircraft have seat bottoms which show a high degree of wear. It would seem a low cost to at least build in better cushioning in seats where the flights are 10 hours or more. Feels like some form of torture to make passengers sit in seats like this. A/V system is also very dated and laggy. Reinvest some of your profits in improved seats and a/V systems. Aisles ridiculously narrow. 

We were due to sit in 5H&K but on boarding were switched to 1H&K. I had read many poor reviews about this version of the 777. To be honest, it wasn't nearly as bad as led to believe. I'm 5'10" and 180lb so can't speak for others. Seats were firm but comfortable and it was easy to adjust them to find a comfortable position. The cubby hole for feet was decent enough. IFE was quick and responsive. Tray tables quirky and took a bit of working out . Meals and service were very good. Friendly flight attendants. I understand that this seating will be replaced with that used on Air Canada's 787's.
