Pretty basic service.

The late morning flight we booked was eliminated from the schedule, requiring us to book an early morning flight. This resulted in our having to spend our last night in a hotel near the airport rather than in Rome. It also resulted in a 4+ hour layover at Heathrow, rather than the 2 hours we anticipated. Very disappointing.

Not enough overhead bin storage space. If they want to start charging people for bags they need to improve their overhead storage ability. This was a commuter flight from Amsterdam to London. So the entertainment was not really there

There was a good selection of very different movies to watch. I found four that I wanted to see.

There were not enough chairs in the waiting area. There was a long wait, first, just to get on the plane, then, instead of letting us stay in the waiting area, we were all seated, and left waiting for at least an hour, most of that time without explanation, sitting in a stifling plane at the gate, without being allowed to get up and move around. Also, the ratio of carbohydrates to protein in the main meal was way out of kilter. I don't want rice + potatoes + bread + crackers all in one meal, with zero vegetables. The tiny piece of cheese helped.

The crew is excellent. Very friendly, professional, and helpful. Both on board and at the desk inside the airport. They listen to your needs and respond the best they can. Seats are comfortable enough for Economy. Good selection of movies to watch. The flight was on time and arrived even a little earlier than expected.

The food was filling, but not particularly tasty. For those seated toward the back, there was no choice. Although maybe there was no choice to begin with. Normally, on international flights, for the first (bigger) meal at least, you are given two choices, such as meat or vegetarian, beef or chicken. The food itself wasn't great. The salad was below average on both flight, from and to Chicago. So was the desert. Drinks are offered once with each meal in very small glasses. Although there is a bottle of water from the start.

The flight was not crowded and that was a nice surprise for a transatlantic flight. Each passenger was offered a personal bottle of water upon boarding, cabin crew was very nice and professional. The flight was on time and we arrived at the airport of destination even ahead of time!

There was no soap in the toilet...

Being next to toilets at bulkhead. People queing for bathroom in the extra leg space. I was on the outside seat and people constantly brushed past me and often grabbed hold of the moveable TV set in the dark to steady themselves knocking it. I paid extra money and had more problems. Listened to constant bathroom flushing and odors. Not ideal!

New 787 dreamliner, live up to the hype.

Its hard to sleep as the seat is very bench like. Air Canada's food isnt as generous as it use to be, but their fares are quite low so i guess its a tradeoff.

I bought my ticket with Air Canadafrom Vancouver to Calgary then connected with Lufthansa from Calgary to London UK. Unknown to me I could not find the flight because it had been changed to an AC reference flight. With a very short time for the connection I did not know where to get my boarding pass as my flight with Lufthansa was nowhere referred to ! Not which gate to go . Why not put it in the ticket that Lufthansa and Air Canada work together and that both flights ref should show !! It would avoid a great deal of anxiety . Only offered 1 round if hot drinks over 9 hours ! Departure delayed by nearly 60 minutes
