The experience was good just the upcharge of over a hundred dollars was not cool.

No internet, not even westjet connect makes for a boring flight

Our first flight from LAX to Winnipeg was changed but you never informed us at all. It went from a nonstop flight to a stay at Calgary. This impacted our trip negatively as we arrived much later than we planned to. Our returning flight was horrible. The flight was delayed 6 hours!! And we were NOT going to wait that long. The only way we got on our original flight was running there. However all of our suitcases were now coming on the delayed flight. It was the worst experience we ever had flying. I want my money back.

I like the web site, prompt notifications, website checks in process, and airport check in. The flight attendants are attentive and polite. The return flight was 2 hours late and reason vine doesn't sound like an unplanned and unexpected issue (scheduled plane maintenance).

Good, a bit cramped in the seat as my neighbour was a bit large

Please make more option. And be more precise on the type of food you giving. Diner and breakfast can be different

The keg from Edmonton to Toronto My wife found it very cold. Other than that great flight.

It was generally pretty good, but the check-in and boarding process were a little difficult. Check in was in terminal 2F, but there was a shuttle required to get to the gate, which added significant time. The gate was changed 30 minutes before boarding, which took us by surprise - we did not get the notice until boarding had started. The check in line moved very slowly - the agent was friendly, but did not seem very efficient/urgent given the growing line.

Delays and missed connections were very hard the crew were wonderful but 1 1/2 hours late from Abbotsford to a 4 hour wait in Calgary was too much. I am 79 years old and I didn’t get to my destination until after 1 in the morning. They could have offered a seat in the lounge or a meal. I was very disappointed in the treatment

No dogs! Can we have no dogs in the cabin? Why was there a yappy little dog behind me? Lucky I had ear plugs. Sorry for others without

Had to cancel flight due to strike. Hope things will be better next August when we will rebook. Very disappointing as it was our 50th wedding anniversary celebration l!

For the price, it was a really good experience. There was no entertainment on board, so I couldn't really rate this, and I didn't order a meal. I appreciated that there was a free glass of wine.

I’ve wasted 7 hours of my time because of the delayed. ;(

The crew were fabulous. The flight was bumpy and I always like the captain to tell me what that is about or my imagination gets carries away.

Overall great. The crews were lovely. The seats are awful. I always emerge with a back ache.

Short flight. Everything was fine except the flight was delayed twice for a total of an hour.

Would like whole can of pop for 2. Treats were not great . The garlic pretzels were terrible for someone who can't eat garlic. Passenger was 84.

I had boarding pass on my phone. Husband and I were seated together. Agent printed out boarding passes and we were separated for the flight

You was on strike and I had to get another r flight and you did not give me my money back

The internet connection was perfect, and the updated entertainment systems that allow me to connect my Bluetooth earbuds was excellent

The crew was very nice. The equipment on the 747 felt old.

As expected. Would have appreciated a 3-day headsup reminder as a reassurance that all is well.

Poor food on flight between Toronto and Stockholm Airport Toronto too crowded

The plane was late (as was my flight out from Birmingham the day before)

Business Class Configuration was excellent- private and comfortable. Crew and service were excellent. I really appreciate Air Canada cabin pressurization equal to an altitude of 8,000ft. Upon landing, I felt more alert and refreshed than typical for international flights

Hard to use tables and TV screens interfere with the enjoyment of flight experience. Other than that it was a smooth and comfortable ride and we were well taken care of.

Excellent flight overall. Lufthansa Business service was excellent with great cabin crew and very good food and wines. The seat comfort was excellent. Only a slight reduction in score due to the 747-400 being a relatively loud aircraft these days.

The flight was delayed by an hour. Made the connection uncomfortably tight.

When we went to the lounge they told us to go into the main lounge and not the full business class section, later they told me that Lufthansa wont pay the full fee to alloq the business class passengers entry to the nicer sectikn where all the other airlines nusiness class passengers go into. Very poor arrangement.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.
