Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

My bag was lost with my medicine and I am very inconvenienced. I don’t know what happened, however I want you to do a better job on getting people’s bag back

Do not like the feeling of being in the basic economy. Everyone should feel good no matter what.

So so. Terrible aircraft choice for that leg of the flight.

Our seat tv didn’t work All the rest was perfect

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

Meals were adequate but could be better. Lots of movies, podcasts, tv shows. We really enjoyed using our personal headsets highly recommended. 15 hrs flight great to travel at night.

This was a Lufthansa flight. Disappointing main meal. Very rough over Canada and arrival at FRA. IFE was almost unusable.

the plane was old. the wifi didn’t work. the entertainment was boring and dated. the charging ports were impossible to find. i was mostly ignored by flight attendants that had no problem speaking to the man beside me. i got two drinks the entire time i was on the plane.

Quit making seats narrower and narrower. The guy beside me spilled over in to my seat.

The experience was generally above average. The only downside was the absence of WiFi during my flight from Vancouver to San Francisco.

Headphones for the movies have too much bass and can't be adjusted. Almost impossible to hear. Great movie selections but can't really watch them because you can't hear them. Also the system is very slow.

Once again my complaint is how close the seats are together. Also, the bathrooms were not very clean by the second half of the flight.

Excellent in flight service, perhaps the best we've ever had. Business class feels tired and needs improvement to compete with other airlines. The food looked good but tasted terrible. Check in was quick, the flight arrived early and our luggage was on our flight with us.

Terrible quality wifi and they charge a lot for it. They nickel and dime you for everything.

It took 5 hour to get a crew to D Ice the plan. We had to sit on the runway for 5 hrs. in Calgary. It snows most of the winter. No proactive plan. In addition, after 3 calls to customer service they couldn't figure out how to have my wife and myself sit together on her birthday weekend. Everybody kept passing the buck. No decision from customer service, luggage drop off or check in team. The experience was a complete mess! I don't think we'll ever fly on this airline again.

Of our SIX flights in my travel group, five were delayed, and all (except possibly one) were just company screwups. One traveler had her CARRY ON baggage put on another flight because Air Canada could not properly do "weight and Balance". Bags missing for a day. Another traveler never made it. Then, (humor here) the flagship airline of the socialist country has NOTHING FOR FREE on board. Expect to pay for pretzels, folks. How's that socialism working out for ya, aye? I might book air Canada in the future if I have a meeting that I REALLY want to MISS!

I don’t know if there were any snacks served on the 5 hour flight. I might have been napping when the attendants came around. But I usually wake up when they do.

I supposed to have a wheel chair waiting to take me to the luggage carousel. Didn’t happen so I had to walk up the walkway with my cane. I lost my balance and broke my little toe on my right foot, which means that I’m hobbling around with a very painful left leg and a very painful toe on my right foot. It was a nightmare.

Food offerings need to be more plentiful and beverages need to be more healthy.
