Very rough getting into denver. my kid threw up it was so rough.

Why wasn't this flight departure scheduled eith another crew so that it could leave on time? When we arrived in Denver we had so little time between flights we had run to the connecting flight. We should received some credit for the inconvenience.

Efficient, calm when things were delayed and kept us regularly informed of what was happening.

I was supposed to be on business class at first class from Denver back to Miami due to weather changes. I missed my connection and it’s put on a flight to Fort Lauderdale. Instead of honoring my business class/1st class ticket, they put me in coach, but there were two first class seats open. I think it’s absolutely disgusting that I paid for first class $1300 ticket and they put me in economy and they had to open seats available and I have still not been refunded the difference. I ended up having to eat a snack box instead of the meal I was supposed to get and did not get home till 2 AM so I think that’s a little pathetic that I had to live off crackers for dinner And my poor dog ate some cheese and salami. Oh yes, apparently when they switched me to the new flight they forgot to mention I had a service dog

Excellent service despite turbulence during the flight. Flight attendants were remarkable!

Flight attendant moved my bag without notifying me and was rude to me when I asked him about it. There was no reason to move it.

Plane temperature was comfortable (not to hot) when boarding and waiting for takeoff.

Food choices were very limited. Taste of the dishes was average.

I liked all the informational texts. I always knew where to go and when .

Not as good as expected Air Can needs to improve totally rated on internet as worst

Took off on-time and staff was very nice. Got stuck on tarmac at ATL due to storms, but staff was still wonderful even though they were working and not getting paid.

In a nutshell, my bag, the one I have to pay for, because now you can’t even bring a carry on, did not make it. I am still waiting for an update. The fact that not only were have to pay for it, but on top of that we are stuck without getting it, it’s ridiculous..

The plane was filthy!!!! There were empty food wrappers in the pockets and worst of all a wad of hair where someone had obviously brushed their hair, cleaned out the brush and left the wad of hair in the pocket. It was the most disgusting thing I’ve ever seen!! The seats are so crammed together with NO leg room. The AC vent controllers do not adjust. I will likely not book another AC flight from Florida to Montreal.

This was an excellent experience for a very short flight.

Registered my luggage at 5pm. Arrived at JFK at 1:00 am. Worst trip ever. Never again

Really good, super comfy flight and the stewardess was great.

Air Canada never runs on time. You’re lucky if your flight is not cancelled or diverted. Worst airline in the world for gas lighting its customers.

No space in overhead bin, one cookie, 2 oz of juice - is not customer service.

Good flight, friendly crew and overall - good service on United Airlines.

Received email saying that there won’t be a seat back entertainment screen and inflight WiFi would be available. But no WiFi both ways. Say it in the email.
