They canceled our flight and left us stranded to figure it out

We appreciated the friendly, efficient, and professional flight attendants. A wider selection of hot foods would be nice.

Did not have enough time from Venice seaport at Ravenna to get to Venice airport in order to make the scheduled flights. Need to have at least 3+ hours from ship docking to airport.

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

As usual, United scheduling is completely misleading. A 54-minute layover at O’Hare is too short to make a lot of connections, especially since the flight landed “on time” but had to wait on the taxiway 15 minutes for a gate to open up. Then it takes another 10 minutes to exit the plane before one can run to another concourse to catch a connecting flight.

The seats on the aircraft are like sitting in a rock. During the boarding process they recognize Active Duty Military, why don’t they recognize Retired Military. I’ve always preferred Delta, this flight confirmed why I still prefer Delta.

The plane used to go to Chicago was a bit outdated and needed a refresh

My connecting gate in .Chicago was across the aisle from my arriving gate. Otherwise I would not have made my connection. So that was very fortunate.

when you can say you don't remember being at any point upset during a flight, the airline is winning .

It was nice being on a flight that had working wifi. The boarding was quick - why don’t all airlines have small boarding groups window to aisle? Makes so much sense!!! I was disappointed to be the first person stopped to have to gate check my carryon. Especially when there was plenty of overhead space at the back! But I get it…keeps it moving. Crew was nice.

The flight from Buffalo to Chicago was on an older and smaller plane. Seating was tight. Looking closely at the interior of the aircraft there were definitely signs of aging and wear.

The flight encountered a delay exceeding 4 hours. The food voucher issued was valued at $12, insufficient to cover our meal expenses. Consequently, I was unable to take my medication, leading to a drop in blood sugar levels and exacerbating my anxiety.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

3hour delay In the last 3 months i had 3 flights and 2 of these had a more than 2:40 hrs delayed

My initial flight to ORD was extended without reason. We circled the airport a few time and then drove on the ground for at least 20 minutes. These kinds of delays are annoying but somewhat expected… it would be nice if the crew would make an announcement to give updates on how long we could expect to be delayed.

Fantastic. I am low vision and was impressed with how helpful and accommodating the service tam was. It was super appreciated! I was pleasantly surprised about how delicious the food was. Like, “I wish I had more even though I’m no longer hungry” delicious. 100% enjoyable trip.

The flight was uneventful. What was a problem was I was delayed getting home one entire day because the flight from Sacramento was delayed. That made getting to my connecting flight impossible. I had to stay another night at the hotel and incur that expense as a result.

Flights were on time both ways, such a big plus! Staff was very accommodating and friendly. Question the choice of snacks that, which on both flights was dairy based. Appreciated using bottled water.

This flight was fine but had no time to breathe as the connection was late from Sea to ORD.. Super stressful. If we checked bags, the trip would have been very distressed.

The flight was delayed for 4 hours and the airplane was really old cuz not one thing was working.

They charge 5 dollars for plastic headphones for a flight of 1 hour! Seats are awful. Service is terrible.

Nice crew - very small plane and uncomfortable, with no entertainment options…

was wondreful! just let me know what airline im flying in advance!

On this flight, we didn't even get water offered, nor any other beverage. Therefore we got a snack of pretzels. Flight was good and Air Canada a good airline

I would realllllly like to have been in a seat closer than row FORTY. Needing assistance - longgg way to walk down and back; then they put me in the middle seat-needing to get up for the window seat passenger to go to the washroom etc.

Everything was seamless. I would have appreciated knowing there would not be any real food available for purchase in advance. Otherwise a great experience. Thank you!

The flight was delayed but at least they let us know early about it (the night before)! Everything after that was smooth!

Our seats were changed 3 times in the final 24 hours, and then my wife and I ended up with two middle seats in different rows. Full flight so no changes could be made at the gate.

Air Canada was on schedule, fast, and took care of me the whole flight. With affordable price, I 100% recommend you fly Air Canada if you are able to.
