Boarding was smooth and efficient. The only food was some pretzels, but it was a short flight. Not much to order if you were hungry.

Boarding was smooth and efficient. The only food was some pretzels, but it was a short flight. Not much to order if you were hungry.

They were fast and I like how they used to entertainment system to play video about the safety.

We Left Calgary 1/2 hour late and that made for a tight connection in Denver. After arriving everything was done to help us make our connection. That was a great effort. Thank You United

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

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

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

It was 4 hours late. Almost missed my connecting flight no food or drinks on connecting flight. Overall terrible experience

United airlines was top for my last trip in every way

Horrible; seating was atrocious - inadequate leg room and seat width tight even for a small individual. Profits shouldn’t be everything!

I flew basic economy, so it was what I expected. Crew was nice though, and flight was quick. Would recommend for flights under 6 hours, otherwise would upgrade to something with more leg room.

Our itinerary included a 1 hour and 30 minute layover, which should have been sufficient under normal circumstances. However, our original flight was delayed. Before we even deplaned, we were instructed to collect our checked bags from baggage claim, clear immigration and customs, and then recheck our bags for the connecting flight. The airline knew—or should have known—that this was impossible. Checked baggage acceptance closes one hour before departure, meaning there was no realistic way for passengers from the delayed flight to recheck their bags in time. Despite this, the airline gave us misleading instructions instead of informing us that we would likely miss our connection. We completed immigration and customs in approximately 10 minutes, but our checked bags did not arrive at the carousel for more than 30 minutes. After collecting them, we had another 10-minute walk to the baggage drop area, only to find that no airline attendant was present. We then went to another airline counter, where an employee told us this had happened before and that there was nothing they could do because the baggage acceptance window had already closed. At that point, there were still 40 minutes remaining before our flight's departure, yet no one was willing to assist or offer a practical solution. When we asked to be rebooked, we were simply told to call the airline's 800 number ourselves. There was no accountability or customer support at the airport, leaving us stranded in a foreign country with no immediate assistance. After finally reaching an agent on the 800 number, we were rebooked on a flight for the following day. However, we were initially told that the airline would not provide any hotel accommodation and that we would have to arrange and pay for it ourselves. Only after making multiple calls and speaking with several different agents did one representative finally issue a hotel voucher. The entire experience was an exhausting and frustrating ordeal. What should have been a 20-hour journey ultimately became more than 30 hours due to the airline's poor planning, misleading instructions, lack of accountability, and inadequate customer service. The unnecessary delays, confusion, and absence of meaningful assistance caused significant physical exhaustion and severe mental stress. This experience fell far below the level of service passengers should reasonably expect.

Despite travelling ultra basic for the first time due to such increased rates we both managed with one bag each. Even boarding last wasn’t SO bad.

I loved the fact it was on time and it was a smooth flight to my destination.

Service was okay except attendant over served alcohol to passenger and passenger got tipsy and made me uncomfortable

Could not make the flight. No one would help us at all

The window seat on the emergency row was too small. I had a different seat booked and they moved me. My seat remained open. It was very uncomfortable.

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

Flight delayed 3 hours, missed my connection in Atlanta. Instead of getting to Savannah at 6PM arrived after 10:00PM Middle seat, couldn't get isle or window, couldn't book my seats in advance, had to book at the gate. That's a 1st for me and I used to travel a lot

Technology issues at the bag-check counter caused a delay, and we were unable to check out our bags, ultimately missing our flight. They offered no assistance other than telling us to book another flight out of Calgary. We arrived with plenty of time; if there hadn't been an issue with the kiosk and the length of the lines due to the technical issues, we could have made it home.

All was good except that the option to purchase wifi for texting throughout the flight didn't work. My partner and I both tried via the app, Chrome and Safari, we tried all payment options. Nothing worked. He was able to get ok blonde with he full coverage option, but it's nice to what we wanted or needed.

Another good flight experience with Air Canada. The business section did not feature the full length sleeping arrangement, but this was a shorter trip. The food was excellent. But the flight crew was truly top tier: friendly, cheerful, helpful at all the right times. Air Canada truly outshines all U.S. carriers.

Wifi was great. Kind air crew and comfortable seating. Also liked the entertainment options.

I did not noticed baggage was separate - I had assumed international flights included luggage, so it surprised me I had to pay to check a bag.

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..

flight landed late almost 1.00hr and we 4 passengers missed our connected flight to indianapolis, we need to get the hotel and taxi for the next day flight to home in indianapolis, cost us $ 300 more

Overall good experience. The flight from Toronto to Denver does not have entertainment - movies to watch.

The only issues I have are the seats are very small and so is the overhead storage. You should mention that while booking flights. I had plenty of knee room but I am wider than my seat, and I am not fat at all. The Mitsubishi 900 models need to be upgraded to western size people. I do not know how a 300 pound woman fit into those seats. I had to continuously lean away from the aisle to keep people and flight crew from bumping into my shoulder. 3 hour flight so no entertainment or food, just snacks and a drink, which was no big deal. The buttery/garlic pretzels were pretty tasty.

I was overcharged either by United or sister airline Air Canada. It's exhausting dealing with companies nowadays that irresponsibly abuse access to credit/debit cards.

The flight attendants that assisted me were exceptionally nice, kind and helpful

Very good. But seat selection was not good. We were put on different rows. Would have been nicer to sit besides each other as a couple.
