Toronto's customs was one of the faster experiences I've had. They opened four more lanes to expedite the process when the lane got too long, to ensure we would all get through within around 15 minutes. The public transportation within the city is also top notch, in my opinion.

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

United airlines was top for my last trip in every way

Bad, they delayed my flight, lost my connection flight had to stay overnight for the next flight and missed a lot of important meetings. 1 day totally lost!

Boarding was quick and efficient which was nice and it was a nice treat to have a screen to watch a show for the quick flight!

airport arrival to Denver direction to where to go was not clearvfor Me.

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

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..

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

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.

The crew and the flight was excellent. Captain kept us informed about weather and possibly of turbulence and I appreciated that! The only thing is they didn’t have tv monitors. Other than that, everything was great.

It was an excellent experience, traveling from Toronto to Denver with United.

The boarding process in Toronto bad as they share space with domestic flights and when those domestic flights come in you are locked out behind closed doors until they are done and then its a mad rush to get your boarding gates and board. This is not so much due to Air Canada but with the GTAA, but Air Canada could use different gates especially early morning in order to prevent such travel angst.

Fight left late making it extremely hard to make the connection. Flight staff was pleasant and efficient.
