Terrible boarding - 4 flights boarded from the same gate. Chaos there; long ramps to the plane.

Flight delay in lax which delayed our connecting flight to Copenhagen. Was placed on standby the following day and got delayed again at Scandinavian air. Bad bad counter service at ar Canada in Toronto by the name of Camilla who said that she was doing us a courtesy for even finding a earlier flight for us after we the customer are the ones being inconvenient by the cancellation of our flight. Btw, we are going on a tour. Air Canada is the worse

The flight itself was ok, but one member of the crew was miserable

Fine except from Chicago to moline three different gate changes and flight times

No complaints other than luggage carousel was incorrectly guiding passengers to the wrong carousel on the screen.

The flight crew on this leg of my trip was very friendly and pleasant. Every one of them was humorous, as well as helpful and accommodating. This group was BY FAR the best crew I’ve flown with. They deserve kudos.

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

It was a good flight. Nothing comes to mind about how it could have been better. It was a newer plane, seemed like a great upgrade from your older ones. Staff was very good as well.

I had very little time to change planes originally in Denver after my flight from Omaha. I had an hour and a half layover in Denver originally and my flight leaving Omaha was delayed an hour because they had to change a tire, which I can understand. When I reached Denver my other flight was late, fortunately, but I still had only 10 minutes to run about a mile through the airport to get to my flight. Again, fortunately, I am a healthy 71-year-old and was able to accomplish this feat. However, the stress was more than necessary to bear.

The amount of seating is ridiculously small. Three points to consider Point One: Your in flight magazine needs to be smaller. Do you realize I can't even hold it in a reading position because of the limited space in front of me? It's a hangover from the past and if you want anyone to read it, it must be smaller. Point two: It is very uncomfortable for a lady to be sitting next to a strange man and constantly rubbing upper arms even when both of our elbows are within the arm rests. And larger men (whom I pity in this confined predicament) also tend to spread their legs into my leg space which requires me to hold my legs into a smaller position. Point three: The seats seem to position one's body in an unusually upright manner and the head rests push the head farther forward. I gave a small effort to see if the headrest could be removed but didn't want to break it or cause a scene with my efforts. I finally put my jacket behind my back to place my body more forward to match the head rest. The service was fine and I noticed ALL staff worked at smiling and greeting passengers. That was nice. No one likes to fly anymore as it is an endurance rather than a pleasure.
