I found the staff to not be very attentive at all. When paying for Business Class you expect a certain type of service and that was not found. They were almost rude even

I found the staff to not be very attentive at all. When paying for Business Class you expect a certain type of service and that was not found. They were almost rude even

the delay for 3 hours was understandable due to weather conditions but the flight should’ve provided some on flight compensations or at least provide more food.

Flight was actually on Air Canada. The flight itself was fine. Nothing special. Food was pretty pathetic except for cookies. They offered plenty of food and drinks but just wasn't very good. Even for airline food.

Boarding experience was smooth. Flight attendants were friendly and helpful. Entertainment system on the Houston-Edmonton flight did not function for passengers on the left side of the aisle. On the bird's eye flight from Quito to Houston, they should not serve a meal. No one needs to eat after midnight and it is disturbing for those passengers trying to sleep.

Flight was late as pilot crew had to land at different airport in their previous flight. Passengers boarded and had to wait for pilots inside plane. Series of incomplete and unnecessary announcements by an annoying voice, rather than complete, informative announcements.

Delay and keep changing gates. I have to run around from B to C then to E.

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

My suitcase was completed destroyed. The top part is broken and unusable now.

When I booked it on Kayak it aaid that I wasn't allowed hamd luggage. I called United Airlines and it took them 6 minutes to figure out if I was allowed free hand luggage. Surely something that simple they should be able to tell me instantly.

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

Liked getting into Milan at 10 AM. Also ok to get into LAX at 9:35 pm. - less traffic driving home. Layover a bit long - say 3-4 hours each way. Montreal airport kind of grim these days. Would lose the duty free area. Think art versus advertising. Maybe local shops and food spots. And keep layover short - like 1 hour on Finnair in Helsinki.

Upgraded to sit at the exit door so good leg room.

I had a good experience. I liked being informed about the status of my luggage

Orderly boarding. The flight to Montreal was difficult to get to on time, but had help from staffer.

The food on this 5 hour flight was a cookie or pretzels.

My light was not working, I requested a meal without carrots( due to an allergy). It was not provided, so during the 13 hour flight, I was only able to consume bread and a small fruit cup. The air host was not helpful at all.

In-seat entertainment was great. Gluten free food options were very good and they gave a lot of food.

Staff was very courteous and kept things organized. We will definitely use Air Canada for further travel

I am very tall. All airline seats are a bit uncomfortable.

There were a lot of empty seats so we were able to spread out and be more comfortable. The food was decent enough. The crew, however, there was one flight attendant who put a hand on my grandson as he was walking to the bathroom and told him to stop. He’s 13 years old and didn’t need an escort so I don’t understand the necessity of putting a hand on his chest and saying “stop”. My grandson was confused and embarrassed with no explanation.
