We were given vouchers we couldn’t use with a 5.5 hour delay

I fly UAL 7-8 times per year. This flight was not up to snuff because it boarded very late "due to unexpected delays in restocking the plane" and yet Flight Aware showed the plane had landed some 10 hours earlier--so I think they could have planned accordingly. The FA's were nice but harried. The video system had to be rebooted 3-4 times. The food service was rather abrupt; they forgot my row and when I asked for my meal, they brought it with some impatience. Overall, the flight was fine, but the little details made it feel somewhat mundane and hurried.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

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

We were delayed in Toronto on the tarmac for THREE hours with no clear indication as to why except that it was not a safety hazard. Pilot did apologize more than once but even he was unable to explain why exactly we were delayed. I overheard the stewards saying that the captain was very frustrated with the situation as well because he was not able to explain why except it had something to do with water supply or system on the aircraft and now we needed to wait for an engineer to approve the aircraft for flight. It was very frustrating and distressing as a passenger and we should have been given complimentary meals at the very least.

Flight was cramped with every seat taken. The food was fine, nothing crazy to write home about. The plane felt dated and needing some TLC, the button for the window shade didn't work and there were no AC outlets to use. When communicating with staff all except one nice lady never seemed happy to help me almost like I was bothering them when asked for things like a glass of water or a snack. The flight was overall fine. It did what was needed which is get me from point A to point B. But it certainly was not special. I don't expect much in economy but I believe economy on a host of other airlines is more memorable and better experience.

The flight was heavily booked so boarding was a lengthy process. The FA’s were rather abrupt during this process but became more gracious as the flight went on. Breakfast (puffed pastry and chewy sausage) was pretty horrible but there was fruit and yogurt which they didn’t mess up. Overall it was fine.

Liked nothing. As per previous segment it was delay delay delay.

I completely missed my flight because the first leg was longer than planned. I had to sleep overnight in the airport because no accommodation was provided and then sent to Trinidad in the morning with an anticipated 7 hour layover before my flight to Georgetown which was now with Caribbean Airlines. I tried twice with customer service to see if they could put me on an earlier flight which had seats available but was told it wasn’t possible.

the seats aren't the most comfy -- too little padding and I could feel whatever the passenger behind me was doing. Otherwise, it's all good.

This flight didn't happen for me because of overbooking.

Everything was simple and easy. The lady at the gate was super friendly, I wish I had her name to share. She's a little older, dark-haired. You can tell she likes her job and would be a great influence on any young people training with her.

During the pre-departure safety briefing, the flight attendants rushed through the mandatory safety announcements in both official languages, making it difficult for passengers to clearly understand the instructions. Given the importance of these messages for passenger safety, this lack of clarity was concerning. Perhaps use a recoded message to alleviate this concern. Additionally, the flight attendants appeared to lack the professional attentiveness typically expected during a flight. Rather than focusing on timely and courteous service, they seemed more engaged in personal conversations than in addressing the needs of passengers. I hope this feedback is taken constructively and helps in maintaining the high standards of professionalism and care that travelers expect from a national carrier: AC.

Service is pretty good. Sandwiches have to be purchased but I’ve bought my own food. Seat was comfortable and various movies to chose from.

The flight was delayed at the last moment quoting an absurd weather reason. This delay led to an issue with my connecting flight. I was made to run (literary) from this flight to the next one ( as they preponed departure. I was still in my DCA to YYZ flight when the boarding started for the next connecting flight. After my sprint to get the connecting flight, found that no place for my carry on. Had to sit for 3 hours with my back-pack on my lap , it was the most uncomfortable and inconvenient journey with little to no empathy shown by cabin crew in both flights. Another poor show from Air Canada!! Cant help because of lack of options !!

One leg of the flight arrived late which necessitated a rebooking on the next leg. Although there were no major weather events in play, best choice offered was a 7 hour wait in the Vancouver airport for a 4 hour totally packed red eye flight to Ottawa. No opportunities to return earlier via other major hubs like Toronto or Montreal. Felt very much like national routes were no longer well supported. Adding insult to injury, entertainment system for my seat was out of order. Thought I might use wi-fi, but discovered it would cost $10 per hour! Paid a lot for the flight as it was over the holiday period. Probably won't be doing that again.

Made me check my carry on despite there being dozens of empty bins when I boarded which significantly inconvenienced me.

Your survey should include a "Not Applicable" response for those elements that were not utilized, such as food (unless your want me to rate the cookie I received) and the entertainment (unless you want me to rate the emergency landing presentation). Boarding was late, the plane took-off almost an hour late, and the gate to board changed five times while I was waiting there. At 1:00 pm the plane had not yet approached the gate for passengers to load, yet the information board indicated that the take-off would be 12:30 pm and its status was "on time". Curious.

The people are great! The trip to Japan is simply never ending!!! Not the problem of the airlines, though.
