Same as the earlier flight. Bad boarding practices, uncomfortable seats, and no Wi-Fi service.

Everything was good. One of the flight attendants was not very friendly

Text and wifi were paywalled. I'm not looking for something fast, but not getting a text for ride coordination until back at the gate was a pain.

It was not a great flight. There was a software update delay which had us on the ground for almost 2 hours. I was unable to make my shuttle to my final destination.

Good. Quiet. Comfortable. The protests nearly kept me from catching my flight. They waited for me! I made it!

Red eye flight, so not expecting any extras, but the boarding and trip was smooth. Thx Alaska.

Received little assistance with air sick child. Crew’s main concern was if anything got on the seat belt!

I had to gate check my luggage and it was a pleasant experience as I never done that procedure before. Everything went smoothly.

Flight was excellent! Comfortable seats. Flew out of IND. very friendly crew!

It was fine… Just overbooked every seat was taken and very bumpy nothing they could do about that. Overall I like to fly Alaska airlines

Positive: Entertainment via phone on the short was great and my first time. Good food and wine and head phones for free. Negative: Seat hardly reclined on the long flight. Breakfast was an egg with a bun. No egg choices and rather have something sweet like bun/jam and Youghurt.

Aircraft has better leg room than any of United's larger planes. We had requested mobility assistance for this and related flights. United's response to all was superb.

No snacks served! Seating in the kast row in uncomfortable.

By in large it was a good experience. The flight crew was great and that's the most important to me. Boarding was fine.

Flight was fine, it was delayed but only 30 minutes, staff were efficient, lady making announcements at LAX was really hard to understand but the rest were great.

The male air hostess was rude and didn’t even offer me a drink. Poor customer service!

We left really late. Things that were out if anybody’s control I guess.

The weather caused a delayed but I was impressed how United did everything they could to try to get us out which included bussing us to the plane doing a Hardstand and bringing us to the plane since the fog was too thick to tow the plane from the overnight stay in the cargo area.

Food was really good. Chicken curry delicious. Great service. Had 3 seats, what a pleasure. What about a healthier desert option on the dinner? Yogurt, fruit? Thankyou

When I purchased my ticket, I assumed it was a real ticket, as in, when I go to the airport I am guaranteed a seat. Not so. When I checked in 24 hours ahead of time, I noticed I did not have a seat assignment and my boarding pass said "Standby." I was informed at the gate that the flight was full and I may not get on that plane. I don't recall being offered the option of selecting a seat when I checked in, and apparently, for the honor of pre-selecting a seat, you must pay an additional fee. So, a ticket really isn't a ticket, it's actually a lottery and if you're lucky, you may make it on board - or you can choose to be extorted for extra money for the guarantee of a seat. It's like making reservations with the Godfather - one payment isn't enough, there's always another bribe you have to make. After the first few zones were called and I hadn't been informed of my status, I went to the gate agent and they handed me a boarding pass, for the very last row near the restrooms, in between two very large people. Apparently that was my punishment for not purchasing a seat ahead of time. Airline service has not only gotten more expensive, but the return on your money has shrunk and there is little regard for the passengers. This feels like a racket. I am not pleased, as you may have gathered.

Cabin crew were great. Seats are criminal for tall people

My flight was great! Gate attendants and crew were great… pleasant and in good spirits. Flight delayed several hours and we were well informed of the status while on plane. Thank you!

The fact that I got to Toronto alive and well and safe is a huge plus. I thank the captain and crew for a safe flight The comfort of the aircraft leaves much to be desired. Human beings should not have to be that cramped and squashed on a flight that we pay a lot for and even have to pay for lousy food choices The cabin crew were pleasant and helpful Kudos to them as the flight was packed to capacity and there was a lot of work for them in a short space of time All in all a good experience, but too cramped

Overall I will say it was a very good experience. It was as comfortable as can be expected for such a long flight - 12 hours from Toronto to Tokyo. Everyone was very pleasant and polite. Even the passengers were cooperative and trying to be nice to each other. Of course the space is limited on such a long flight. The bathrooms were actually very clean. The food was very good. I liked how there was a variety of food options. The in flight entertainment system was also very impressive! There were some children on the flight but they were well behaved and hardly ever crying. Great Job Canada Air! I will definitely fly with Air Canada again!

Lost my bag. My first ever flight with them that they forced me to gate check my bag on, due to them having a 30 year old plane with small carry on bins, and they lost my bag. Never again.

The trip was fine and uneventful. The seat in business class was very uncomfortable which was disappointing given the extra cost. It was spacious but it felt like I was sitting on metal bars. The food in business class wasn't very good. The flight was ahead of time, the staff was professional and courteous and our luggage arrived safely.

Again we were late leaving Austin , there was no tv screen for the 3.5 hr flight, the pizza I bought was kinda bland

Both flights to and from Phoenix were delayed 2 hours each direction. Unacceptable. Disappointed with Air Canada I was given a food voucher fror trip to Phoenix but nothing on return. Both baggage claims took 2 hours to collect baggage

I didn't understand what "limited wifi" mean. Everything is money money money. I didn't have any other choice other than Air Canada since I couldn't find any other direct flight.

My flying experience with Air Canada was good but the wheelchair situation wasn't good at all and if would be good to make sure that they have the appropriate services available for your traveling passengers.
