Greetings when you arrive on the plane and good bye when you leave. Very attentive flight attendants.

Serve me a meal, I fell asleep during the flight. So they passed me twice.

Seats are not table comfortable. Crew members are pretty good. Can be much better!!

Very pleasant overall, although the movie selection could have been better.

Very pleasant experience overall, while the main course of the meal could have been better and the movies could have been more recent and with more variety.

I usually have ear problems when planes land. But the landing was so smooth I didn’t even notice it landing! The service was excellent!

the aircraft was fine and new. The crews can have better training. Their operations are not as smooth as EVA's. They are VERY stingy with drinking water. Throughout the entire flight, no one offered me any water and snacks. I still prefer EVA after trying out Starlux initially with lots of excitement and expectations.

Everything was smooth and professional. They could improve the raw vegan meal with fresher offerings, but otherwise they are now my favorite way to fly to Asia.

Leg space is small. Need more room for long flight.

Leg space is too small. Need to increase space for long flight.

Good flight, friendly crew and overall - good service on United Airlines.

Received email saying that there won’t be a seat back entertainment screen and inflight WiFi would be available. But no WiFi both ways. Say it in the email.

Somebody either kayak or Air Canada booked my flight under my preferred name Betty instead of my legal name and I almost was denied boarding my flight

flight landed late almost 1.00hr and we 4 passengers missed our connected flight to indianapolis, we need to get the hotel and taxi for the next day flight to home in indianapolis, cost us $ 300 more

Or the greatest and it ended up picking us up from Chicago to Toronto not sure who was tesponsible for the 4 hr delay. United should have been properly prepared for a scheduled flight from Austin to Chicago and they were not.

Good, only discomfort was consistent turbulence through the 3 hour flight. Not sure if in companies control though.

I’m writing to share my deep frustration with a recent experience, which I feel reflects a troubling trend in the airline industry—one where customer care often takes a backseat to profit maximization. First, I do want to acknowledge a positive aspect: I appreciated that your team accommodated a seat change due to my medical needs without charging an additional fee. This gesture made a genuine difference during my trip, and I’m thankful for that. That said, the overall experience left me extremely disappointed. The ticket I purchased for myself and a companion turned out to be “basic”—a fare category I now understand to be non-refundable and non-transferable. Unfortunately, my travel companion was involved in a car accident and could not fly. Not only was I unable to receive any kind of reimbursement, but I also couldn't transfer the ticket to someone else, despite the flight being overbooked by three passengers. This inflexibility felt exploitative. To add to the frustration, I had to shoulder additional unexpected expenses: overpriced in-flight food and a costly baggage fee on my return trip. The entire process felt more like a profit-maximizing scheme than a customer service experience. I understand that airlines, like any business, need to remain financially viable. However, creating fare structures that penalize customers during emergencies, while simultaneously overbooking flights, comes across as deeply unfair. It’s hard to feel like a valued passenger in this environment. While I don’t expect much will come of this message, I do hope Air Canada takes this feedback seriously. There’s an opportunity to lead with integrity in an industry where choices for consumers are becoming more limited and experiences increasingly transactional.

From the kind young lady (w/Vancouver air security) who expedited our check-in to U.S. Customs to the Air Canada gate crew who gave us pre-boarding, the flight attendants who actually offered a strong hand to help me board once I had surrendered my rolling walker at the door, they are all reflections of the thoughtful, genuinely helpful Canadians we have grown to appreciate. Water and other beverages were offered throughout the flight to make sure we weren't dehydrated and the cookie was great. (Husband bought the fruit & crackers snack,) I was delighted to see three movies that I would not have otherwise seen and appreciate that AC left the last film viewable until its conclusion although the flight had actually landed. Last, mahalo to the kind strong gentleman who not offered his hand to help me debark the plane, but gave me an AC pin that I'll truly treasure.

The ground staff was so rude in Toronto airport ...very rude and did not answer simple questions, and made me look like a fool. Very rude ground staff.

My flight got delayed 5 times and then got cancelled eventually, I had to get a hotel and uber and pay for food for an extra night without any plans. It was a horrible experience, instead of Air Canada, I was flying with United .
