I was supposed to be on business class at first class from Denver back to Miami due to weather changes. I missed my connection and it’s put on a flight to Fort Lauderdale. Instead of honoring my business class/1st class ticket, they put me in coach, but there were two first class seats open. I think it’s absolutely disgusting that I paid for first class $1300 ticket and they put me in economy and they had to open seats available and I have still not been refunded the difference. I ended up having to eat a snack box instead of the meal I was supposed to get and did not get home till 2 AM so I think that’s a little pathetic that I had to live off crackers for dinner And my poor dog ate some cheese and salami. Oh yes, apparently when they switched me to the new flight they forgot to mention I had a service dog

The boarding of took of late.The presentation of the food was horrable as was the tast of the food was cold and tastless.

Liked fold flat bed. Didn’t like having no window. Didn’t like poor choice of food and being served dinner very late, hours after take off of a 7:40pm flight. Servers not friendly. Food horrible in business class.

They switched out gate from terminal 1 to terminal two ten minutes before boarding. So we had to make a 20 min crazy fast walk to a different terminal. Then we boarded the plane and waited for over 40 minutes until push back. Brutal

Easy to board. Flight was super crowded though so I didn't sleep well on that cross country red-eye flight. The aisles seem ot have gotten narrower and the seat smaller whn luggage and people are getting bigger so it would be AWESOME to have more space and breathing room in general ;)

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.

Fight was delayed an hour due to operational issues ,then further delayed due to ground control for a total of about 1.30 hours. Salad was completely frozen and flatware was so cold you could barely handle it. Crew was friendly and professional and the flight was smooth. The aircraft was clean and well-serviced.

The flight was delayed, it took longer than anticipated because of weather, and they broke my luggage.

Food is terrible. Flight is outdated and seats are not comfy.

The aircrew was solid, the flight was chill, I had no issues. The gate agent was not the best. I was trying to use a military bag upgrade to move my bag from under the seat to the overhead bins and he told me there’s no overhead bins on the plane, argued with me why booking put a military member in basic economy (I don’t really understand this) and made it an issue to even try to help me stating I’d have to call reservations to get a bag upgrade. When every other agent with United can add it at the gate, this man couldn’t be bothered.

The seat was reasonably comfortable. I hope the food could be hotter and more tasty.

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.

There is not enough space between two chairs and raws.

From my experience, I see there is room for a greater mixture of cultures, for example, a mix of the nationality of cabin crews, food, music, food, etc.

on time quick service but food so so and seats very small. no leg room. I think passengers should not be bringing so large carry on suitcases and should have free check in. Then boarding and unloading would be faster

They are a great airline, and i enjoying flying with them. However my experience with booking through Kayak was a horrible experience. With all the restrictions and glitches of website. My entire bookings by kayak was wrong. And there was no possible way of fixing anything with them, because they hand over responsibility to the airline after purchase is made. Will not be booking through Kayak again and will inform my family and friends not to as well.

After nearly nine years without traveling, my son and I decided to take our first flight, and we chose Air Canada and I’m so glad we did! From start to finish, our experience was nothing short of amazing. The flight itself was smooth, comfortable, and truly enjoyable. The staff were warm, professional, and went above and beyond to make us feel at ease. But what really stood out for me was the luggage tracking feature. Knowing that my bag was scanned onto the same flight I was on gave me such peace of mind. It’s little details like this that make all the difference, especially after not traveling for so long. This trip was incredibly special for us, and Air Canada made it even more memorable. Thank you for such a fantastic experience I wouldn’t hesitate to fly with you again!

Terrible. They boarded us and then we sat at the gate for 2.5 hours. Our flight overall was delayed 6 hours.

I was not even asked if I want some water. Joke. Steward gave me a biscuit cover in chocolate and did not even look at me.

This was an Air New Zealand flight. All went very smoothly even during the busy Christmas travel period. Thank you!

Food was terrible, tasteless. I ordered ovo lacto special menu in business class and got vegan tasteless food instead. Really disappointing.

From boarding, to attention in flight, I couldn’t fault it.

I was in business class for the 8 hour flight where: 1. The WiFi did not work 2. The entertainment system did not work 3. We were told there were no hot drinks for the entire flight

The flight was delayed twice. When the crew explained about the debris causing flat tires, I was glad they took the time to change all four.

Flight delayed Service could be better Iberia staff are not really friendly

They cancelled the flight)(they said bad weather but many other flights took off) and made us wait 5 hours in line to figure out what to do. We ended up making a new flight the next day on another airlines...I hope they honor giving us our money back

Awful. The flight wasn't actually operated by Iberia, but by American Airlines. I was unable to get my boarding pass and as a result missed my connecting flight.

The seats were way too crowded. Just because I do not have the luxury of a suite, does not mean that I want to fly from Austin to London scrunched between two people and the seat in front of me in my face. Ridiculous. I should have flown with Turkish Airlines...

We travelled with Level, which is a subsidiary of Iberia. They mixed up all our seats, downgraded few from premium economy fo economy. The crew were not professional, they seem to be in a rush! Also some with an attitude

Paid for “extra room” selected seat. Wasn’t a benefit. Also was in aisle and was bumped almost every time attendants walked down aisle. Should have saved the assigned seat money and let them select.
