Latam wouldn’t tell me how much checked luggage would until I was at the airport and they charged me the highest price possible. Besides that, it was okay.

Latam wouldn’t tell me how much checked luggage would until I was at the airport and they charged me the highest price possible. Besides that, it was okay.

Check in -- in business took over 30 mins as there was only one attendant. Boarding was also a mess. The seat was too narrow and was not working properly. Food was very bad and the entertainment very poor. Crew was very polite and helpful, in fairness.

The plane broke down at the Lima stopover and they offered to put me on a flight the be t day but I had to be back in LA that morning and so I had to buy another ticket from Avianca and United for $2k I asked LATAM for compensation and received none. Very bad experience

Change of gate in Santiago devolved into half plus hour delay and a really tight connection in Lima

They didi not provide wheelchair though we had requested. We had to run around for 40 minutes and arrange it from the airport!

Everything was good except the check in. Could not do it online neither on the machines in the airport. Needed special assistance from the airline desk clerk

Great customer service, very accommodating. (Check in) Smooth flight, thank you Pilots. Only negative was one working bathroom in first class. Atlanta Base flight attendants were wonderful. Thank you for your smiling faces Delta..

The seats are getting smaller and smaller. Very uncomfortable trip. More than in other airlines

I do not speak Spanish or read in Spanish When asking for help, people were hard to find they spoke quickly and pointed a lot directions for where to go and what to do we’re unclear. Which made my traveling uneasy.

I do not read or speak in Spanish. Only English. When asking for help, the people spoke quickly in English and pointed a lot. I wish they would’ve spoken a little slower for me to understand. There was much confusion and hurried in their message and I was unclear as to where to go

It was great to have a vegetarian meal option, but departure was delayed because they had oversold the flight. Air Canada, you’re in charge of how many tickets are sold: don’t oversell!

I liked the quiet airport and no queue. I don't like that when booking it is not clear that there is teared economy, that you have to pay extra for choosing a seat and for your luggage both ways. We didn't find this out until checking in. It turned out not very economical.

I hope they were able to assign my preferred seat on my connecting flight. Wasn’t sure if it was language issue or they just can’t.

In flight entertainment system did not work across the whole plane for entire flight. Seats were very cramped. Cabin temperature was freezing cold. Crew was miserable and answered everyone in a short and barking manner. I’ve flown air Canada many many times and never had an issue. But this was unpleasant.

They screwed up so bad, I asked for a short check for my luggage since we had a 21 hour overnight layover in London at a hotel. They said I have to receive my luggage in London because it’s an overnight layover. Get to London, nope, my bags aren’t coming off they are staying in terminal 5 over night and going straight to Ibiza. So we had no luggage for a whole day and basically stuck with no clothes or washroom stuff. Finally get to Ibiza and my luggage is completely smashed and damaged and missing a wheel. Now I have to drag this 50 lbs luggage around Ibiza islands for 10 days. Wtf. So pissed off Air Canada is LITERALLY THE WORST AIRLINE IN THE WORLD

Great flight ✈️ I requested a vegan meal and don’t think offering frozen fruit cup for breakfast is a good idea people want something warm or neutral like the muffin but it was cold from being in the paper bag with the frozen fruit 🧐 and unfortunately I didn’t have either and I don’t like wasting food so that was a disappointment. Flight was on time departure and arrival flight crew were good.

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

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!

Was good all around. Crew, food, paid for extra legroom, as 10+ hour flight Like the 787 as I don't have any problem with my ears, due to the planes pressurization.

Comfortable seats, good service overall. The food could’ve been a little bit better. The boarding process was slightly chaotic and in fairness, not all of that is related to the performance of British Airways.

The chairs were a bit tight even though I had extra feet space…2nd plane didn’t have entertainment and even though they said there was free WiFi-I believe the free WiFi wasn’t accessible unless u had some account set up….which I didn’t figure out

On time. Comfortable sats. Clean aircraft. Friendly crew. Good food.

Naples airport not the best ! Boarding via coach to aircraft never the best. Staff and captains announcements good. Flight on time with soft landing. Ran out of sandwiches half way down the plane. !! Not impressed. 7/10 satisfaction overall

The seats are not comfortable if you are not tall.

The flight was cancelled and I was re-routed via an inconvenient routing proposed.

Overall great! They could add more entertainment option. They kept running out of vegetarian food options and I got travel packs. This happened on all legs of the flight. Need to plan for it better - I am sure you have some data analytics from all your travels.

Better service to offer drinks in the middle of the trip

They can improve Everything, a 12 hour flight has just 2 meals and the meals are 7 hours apart, wtf are they thinking. At the very least they should have 2 refreshments like some small snacks with some water or some other refreshments since there are people travelling with medical conditions. The services and seats were genuinely horrible

As I remember my last BA flight - mediocre at best. Uncomfortable with poor and minimal food and drinks. Screen broke shortly into flight so didn’t have access to entertainment either.
