They messed up my seat so I didn’t get the one I paid for

They messed up my seat so I didn’t get the one I paid for

Put me on standby; flight was late; missed my connecting flight; disaster

Flight attendants were fine, seats a bit hard but I use a cushion for extra support. The only issue was it was a bit too cool and I needed to ask for and received and extra blanket. I survived!!!

Very few things and/or people are excellent. It was very good.

Extremely uncomfortable seats. Experience was like a Frontier Airlines flight. Would not fly it again.

Very, very tight legroom. They must’ve jammed in an additional few rows of seat seating. Denver to Munich was the least legroom I’ve ever had on any flight, let alone a multi hour international journey. I will not take that flight again.

Never made it to Lufthansa because of Air Canadas negligence.

In my first flight with Air Canada we sat in the plane for 4:00pm to 6:30pm. Finally we were asked to get off the plane and we were told the flight was cancelled after 7:00pm There was o clear explanation of what was the problem. I was booked without my permission on a Delta Flight at 7:30pm that was leaving at 8:00pm and I still had to go get my luggage(my final destination was Rome with one stop in Toronto. The luggage claim for Canada was closed so had to return to finally get it on the luggage belt.. Of course I missed the Delta flight and all the next day flights were booked. I also lost what I paid for my stay in Rome because I did nt cancel in time. A complete nightmare.

Good food, overall very comfy. The flight was full so obviously not optimal, but it is what it is.

Perfect airline, super friendly, great service, tasty food. Would fly again.

ITA has these new Airbus A330 Neo that hates economy class passengers. The seats have absolutely no cushion to a point where it hits your spine constantly and reminds you to fork out for premium economy or don’t travel next time. The food was absolutely horrible, ETA mentioned 3 meals for 12 hour flight but it was mostly 1 meal and 2 light snacks. I am vegetarian, so my 2’d food was 1 slice of tomato, 1 cucumber on a dry cold bun. The other 2 meals were disgusting. My young one threw up the entire time. Flight attendants were the cherry on top - plain bad. They would skip servicing drinks to some passengers completely and if you call for an attendant, they will come and stop the button on top without even asking you what you need. I would avoid ITA by all means - there are plenty of options including SAS for same routes with better seats and humane treatment.

Nice flight. Uneventful, very good crew, comfortable seats. Pleasant experience.

Stews were nice. Plane was very old. Some of the mechanics for travelers outdated. Not enough bathrooms. Hideous food.

Our flight was changed to a day we could not travel so we cancelled it. Will never use kayak again

Comfortable flight Attendants are professional Had a luggage delay at one destination but was delivered the next day

ITA cancelled fligh rebooked with Lufthansa. Flight good, but 2hour connection in Frankfurt was HORRIBLE, took 1.9 hours to get through scanner, customs, another security, got to gate after running all the way, so caught it but stressful and terrible start to trip.

The boarding process was organized and efficient, and the crew was friendly and attentive throughout the flight. Food and drinks were typical economy class, but good. The aircraft was old, and the restroom was not very clean. However, we arrived on time, so overall the experience was good.

In Prem Econ, safe and timely flight, good amount of space, mostly comfortable seats. Little irritants: When lying down, seat kept shifting on me...as a short person w/light weight, my seat often reverted to semi-upright. Footrest was broken. TV screen didn't work, after I asked a few times a FA rebooted it to work again. And food was marginal. I don't expect much from airplane food...surprisingly, ITA didn't even meet expectations.

Flight was canceled. Rebooked on Lufthansa Also Canceled. Had to pay 3000 more per person and fly Alaska to EWR and fly emirates to Athens.

Our flight was cancelled the day before our trip and we we put on a Turkish Airline flight that got us in half a day later.
