I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

I've flown many many times on Northwest and then Delta. The crew on this flight were absolutely the best I've had the pleasure of being looked after by.

Flew first class so everything was great. But maybe because the flights were red eye, no meals were served, just chips. I flew Alaska Air 1st class at 9PM (2 hour flight) and they served beef short rib sliders!

Had to change aircraft due to a faulty door. Surprisingly it only caused about an hour and a half of delay. Delta handled this situation as well as can be expected.

Awful. Flight was continuously getting delayed and gates kept changing without any reason. Flight was delayed for more then 3 hours

Paid premium for Delta only to be on safe but tired old 767 with ancient cabin in mediocre condition. Poor wifi and horrible inflight entertainment. Hardly a premium experience. Should have flown SW and had fun flight crew and no pretense

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

Half the bathrooms assigned to economy were out of action

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

The Priority check in in Toronto rivalled the poorest I've experienced. The young woman at the desk (7:30 AM, YYZ) was unfriendly and abrupt, behaving as though we were interrupting her day. Her inch long fingernails said it all....I really don't belong here. Other than that, WestJet personnel provided a good travel experience, especially in flight. I must say that the repeated announcements about the cabin being full and how folks should gate check their bags became tedious. WestJet should just offer free checked luggage and charge for carry on suitcases. It would save a lot of time and the voices of the gate agents.

Wish there was an option to book a fellow traveler who is not necessarily paying on the same booking. Then the airline could consider placing us together. It was a long flight to be separated from travel buddy. The first meal, a luncheon I think was ok with warmish pasta and a tiny salad. The second meal, a midnight snack (hard to say because of the time change) was really awful pizza fold-ups, and no option for folks who cannot eat cheese.

It was a 35 minutes flight. Didn't expect much. You should add a 'not applicable' option to your survey.

The back seats are crowded and at times uncomfortable. I guess that’s part of the price of paying less for a seat.

My journey from Rome to Seattle contains two parts, first from Rome to YYC then transfer YYC to Seattle. First part from Rome to YYC was wonderful. Fly on times, easy boarding and comfortable seating and good meals. Second from YYC to Seattle is terrible, delayed three times before boarding. No meal, no water, no entertainment. Landed in some corner of airport , walking in bitter cold night and taking the bus. My friend told me that Westjet is the best airline in Canada, I doubt it

They lost our luggage and didn’t return it until 15 days AFTER we got back.

Adequate though food was not great and no alcohol abailable

Great Experience! Flight was ahead of schedule and very smooth! Wonderful flight

For some reason there was a change in the cockpit which delayed us by an hour

flight changed by airline. then could not check imto mew flight because kiwi had messed up the reservation. still waiting to depart…

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

Should have video screens Plane audio was poor and without wired connection hard to understand crew. Should serve more than just cups of water and pretzels on six hour flight. Did not see crew rest of flight. Fix charging sockets to retain charging blocks.

Food was terrible Not many options Stewards dont care Delay

The ride was good but no food ot entertainment hence, it was just over an hour flight.

they made me check my carryon. There was space in the overhead bins.

The plane was delayed 2 hours. The wifi did not work. The seat in first class was not comfortable because the bottom felt like it lost all of its padding. And I did not like when the flight attendant made me wait at my seat to use the bathroom and didn't tell me why. If there were too many people using the 1st Class bathroom, she should have told me to go in the back, coach bathrooms. I guess I have to feel fortunate that they found 2 local pilots to still fly the plane tonight after the original pilots ended up at an airport 60 miles away due to high winds.

The crew were really great, but the 4 hour delay in small chunks was the worst.

Every experience was good except for the lack of comfort in those economy seats. I never had knee pain until that flight. Those seats are uncomfortable.

I bought internet for the flight. Don’t waste your money. I wasn’t able to download a 1 Mb file from Google Docs during a 3-4 hr period. You can only use WhatsApp and email if you are willing to wait.

Just a crappy airline. The same every time. You feel you are a cow on a farm. You are being being whipped and pulled.

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!

Flight was delay for 3hours then later canceled. I missed my work. It was a bit ectic and frustrating

Made me check my carry on and then lost it,

Air Canada staff was very good. They were very pleasant and attentive. As I was boarding the plane the aroma from the coffee hit me, I then said a cup of coffee would be nice. Well, when it was time to serve and the flight attendant got to me seat, she said 'Mam how do you like your coffee ' she remembered, that was nice. The little things in life that can put a smile on someone's face.

The flight ran out of hot meals for the back half of the plane and gave us tuna sandwiches. Not okay, these flights cost too much to short us the experience!

Affordable & comfortable. Not sure why a party of two I booked at the same time got seated separately.

Pretty much as good as an economy flight experience can get

45 minute delay take off. Entertainment system froze half through the flight.

This was a bare-bones flight on a small plane. I chose it for the good fare and the fact that it was nonstop. No entertainment and just beverage service were fine on this short haul.

Our plane was so cramped that I couldn’t fit my bag below my feet and my knees were pressed against the seat in front of me. For a 45 minute flight, We sat on the runway for over an hour before returning to the gate to wait for another 2 hours. We arrived over 4 hours late, uncomfortable and tired.
