I have never been a big fan of airplane meals

I have never been a big fan of airplane meals

We purchased premium economy seats 9 months ago and got bumped to economy when we tried to board the plane. It was a huge fiasco while they struggled to find us seats. I tried reaching out to Kayak to see how we can get refunded for the extra money we spent on premium but have heard nothing back. It was a 14 hour flight and were disappointed that we lost our seats after selecting them 9 months ago.

Flight was overall OK: lovely staff and smooth travelling. The only downside was no food was available on a 3.5 hour flight over lunchtime. Luckily we had realised this in advance and brought our own bento.

The whole flight in Economy was great, the crew were just amazing and the food was great as well

Crew went out of their way for me, not often

Lots of legroom for a small flight. There was in flight entertainment even though it is a short duration. We waited on one passenger to board for a long time after everyone else was on.

Domestic flight, 1hr 20mins from SFO to LAX, which takes about probably 40-30mins on air.

Easy if you are a United States Citizen, when you go to US Border & Customs, bring your Passport if you arrive Internationally. Remember to pick up your check baggage before moving into domestic flights, as they will check the tag for the plane you are boarding in. (They will check your baggage again). Bring your ID/DL (Real-ID COMPLIANT) with you to pass security/TSA, passport works too. SFO is pretty strict as well as LAX. Domestic flight, 1hr 20mins from SFO to LAX, which takes about probably 40-30mins on air.

At Fukuoka, check in counter stuff was no experience , took long time and took out our preserved sheets to change to emergency exit seats without asking. The flight was late and we missed the flight to go back to SF. My luggage was broken. I had a terrible experience.

Chair was broken. Crew was awesome. Food was eh. Dinner food not so good the sandwich was good ( for airplane food) headphones hurt my ears. It’s hard because no one has plug in earphones

Republic was fine but Air Canada was terrible in the airport. They issues me a boarding pass that I placed in my wallet and then when I showed up at the airport they had taken the bar code away from the ticket because they changed the flight number even though the flight stayed the same time. This caused me to be unable to go through security and I had to go to Air Canada for help and they were horrible and almost caused me to miss my flight. Luckily I managed to get it figured out on my own phone, not the kiosks, or the agent I asked for help or the long line I was standing in!!

Flight was fine. Arrived on time. More room in the seats would be nice, but not something that is likely to happen.

Unfortunately your planes need maintenance. I am surprised your bathroom in business class was not working in 8 hour flight. Coffee machine was broken. Seat adjustment panel was bad. I will stay away from Air Canada in future travel.

The people are great! The trip to Japan is simply never ending!!! Not the problem of the airlines, though.

We were forced to check in our carryon and were given a green label that said to pick it up when exiting the airplane. We were told by the flight attendant to pick it up at the carrousel instead. We spent more than 40 minutes looking for the carryon which appeared at the wrong carrousel. There was no agent at the united desk for help. There was no entertainment.

Confusing with Air Canada and United flight, it was a hell, no help, rude people there, stressful environment

People were very nice and helpful. But the plane is noisy, and crowded. Seats are too small. Plane was too cold too. Air Canada app is very slow. Couldn't upgrade seats to the next section. Also surprised that basic economy seats were actually standby.

People were very nice and helpful. But the plane is noisy, and crowded. Seats are too small. Plane was too cold too.

Great crew and the plane was very nice! The problem was that we didn’t have WiFi on both of my flights. I found that to be very disappointing today when all the other airlines always have WiFi so I could work or watch a movie.

It was my first time booking from kayak and first time with Air Canada and I must say it was cheep and flight and experience was so good. My favorite KAYAK now🥰
