Flight was really good, with no middle section on an A321neo for an international flight, from Ottawa directly to London. Staff was friendly. The food was okay, and entertainment amenities could be better.

Flight was really good, with no middle section on an A321neo for an international flight, from Ottawa directly to London. Staff was friendly. The food was okay, and entertainment amenities could be better.

The flight was terrible based off the temperature in the plane and the air smelled so stale and gross. I have never wanted to hosed lore in my life after I got off. The food was disgusting and seemingly low quality. The staff was friendly. The bathrooms were so gross after a couple of hours. I will definitely never book with them again.

The crew was great. There was no entertainment and the internet wasn't working. We sat in the run way for a LONG time which is always so upsetting. The seats are very close together and the flights are completely full which makes for a tough flight. Flying is just an uncomfortable experience.

Very kind crew. Vegetarian food better than usual. Prompt take off. Entertainment worked well. Could always do with more room!

The dinner was bland and boring, but the economy seats were surprisingly comfortable. The flight was very packed.

Great crew and entertaining Captain. Seats were not what we had expected based on my booking but things worked out in the end. Of course, like all airlines these days not enough leg or elbow room.

The entertainment system was down; food by purchase only; several people did not receive their luggage. No one answers at the local office or online about the luggage.

This has been the worst experience I’ve ever had. Basically, I lost my round-trip tickets because one of my last names was missing, and you didn’t allow me to correct it. I had to purchase a full ticket again. Once I get home, I will start legal proceedings against you.

It’s ok just the boarding point is far too far

They are a sister company with Air Transat and the two companies do not work well together. If you have any issues the two companies will blame each other and you will miss your flights. The help line does not help

Not great. Missed my connection flight, due to AC issue. We were sitting on the tarmac for 90 mins before taking off.

Flight was delayed and rescheduled 3 times before being cancelled. Flight was also delayed on our flight in at Moncton airport on August 10th. Never flying with PAL again.

Air Canada was fine but air Canada rouge and air Canada express was terrible with luggage delays. First flight was cancelled so my luggage did not make it to my destination with me. The second flight returning not sure why but my luggage did not make it on my connecting flight. Overall terrible with handling luggage.

The flight was good. My luggage didn’t land with me when I arrived in Columbus. So grateful I was able to get my luggage back within the 2 hours😍👍.

It was out first time flying Air Canada and it was ok, comfort-wise. I hope airlines are able to get a quiet room installed for young children flying. Screaming and crying the whole time in business class is quite unfortunate. That was the only thing that really messed up the experience.

Staff were very friendly. Plane left on time and arrived on time.

Air traffic delay meant boarding started, then plane was evacuated and passengers sent back to the terminal for 1 hour. Very little information shared.

The crew was amazing! I was a bit surprised and disappointed that there was not wifi available for personal use. The only thing I would change would be the seat cushions. They are not comfortable at all for long flights.

It was a very small plane and was ok. No food or entertainment so there should be an option for NA.

We were happy with the service and cost of checking a bag
