check in for premium economy very nice. Friendly attendants. Best security video ever. Seriously. That's about it. Not a good bang for the premium economy buck, to be truthful. I had hoped/expected for a little more.

check in for premium economy very nice. Friendly attendants. Best security video ever. Seriously. That's about it. Not a good bang for the premium economy buck, to be truthful. I had hoped/expected for a little more.

Delayed 2 and a half hours Middle seat next to a majorly overweight guy who took up most of my seat

Smooth ride but I wish they have better food selections.

Aircraft is designed with all 3 washrooms at the back of the plane, meaning that when there is service underway, there are no washrooms available and it gets very crowded at the back of the plane.

Multiple delays and gate changes resulting in arrival with a 5 hour delay.

One crew member, Brandy was very helpful with recovering phone lost in customs. The plane was ancient and poorly maintained. Checked baggage did not arrive with flight. Almost missed flight because if insanely short layover time. Air Canada is worst flight I have ever booked with Kayak. Wanted to charge for headsets for on flight media.

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😍👍.

gave me complimentary food as the flight was not full and was attentive to my needs

It was a nice and smooth trip. Gave a friendly environment throughout the journey.

Meal and drink service was good. Old plane with old business class seats were quite disappointing
