Good but airlines getting smaller. I didn't like the meal but the service was fine. Flight was fine and luggage arrived. So good.

Given I (and I’m assuming most people) have both carry in and a personal item included in their fare, I find it very unfair that on neither of my flights I was able to use the overhead for my small backpack because they were completely rammed with luggage, people personal items, jackets, hats and other items. So the only item I brought in had to be stuffed under my seat while they had their leg room and sat comfortable with all of their items in the overhead. This has to stop because I was uncomfortable on both flights when I only had one smaller item that could not be checked due to its contents (medication etc). Plenty of people could have checked theirs but chose not to and then took up the space allotment for 2 people.

From pre boarding to flight attendant, crew and baggage handler, excellent. Didn’t lost my luggage like West jet.

The Sears in the 800s are not too good perfect Airbus why cant the new 737 fix that

The experience was great, the crew was very polite and hospitable. I will definitely make if my go to airlines.

Everything was good. Flight was on time, luggage pickup was quick. The staff were great. Could not ask for anything more.

-The cabin was ice cold - When we arrived in Houston there was no gate available -We had to wait 90 minutes for our luggage to arrive.. In the future I will avoid flying with Air Canada at at costs

We enjoyed that we boarded and took off on time. We didn’t like that our connection flight was a twenty minute walk through the airport with only one hour in between flights.

Two flights,both poor. No entertainment. Cramped and uncomfortable seats, little space, the rest was OK. Staff were acceptable good.

The flight I was connecting with waited for me even though my 1st flight was late. I really appreciated that.

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

The ground staff was so rude in Toronto airport ...very rude and did not answer simple questions, and made me look like a fool. Very rude ground staff.

As previously mentioned in last review , seats are small and uncomfortable, and baggage fees are high!

We got home a day late because of mechanical problems and that they wouldn’t put us on available other flights.

The seats have no leg room and my seat head rest was broken

Well organized check in and boarding. Aircraft had comfortable seats and lots of leg space, both ground staff and crew members were nice.

The flight was good they didn’t take off on schedule

It was a pleasant flight all around. The staff were courteous and it went by quickly. The pilot was great and the plane, well, I just couldn't do it without them. Blessed to arrive safely, thank you.

The connecting flight was delayed and though months in advance, airline changed the layover from 4 hours to 13+ hours. To go back to a 4 hour layover, we'd have to pay $1000+ extra PER PERSON.

Flight cancelled after 1 hour delay No explanation Auto Rebooked to a flight the next day
