It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

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

I just wrote a text which was supposed to be for the flight from Denver to spokane not Frankfurt to Denver.

The crew was doing their best on an old plane needing updating. Chairs that creaked and wouldn’t stay in position. My tray table was unusable as was on-board entertainment due the audio needing usb earphones (that were not provided). Prior to boarding in Toronto and despite being scheduled for a wheelchair and assistance, we were dropped off by clubcar without a wheelchair which I found myself by a gate. Due to no boarding gate assigned at that time we waited and when it was, it subsequently was moved from 64 to 95. No help could be found so I pushed my husband’s chair to that furthest gate in the airport at the highest speed possible for a 73 year old. And by that I mean I ran. It was a very stressful experience.

Wifi wasn't working on one of the UA flights after boarding.

Leg room was lacking. Legs crammed into seat in front.

T hey did a great job. Flight was on time .

the plane was old. the wifi didn’t work. the entertainment was boring and dated. the charging ports were impossible to find. i was mostly ignored by flight attendants that had no problem speaking to the man beside me. i got two drinks the entire time i was on the plane.

Crew was not very helpful. They forgot to serve me coffee and had to wait for a long time.It looked as if they were not very happy with what they were doing.

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

Flight was delayed, I had to put my luggage all the way in the back! They served only a beverage no snack on the way in Air Canada, definitely not a good first impression.

As is pretty much the norm with Air Canada now, we left late from the gate (45 minutes late). This is my 12th flight with AC in the last 12 months and 10 of those flights were either late or cancelled. AC essentially has a monopoly in Canada so they have carte blanche to charge exorbitant rates now and give poor service, with no repercussions.

Flight delayed. Thus connection to Paris missed. About 50 people were left alone in YUL for 22 hours. Extra fees involved. No back up from Air Canada. Then the next day issues with luggage (fee paid to Air Canada but flight transfered/ slided onto Air France) .

When we got to the airport for our flight from Chicago to Montreal which was scheduled for 2.00 p.m. they had no record of it and booked us on a flight at 3.30 very disappointing . We also had to pay 50.00 each for a seat. All things considered ,I will never book thru Kayak again. Next time I will only book directly thru Air Canada no second party booking Sue

Air Canada are just not reliable …. Kept cancelling /delaying flights

They did not have any meal options left on the menu. Only snacks.

My flight has been canceled and I had to cancel entire trip.

very disappointing there's no food service on an almost 7 hour long flight

Poor communication, when they chose to change my airlines to Alaska when entering back in the US. Even gate agents were confused.

No food for a 6 hours flight! Plus very expensive to buy ! Sit uncomfortable! Awful!!!
