The only thing I can't give good or really good is the fact that we didn't have food ,just a packet of pretzels or cookies which is normal,and ofcourse there isn't any entertainment. I've always flowen WestJet ..I really like the airlines..this plane was smaller one ,pretty tight seating.

Again, flight was late. It’s expected of this airline now i guess.

Counter representative refused to check my luggage despite paying for it in advance

When I purchased the flights I included the luggage, the luggage was not added and got charged the full price anyway. Had to pay for the luggage at check in. Initial flight was delayed, we missed our 9am connection (flew with my wife), then the airline rebooks us to the next flights, putting my wife in at 1.40pm and me at 4pm, what a crazy wait time. We managed to fix it with customer service and they put me in the 1:40pm flight too, but they left my baggage behind in the 4pm flight. When arrived to my destination, of course no luggage. It was delivered to the address thankfully late at night. The experience sucked.

Did not like the seat selection which was poor.? My daughter and I never did get seats together because it all took place at the last minute and we had to accept whatever seats were left

I rated westjet poor on food for not accepting debit to make in flight purchases. This is dumb.

There is no snack and nit much that would be considered gluten free in yiur food selections. One of your snacks should be a gluten free cookie or small bar etc. maybe it was me but I didn’t see any free movies just internet connection and YouTube .

What do you expect from a Dash 8 plane? No seats really comfortable.

Delayed 8 hours, This is the 2nd time in a month that my flight was not on time.

my wife got very sick and we did not travel . we booked and bought the travel insurance and dot nothing but hassle and a triangle of stress in trying to make the insurance claim I called in and was told they would not give me anything in writing to say they would not refund my money back this make it impossible to file the claim I will never book with Kayak again.

My seat was one of those that couldn't recline, but the problem was that it was abnormally upright, so the headrest actually made the seat concave, which was uncomfortable and hard on my lower back. I had to ball my jacket up and use it as lumbar support. goodness I had it with me.

Boarding was so so after zone 3 was called all other zones went in

Good. But not to serve tea/coffee during a 8-hour plus flight is bad.

We had a long walk from one gate to the other. The busnessclass was full and we could not get seats together.

Too many delays. Seats too small. A budget airline. Will never fly Air Canada again.

On board wifi or other entertainment. Landlines option was good but ran late to Pearson

I liked a lot , the flight attendant so nice ,the seat very comfortable I enjoyed the flight , I will do it again with Air Canada,

I wish they gave the earphones earlier rather than when we are already in flight.

Very nice staff members are very nice and friendly helpful

We were a little late pushing back ,but arrived a head of time.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Missed flight. Requested assistance for my father and he did not receive it in Paris.

Business Class was very comfortable and the food and service was top notch.

The crew was very nice. The equipment on the 747 felt old.

As expected. Would have appreciated a 3-day headsup reminder as a reassurance that all is well.

Poor food on flight between Toronto and Stockholm Airport Toronto too crowded

The plane was late (as was my flight out from Birmingham the day before)

Business Class Configuration was excellent- private and comfortable. Crew and service were excellent. I really appreciate Air Canada cabin pressurization equal to an altitude of 8,000ft. Upon landing, I felt more alert and refreshed than typical for international flights

Hard to use tables and TV screens interfere with the enjoyment of flight experience. Other than that it was a smooth and comfortable ride and we were well taken care of.

Excellent flight overall. Lufthansa Business service was excellent with great cabin crew and very good food and wines. The seat comfort was excellent. Only a slight reduction in score due to the 747-400 being a relatively loud aircraft these days.
