The agent at check in was very cordial and gave me seat 4a with nobody beside me as I asked if possible

Seats not as comfortable but understand as it was a smaller plane/ short flight. All in all, I’ve never had any issues with Porter. Great company to fly with

3.5 hr delay for a 1 hr work flight. No information as to why the delay until 20 mins before boarding.

There was a 5 hour delay. Missed connection and now an almost 21 hour lay over!

The flight was fine see earlier note for the problem

The staff is always great. Just the fact that our flight was the only one delayed from Halifax when all other carries were still flying. It happen a year ago out of Toronto as well. All others were flying but our flight got cancelled 1 hr before the time of departure.

Porter was excellent. Boarding was a breeze. The seats were a little uncomfortably but the overall trip was excellent.

Chaotic boarding, but mostly my issues are with Toronto airport

Tight transfer in Montreal. (15 min) However, we made it, as did my luggage.

travelling in 14th of April and now we are in 17th , I have not received my lost/delayed bag... this is very bad and the worst part is their call center is not able to see where is it!!!!

I bought a ticket from Kayak. When I got to the airport, the was no ticket. I had to pay 5X to get to my destination. No response received from Kayak. I will NEVER use them again.

I had a good experience. I liked being informed about the status of my luggage

We boarded 1.5 hours late. Long wait for the bags when we got to Mexico City. Long wait to get on plane with people mover truck. Friendly staff. They answered all questions as best the could. Such a long, long walk from the plane to customs. Thank you, Michael A. Burris Cambridge, Massachusetts USA

I was forced to check my carry-on bag, which I don't appreciate.

Terrible. Air Canada decided to wait for another flight. Due to the waiting, the weather got worse and connedting flight got cancelled. Air Canada said it was all due to the weather and didn’t pay me for the hotel. Not speaking of 3 hours waiting for my luggage. Never again!

Even though the flight was an hour and a half late ( unforeseen maintenance problems) every was great.

Delayed leaving. On arrival we were taken to the airstrip and had to get off onto an over crowed bus, not all that passengers fit. Drove around the airport for 20 + minutes. Taken off the bus told to go upstairs 3 flights then all the passengers had to walk a mile or more , those of us old there was no one to direct us to were to go. I asked several people with no answers. Once I got to baggage claim my bags were not on the right bag claim. Once again asked for help and finally someone found my bags on a different carasel. Very frustrating.

It was delayed but got us to YYZ. I had great copassengers.

It was upsetting that the flights were canceled but that was due to weather. I did not receive any vouchers for food or a hotel stay when I was forced to spend the night in Montreal. I was also upset when my seat was changed many times.. The plane seemed old with a non-functioning screen and loose side pockets.. All in all in need of updating. On the positive side, the staff in areas was friendly and helpful.

AC announced early departure, but departure was delayed about 1 hour due to engine problems.
