This was my second leg of my trip and was delayed so was worried about my connection in Montreal. Still hungry so on boarding I asked a flight attendant if I could use my $14.00 voucher on the plane for food as I was starving. She said she would check and let me know but she never came back. So no food again as none was offered. Had to get my bags and check them again and that was ok but don’t understand why I had to go through security and because of them almost missed my flight. No food offered nor possibility to purchase food so still hungry and just watched a movie and hoped I could get food when I landed. Was able to use the $14.00 voucher to buy something and had my family bring food as I was now starving. I’ve been travelling on AC for years and this was my worst experience ever. After our flight got cancelled in SXM and was told the staff there didn’t work for AC so couldn’t do much to help us was not a good experience

Staff looked unprofessional. Sloppy uniforms and hardly a smile to be found

After 3 hours of delays, they ended up cancelling my flight. And although I could purchase one-way tickets to get to my destination, they would not offer me these flights as compensation for the cancelled flight, and I didn't end up making it home until 13 hours after I was originally supposed to arrive. It made for an extremely strenuous end to an otherwise good trip.

Be careful about the bad policy and when purchasing seats

Very disappointed with premier lounge. Food selection very poor, both coffee machines out of order. For the price you charge for an upgrade, the seats don’t fully recline, movie selection is old. Not very good value. Asian airlines are light years ahead at a more affordable price.

Flight late with no explanation why so late boarding. More than made up the time in flight. Woman in seat behind me would not allow me to recline my seat so could not sleep. Slow to clean up after meal so has to leave my tray down. Flight attendants average at best. Premium economy experience was poor. It was a special trip for us, a 70th birthday. We could only book seats that were apart and no efforts could be made to get us together. Just poor all around

Business Class was great with two exceptions: they should board Business Class Only first, then loyalty, then handicapped and families with young children then by zone. With all the loyalty and credit card holders and families with kids, dozens boarded before us and we were in row 3. My only other compliant with Air Canada is they don’t serve drinks and snacks in business class until at a cruising altitude. Transat and Emirates serve prior to takeoff which is especially nice during boarding of big planes and de-icing.

The only good part was what we paid for, we travelled premium economy, good comfort travelling with a baby. Flight with AirCanada was again delayed for more than 4 hours, service level is horrible and they don't care. They deliver the bare minimum for a world class price. If you can avoid canadian air lines, do so, oligopoly does not help them to strive for any service level.

We left over 2 hours late and they didn't even give us a complimentary snack, when getting to the desk I asked if I could be put in a row with only 1 other person or an empt y one I was told the flight was full when the last two rows were empty. All around over it

Again, we were rerouted all the way to Zurich and had a longer journey than expected.
