Air Canada

I had the worst experience with air canada for my son! . The flight Ac 7631 was canceled but they emailed that when we arrived in the airport and waited to get help for 3hrs and finally when we are waiting to get help from air line staff, she said that available ticket is only 2days later on 2nd July. My son went to Canada with other airline on that day with expensive price ticket. The worst thing is when he checked in in the airport to return to home he heard original returning back home ticket also canceled. That is ridiculous ever !
He came home to buy another ticket with evpensive price ticket! They Never apology that situation and resolve that!
I never forget this horrible experience with air canada and I would never recommend to get air canada from now on!
