Both my wife had reservations for the above named flight on Aug 30, 2021. On the boarding pass it states the gate closes at 08:45. Due to back up in security we arrived at the gate at 08:47(I checked the time.) There was no one agent at the gate. Contract employees who deliver wheel chair passengers finally made contact and an agent appeared at 9:10. The flight had pushed back and we were advised that there was nothing the Airline could do. I requested to reroute our tickets through Calgary to back track to Regina AND WAS advised that my tickets were not negotiable or transferable and that I was out of luck. I then asked to status of our checked baggage and this agent advised us that the luggage was on board the flight. That didn't sit well and I sought out WestJet Baggage and found our bags were not on the flight. I suggest that this crew was anxious to get out of YYZ and closed the gate early. To get home to Regina I had to purchase last minute tickets with Air Canada at a cost of 2, 000.00. I believe Westjet should be held accountable and refund the cost of the Air Canada flight at 2, 000.00 and issued a formal apology.
