I recently flew with Porter Airlines on Flight PD372 on October 30th, and unfortunately, had a very disappointing experience. At the gate, one of their attendants gave me two boarding passes. I assumed these were for my itinerary from Vancouver to Montreal and back, but one of the boarding passes unexpectedly included a connecting flight to Toronto, which was never part of my booking or invoice. As a result of this error, my checked baggage was mistakenly routed to Toronto. When I contacted Porter’s customer service, I spoke to an agent who apologized on behalf of the attendant (employee number 13209961) and promised to have my luggage flown back to Montreal. However, shortly after, I was told there was nothing they could do except for me to travel to Toronto myself to pick up my bag. This is highly unreasonable and unfair, considering the issue was caused by their staff printing the wrong boarding pass. This entire situation caused me significant inconvenience and stress. I expected Porter to correct the mistake and deliver my luggage as originally planned, but instead, I was left with the burden of fixing an error that was not mine. I even have a photo of the staff badge of the employee who made the promise, yet the company still failed to honor it. I hope Porter Airlines reviews their internal communication and baggage handling procedures to prevent this from happening to other passengers. Customer care and responsibility fell short in this experience, and I am still waiting for a satisfactory resolution.
