I love that Porter planes depart from downtown Toronto, and you can get there 30 minutes before departure. It's only a 1 hour flight to Montreal, and door to door, I can get from my house to my destination in 3 hours, versus 6 hours by plane or car. Nevertheless, I've had my last two flights cancelled with Porter. This has been a huge inconvenience, and it seems to happen quite often. If they got their act together, and had flights leave on time and not be cancelled, I would fly with them much more often. There is the potential to be great Porter, if only you were more reliable.
