We had a great flight yesterday YYZ-FLL with Porter.
The flight was delayed an hour from departing but they did a good job keeping us informed of the situation.
I had Porter Reserve seats ( front section of the plane, more leg room, very nice meal with different options, snacks, and generous beverage top ups, speedy wifi, friendly crew). It was a full plane and carry on baggage/storage didn’t seem to be the usual gong show for passengers like other carriers).
I had similar positive experience when I flew YYZ-Vancouver this spring.
