Other North & South America Frequent Flyer Programs - Is PD making a run on AC for the YOW-YHZ corridor?

Trying to book a flight from YOW to YHZ with a hop in YYZ on both directions to hit the last 4 segments I need to gain E status and PD is $280 cheaper with direct flights...which makes me angry since it blows the fare rules on my travel sight and won't let me book it!! This is the first time I have even seen PD show up in the results this year with a reasonable fare, anyone else notice this trend on this route?

Porter is making a run on AC with every route they fly.

You might be able to get the fare even lower using a Porter discount code. There are some active ones in the PORTER DISCOUNT CODES thread, found where your thread was moved to: Other North & South America Frequent Flyer Programs
