Wow did porter just increase their prices recently? Flights are $150+ more expensive WITH PROMO CODE than I've ever seen before

I fly often Toronto to Thunder Bay or Ottawa to Thunder Bay for example. even with the current 20% off, my flights are now more than $150 than they were usually, what gives? Like now Ottawa to Thunder Bay for example is nearly $1000, SERIOUSLY nearly $1000 for a 2 hour flight??? this is f&cking insane? What in the h3ll is going on?
