New discount transatlantic European airline: Primera

I just stumbled across this while I was browsing Google Flights, as you do. It looks like there's another no-frills low-cost carrier from Europe that will fly between Europe and the US/Canada for crazy low one-way prices.
Their website lists as low as $99 one way, but most dates are $159 one way, which is still a great price, and it's nice that the one-way tickets give you the flexibility to travel while in Europe. You can click on "see year calendar" to see the cheapest time to fly! (Spoiler alert: the cheapest time appears to be September/October. You can fly to Birmingham from New York for as low as $119 as soon as May, but after living there for a while I don't know why you would want to??? JK it's not that bad but like it's not London, is it?) 

Fly from Toronto, New York, or Boston to Paris, London, or Birmingham, starting this spring. It looks like the prices are some kind of a sale, so I'd snatch up those tickets while you can. Go check it out!
