How far out is generally the sweet spot for either Westjet or AirCanada (and I guess AirTransat) for flights in July? I looked at some flights when the seats were first available several weeks ago and they're up about 10% now. In 2022 I booked around late January for early July flights, but I hadn't been watching prices up to that point so I don't know if those prices were better than they were a few months earlier.
