We need to head up to Montreal to visit McGill. College visit.

It seems that regardless of when I look the fares ex NYC to Montreal for a weekend consistently price out at about $375+ per tkt. The recent AC promo, tango class only and Porter discount (with a long layover in Toronto), don't much bring this down or just aren't available. Does this route ever have fare sales? And, if not, its also something we would want to take into account in terms of DD coming home from school for the weekends. Flts from NYC to other college towns, even farther than Montreal, are often much less if booked in advance. Thanks.
