Porter is offering flights from $39 for Cyber Monday for EWR-YTZ, promo code 3G3WFG
flyporter.comJan 7 and may more dates
Found on that day for $41 including tax for one way. Hard to search for all dates cuz they don't have a fare calendar. And matrix won't help here cuz not all of the fares are discounted under this code, only a few from the day.
