Per deal_with_singh of RedFlagDeals, Flight Network, a large online travel agency, is offering a coupon for $CAD 15 off any flight, including one-way tickets. This can be a decent discount off short-haul travel, like between Toronto and Montreal.
After searching for a flight on Flight Network and selecting your preferred itinerary, enter in the “Promo Code” field “KCC15” This will discount $CAD 15 from your ticket.
Flight Network generally has the best-available rates for flights. On a round-trip ticket between Toronto and Ottawa, booked as two one-ways with the coupon, you save $30, or about 14% of the normal ticket cost. It’s uncommon to get that kind of discount on a low-fare ticket.
