For the info of anyone still shopping for a trip:
canadatravels.com issued a “discount coupon” good until Feb. 28th which gives instant discounts on their prices. Just enter coupon number PCDN2009 on the pricing page in the “redeem a coupon” box and hit requote.
Sunwing has advertised a “no fuel surcharge” discount until Feb. 28th reducing their taxes by about $100.00 per person.
I did a sample booking for a sunwing flight through canadatravels.com and you end up with both discounts on regular bookings.
