Last 2 weeks of the year are always expensive, Christmas/ New Years trips
Same every year from Dec 15th on until 3rd or 4th of Jan not really a surprise.
I went looking for a trip to any where south it was $1.5K and up per person.
I had to fly my wife home due to a family death one year at Christmas, ( not fun ) 15 years ago, bereavement discount +$800 YEG to YWG.
