When it comes to travel, timing is everything. So book now for Christmas.

Gone are the days when the best airfare deals for the holidays were 10 months out or at the last minute.

Global flight comparison website, cheapflights.ca, has developed a tool using its search engine data to pinpoint exactly when prices are at their lowest over the holidays.

For example, book the cheapest airfares to London, England, for Christmas in mid-August; if you're planning Delhi, Mumbai or Paris, book flights the week of Sept. 10 (that's about 15 weeks before Christmas) and for Bangkok the week of Sept. 17.
