I have seen the cheapest flights fluctuate from $1,350 to well over $2,000 during the past two months. Unfortunately, when the prices were at their lowest the summer had just started so I didn't have the money in the bank to purchase the tickets.
With the help of a little forecasting in prices, and a decent amount of money now in the bank, I was able to finally purchase my tickets towards the end of this week.
The final price for return airfare to Mumbai from Saskatoon, taxes and fees included, $1470.
