Don't have enough reward miles? Not to worry, the cost to purchase additional reward miles is only 30 cents plus GST per reward miles. If you have just half of the required reward miles for your flight, you can purchase the remainder.
The math on that from Charlottetown to Vancouver during the low season and assuming you have the BMO Gold mastercard.
- 1400 points * 30 cents * 7% GST = $449.40
- Regular Fair $289 * 2 = $578
Then you add the $148.90 of taxes and fees and it seems the air miles ticket costs $598.30 as opposed to $726.90.
