Official T&C's of Avion says I can book a business class ticket - see below:
Redeem your points up to the allowable Maximum Ticket Price from the Avion Redemption Schedule and then redeem your points at 100 points = $1 CDN for the upgrade to business class value. As an example, Toronto - Vancouver, maximum ticket price is $750.00 any difference in the ticket price above this amount can be redeemed at a 1% value.

Does this mean that if the ticket is $1000 + $250 in taxes, that I can use 35k to get $750 max ticket value and then have to:

• a) Redeem 25000 for $250 remaining ticket price
• b) Redeem 50000 for $500 remaining ticket/taxes
• c) just pay the difference of $500 in cash

Appreciate your help on the interpretation
