has anyone booked travel with there scotia bank amex pts , why i ask is im going to rent a car with ac vactions ,its $100 cheaper than anywhere else i looked , so i phoned scotia rewards , and told them where i want to book a car with and want to pay with pts after i pay for car with my card, guy tells me it could be a couple of billing cycles before all my pts are used to pay for this charge, doesnt make sense to me, if i have enough pts , why dont they just take the pts all at once.
