Tax refund on flight ticket

[Wai Hong Wong]

can I tax deduce the flight ticket which I exchange by miles rather than paid directly ?

if yes, how can I determine the cost of the flight ? thanks

 No, you cannot. Your miles were not taxable when you earned then and are not deductible when you use them. You basically don't have any basis on the miles to deduct.
