Not when you canceled. The nonrefundable ticket's value is stored under its ticket number. Next time when you rebook, $150 fee is deducted from the credit first, then if the rebooked ticket has a fare less than the residual value (after the $150 fee), you get a new voucher with a new date for the difference.



The expiration date of the original voucher becomes irrelevant once the voucher is used.

However the flight must be canceled BEFORE departure (dont know the cut off of the "hours"), else the ticket has NO residual value.



It becomes part of the nonrefundable ticket value which is subject to the $150 fee.

Why would you book a non-refundable?
