Should I request a refund for a small amount?
 

Ugg... I booked a flight with the Paypay promotion for my daughter and it went down $77.00. Should I pay the $50 to get a $75 credit? Not sure how long vouchers are good for.

When my fare went down, NW took the $50 off the voucher amount so I didn't pay cash. I received a credit for what in your case would be $27. Either do it now (why not get a $27 credit) or if you have a crystal ball and think it will go down further, wait until it goes down again to do it so you only pay one $50 fee.

ECV's are good for one year from the issue date. If the flight has a WP number assigned to it then you should be able to do this online. Login in with said account and go through the motions of changing the flight but select the same exact flights that you have booked. The system should give you the ECV minus the re-issue fee.
