I've got about 900.00 (3x300) in bump vouchers that I'd like to use for some trips. One of the trips is about 465.00 (PD cert, Europe, non-direct routing). I don't wish to send in my vouchers to pay for it because of the routing so I will be forced to use the airport to purchase/ticket the itinerary. If I use 600.00 in vouchers, will they issue a refund of the other 135.00 in voucher form immediately, or do I have to wait for it to be processed? If I have to wait for it to be processed, I would prefer to use the 300.00 voucher + 165 cash to pay for the ticket. Can travel agents process vouchers if I am using a PD certificate?

Thanks...
