On another note, I've bought a few vouchers now, and have had a few underway to buy flights for next year, and so have had to wait each time for the new voucher to be re-issued etc. etc. slowly reducing the value on each voucher one at a time. I just got a re-issued voucher, and they have combined the remaining value from 3 different vouchers I had underway to give me a total of $591. Overall, I guess it's fine, though it's a bit of a pain as I now have to wait each time for the voucher to be re-issued if I want to buy numerous flights in succession. I would've preferred the three individual vouchers each with their remaining value. Much more flexible.
The operator indicated that they are having to manually re-issue/create the gift vouchers with the remaining value, so I suspect they've combined them to save the some hassle for themselves. I guess I'll just have to start using some of the other 20 vouchers I have bought. :shock:
