I'be just gone through pages 17-22 -odd of this thread where so many people were having problems with Qantas web site crashing etc etc, not being able to book, angst, frustration ...
Gift vouchers excepted, why on earth wouldn't you use a travel agent? So much time, angst, and perhaps, failure, vs a simple e-mail or call saying 'please do this' - and its sorted.
The TA I dealt with for 10 years (I now have another) charged no fees etc and even if they did charge, say, $30 or something, how does that compare with hours of your time, sweat and maybe not getting the booking you want?
I never asked, but I think that TA would have booked a GV for me as well.
