dont do it
hi,
you can do this.
i had to cancel tickets, but its a pain in the ... to get the money back (takes a couple of weeks) you dont know which part has been credited back, if you have problems you are doomed with lifemiles.
i had 4 tickets, which have been cancalled, it took me 3 days to cancel the tickets, as the PIN computer didnt get my CCV Numbers etc.
the agent didnt know how to cancel the ticket first, and i had to call back a couple of times.
i can not recommend doing this, its not worth your while trying this. wait for the next 2/1 promo and buy the miles for 15cent. still a bargain!
