I have a related question if anyone could help . I have a friend who miles are expiring at march 2019 . I have tried looking for donations to extent the miles and there is none,. Then I tried to redeem for a shopping voucher and was told that was an option for overseas residences. So I finally ended up get a AVIS one day car rental voucher and now got a reply again with the same answer needs too be a Thai residences, so I have ran out of options.
Any suggestions ?
