I am the primary platinum card holder. P2 needs to buy a last minute single TPAC business class ticket. I made P2 an AU, but her card has not arrived yet. Will there be any issues buying the fare with my card on her behalf or do we need to wait for her card to physically arrive to make the purchase? The issue for us is that we are currently traveling and won't be able to get home to physically get her card and would prefer to get the ticket now if possible. Any thoughts are welcome and appreciated!
