Qantas have a short, sharp, special offer for a 15% bonus on transfers made from credit or charge cards to your Qantas Frequent Flyer account. The downside is that this offer does not apply to cards that have a direct sweep into Qantas – they have to be transfers you can initiate from your rewards account.
The downside to this offer, is that there are not many cards where you can hold points in a reward account and transfer at your leisure. Most cards are direct sweep.
Outside some corporate accounts, the main consumer card that allows this is the American Express Platinum charge card.
The offer is open for transfers made by 15 November, 2013.
