I don’t feature that many external competitions on Head for Points. I do have a soft spot for the Business Traveller ones, however, because the prizes are usually very generous and your chances of winning are not bad.
This month, Qantas is giving away two Premium Economy tickets to Dubai. The flight times are not ideal (the outbound flight from London is overnight) but if I wasn’t paying for it I wouldn’t be complaining!
The link to enter is here and it should only take a few seconds.
Note that you must be UK resident (excluding Northern Ireland) to enter. The closing date is April 1st. There are some black-out dates for travel over Easter and in December but apart from that Qantas seems flexible.
