More about the bonus rewards?

The rewards that are being given out are “random” and how much of a discount you get, depends on the luck of the draw.

Simply log in to your account and see what your offer is.

While purchasing miles is not usually a money saving option, it can be a great way to top up your account for a trip you may be planning on taking, especially if you get the 50% offer.
