Spirit Airlines is well recognised for its unbelievably low costs.

They achieve this by giving the passenger the option of purchasing any additional services being offered on the flight; this cost is separate and apart from the airfare.

In addition to its already low airfare Spirit Airlines is still able to offer new holders of the Free Spirit Onyx MasterCard the benefit of earning 15000 free Bonus miles with their first purchase.

15000 Bonus miles is a lot, think about it that is three times round the globe! These trips will be granted by Spirit Airlines in off peak seasons only, but the deal still remains great.

This is yet another reason to travel again and again with Spirit Airlines.
