Thunderbird Airlines has a very successful Frequent Flyer Program (FFP). Each year 10% of the value of tickets sold are put forward to the FFP for future use by passengers. Customers can redeem these earned miles for future flights. In 2021, the airline recognized sales of USD2.1bn. Of this USD300m in ticket sales was from tickets that used miles previously earned that were redeemed in 2021 for travel.
