They advertise on their chart a flight from Minneapolis to Orlando in March would use 17,500 miles from March 26th – April 9th but when you enter the dates it populates 27,500 miles. The attendant says it is due to the dates being a WEEKEND. Spirit Mastercard cardholders who spend $10,000 or more on this card annually will earn a 5,000 Anniversary Bonus Free Spirit Miles.
