Air France is an airline that offers flights, including a flight from an unspecified location to Paris on February 9, 2019 [2] [5]. The airline has a frequent flyer program called Flying Blue, which allows members to earn and redeem points for upgrades and other rewards [1] [3] [4] [6]. To upgrade to business class using points, a Flying Blue account must be linked to an American Express card [3]. The cost of a business class ticket on Air France can be partially paid with points, with the remaining balance paid in cash, such as $10,136.73 for a business class fare [4]. Air France tickets can be purchased and upgraded using American Express points, but upgrades to first class are subject to availability and require a large number of points, such as 1,412,253 points [4] [6]. Air France sends emails to customers with information about their flights, including check-in deadlines and baggage restrictions [2] [5].
