I recently flew Finnair and was impressed by the structure of their frequently flyer program and how different it is from American (see below). The Finnair structure seems more fair than the more arbitrary points/segments structure of AAdvantage's 25/30, 50/60, 100/100. The average passenger creates more business for the airline flying 100 segments than earning 100,000 points. Thus it appears that Finnair rewards flyers based on the business they bring to the airline instead of aesthetics and symmetry(?).

Does this make sense or can someone help me understand the apparent irrationality in the current AAdvantage structure?

Thanks

Finnair Plus program:
Basic, Silver (40,000 tier points, or take 24 scheduled flights), Gold (90,000 tier points, or take 54 scheduled flights), and Platinum (150,000 tier points, or take 92 scheduled flights).
