Long time lurker here and calling for help from the community. I am doing an academic survey as a final year student at Buckinghamshire New University, United Kingdom, to fulfill degree requirements in Air Transport.
The survey is about choosing FFPs and is aimed toward those who fly American or are members of AAdvantage. This will only take 6 minutes of your time and the survey will be closed in a month (i.e. 21 April) with results posted a week after.

Also, for discussion, what propelled you towards choosing a particular FFP? Personally I chose SK Eurobonus because of ease of making Star Gold. I know that some in Europe chose A3 for the same reason.
