(1) If your status remained the same from 2014 to 2015 or changed on Feb, 1. 2015 (the status changeover date). (What is your status?)

2014 - Platinum
2015 - Silver, now Gold because of 1MM in late January. I never really had Silver.


(2) What were the reasons your status changed, or remained the same on Feb. 1 ?... please expound in some detail FOR THE MOST RELEVANT TOP REASONS FOR YOU......

Less flying overall, and far less PQD.

(3) Did you have any particular difficulties in maintaining or increasing your 2014 status for 2015?

Yes, because of a drop in overall travel. Also, even if I hit Gold with annual BIS miles, I'd have been a long way away due to low PQD. Since 1MM was within easy reach by Jan 2015, I'm not that concerned with achieving status any more. I don't see work travel getting me to Plat, 1K, (or 2MM), and Gold works well enough most times.
