1) '14 1k. '15 1k.
2) Didn't change. I considered abandoning UA when things were really bad but ultimately e+, sdc, and my huge bank of miles kept me sticky.
3) Did about 50k revenue miles on other metal in 14 due to UA's inability to maintain a schedule (which seems to be getting better). But made it without issue.
On pace to hit 1k in 16 without issue.
