1) 1k
2) Don't see the point in trying for any status on United anymore. Thinking about trying for an EXP challenge. I'm actually expecting a big increase in international travel (esp. TPAC) this year, and I might do some of it on UA if I can confirm GPUs at booking. Otherwise, it'll be someone else. I suppose I might hit 1k unintentionally this way, but I'm certainly not going out of my way to do so.
3) Service reductions have made it very difficult for me to use UA to conduct business. I have fewer and fewer options that get me where I need to be when I need to be there. Even with a week's notice, I often can't find anything (and when I do it's a middle seat in E-). No upgrades so far in 2015. The fares are exorbitant (easily twice what I was paying 18 months ago) and the perks are nonexistent. PQD isn't an issue.
