1. GS -> 1K
2. 2013 1K -> 2014 GS -> 1K
3. 2014 GS to 2015 1K (don't understand how this is different from question 2)
4. The reason I didn't re-earn GS was that I didn't do nearly as much international travel. Corporate policy allows BusinessFirst for international travel but not many international trips this year. UA has been great for my international trips. I just need to do more international projects and will likely do several trips this year.
5. Again, we were lucky not to have any situations occur in Asia this year. Also, during the past year, my wife and I earned a lot of miles. When we took trips together, I usually purchased the ticket with miles while she used the cash (so she got the miles).
