No worries, they will honor the ticket. I've heard it's less expensive too, but I want to make sure that she has simple flights with carriers that I trust as well as hubs that I know and trust, and to me, it's worth the (possible) extra cost.
The Philippines does have a departure fee that must be paid in the Philippine Peso (I would imagine this is covered in the CFO pre-departure course), and of course, she will want to have some money (preferably American currency) to have during her trip in case she wants to make a phone call, have a meal, etc.
I'm currently in northwest Missouri and was looking at flights on Travelocity and Expedia to Kansas City. You can get them for about $1200. The simplest option I saw would fly her straight to Cali (I think Los Angeles) via Philippine Airlines, then to Kansas City via Midwest Airlines. The only thing I didn't like about that path was it's a 13-hour layover in Los Angeles. My plan was to fly to L.A. the night before, surprise her at the airport upon her arrival, and take the same flight to K.C. Of course, I would contact Midwest and explain the situation so that her and I would be able to sit together

However, it's a cheaper and easier option for me to fly her to Minneapolis and drive up there. I think she'll enjoy seeing some of the Midwest's countryside
