I did purchase the trip - well, an altered version of the original trip with a bit more finesse, I met a former student for coffee who told me about his recent whirlwind trip through Europe - pretty much all of it. He strongly encouraged me to add Prague to my itinerary, which I was able to do since I hadn't finalized with the airline. Splitting the trip equally between Paris and Prague adds more interest, to me. And, since I'm allowed one stop over in the itinerary, adding Paris as a stop over cost no extra miles for this trip. I'm fortunate that Air France is the partner carrier with my airline. The natural route is Los Angeles - Paris - Prague - Paris - Los Angeles. The only add on was additional taxes of about $54. What's the lesson now? Perhaps there's not a simple take away. I'm glad that I acted. I'm also glad that I waited long enough to be able to have a creative option that is more satisfying and interesting than my original plan. .
