Originating from Colorado Springs Flying to Nice, France and then back from Copenhagen in February...

I can take the A340 from LAX, 747-8 from Boston or United 767/777/787. I could also take the nonstop from Denver to MUC or FRA.

I should be flying quite a bit next year and would think I would hit Platinum. Currently at *G this year.

Do I take the shortest (time) flight or do I pick the biggest PQM miles flight such as going through IAH or LAX?

Any tips?
