Thus, you don't exceed the MPM (at least checking the DTW routing outbound). However, it seems that you might have to find a partner that actually publishes a fare all the way from GOJ to PPT for which that routing would be valid. I'm not sure that you're going to be able to do that. KE does have a fare, but the problem is that you wouldn't get your JFK stopover then. You might try playing agent roulette a time or two to see if they'll ticket it since it does fall within the MPM, though.
