Was not sure where to post this,sorry. OK, I am going to do the Philippine trip again and need advise. With the new well new for me, charges per flight, milage etc I want to make sure I book the most expensive route. I was told this way if I need to change say from detroit to LA instead then I would have enough paid to cover any change in fee. My buddy says he would get a refund for me if it was a less expensive route.

The route that will be booked as of now will be CZM to ATL to DTW to NGO to MNL. Wondering if there is another I should book instead?
