As I answered in a previous thread (which this will likely be merged), I would hold off a couple more weeks until the Mile Plus program changes are announced.
Until then, you (or I) do not have enough facts to base a decision on. I’m committed to a 13K mile run this Saturday. Purchased the tickets many months ago and have other reasons I must do the flight. If I was put in the same situation today, I would not make a move until the end of the month.
