My million mile bonus was posted this week! This should ease some concerns about LatinPass making good on their offer (it'll also probably prompt a few to start calling LatinPass ten times per day instead of five to ask about their status).
It took about 12 weeks for the bonus to post after my last transaction. At least one of my hotel stays didn't go through properly automatically, but LatinPass notified them and sorted this out.
Keep the trip reports coming; they're great. Only 23 days left...
