Mooper,
Be sure to let us all know how this all turns out. I know I'm curious. Are the miles going to post in time? Will you and your wife receive the upgrades wanted for the most crucial segments of your trip? What will you do with your newfound lifetime PLAT status? The questions never end...
Really, I am curious. Perhaps, though, it's time you cash in some of those miles. I am assuming you have not used the 928,000 miles you have earned in the past year. Blowing a few of those on business/first seats might not be the worst way to assure yourself the best couch, especially now that you don't have to worry about your EQMs each year like many of us.
Good Luck!
