Looking to book two seats in J for a flight where one seat is available, the other waitlisted. I know this is the nature of the game, but I'm really unsettled about transferring nearly miles into my account with the uncertainty that I'll snag both seats. I am about a week and a half out from the two week notification mark. Anyone have a data point as to how many actually miles I'll need to have in my account to book/waitlist two seats? This will irreversibly wipe out all of my MR points, which is why I am dragging on pulling the trigger.
