Going to book up a flight for June next week. Will let you know how I get along on the wait list regards.
So just to confirm what you guys have said
I should book entirely with miles, confirm one F seat and ask them to waitlist the second F seat. They should charge me for the one ticket now and the other will be charged when its confirmed?
If the waitlist doesn't clear then I will just have to make the other half sit in the back
