I've been saving my United FF miles to use next Dec. to MCO. I'll be ready to book the award travel 330 days ahead of time. One of the posters on Flyer Talk said I may have difficulty getting seats in Dec. Anyone have any experiences with this? Does it make a difference that I'm flying Hawaii to MCO? I need 6 tickets...but 4 on one flight and 2 on another could work too. I'm just trying to figure out how many other alternate plans I may have to make to go on this vacation. How many seats per flight to these designate for FF award travel anyway?
