Would have been nice for me yesterday. I was able to book a standard award from HOU - LAS at a great time and a standard award back to HOU at a terrible time. I really wanted an early direct home so I waited until the night before the flight and still only Freedom Awards were left for the good flight so I thought I would do a Freedom upgrade until I found out it had to be a round trip. I ended up having to take the worst flight instead of being able to use a half Freedom Award. I hope they consider changing this soon.
