How to book airfare with FF miles one way and not get killed on flight cost the other way?
I'm looking to book flights for a trip in 2023 (most likely on United). Right now, the round trip airfare for cash is about $4500 (biz). I have enough points to book one way with FF miles. However, if I book two one-way tickets, the cash price for the one-way ticket jumps to about $5K. I see no way to book a ticket online with FF miles one way and cash the other way. Can they do that if I call the 800 number? Any other options?
