I want to book RT award travel for me and my wife. I only have ~50K miles but the cheapest awards I can find for the dates we're interested in are 30K each--so we're 10K miles short.

Supposedly with my US Airways Mastercard, I can get a 5K discount per ticket. But when I try to book online, The 60K amount gets discounted to only 55K; leaving us 5K beneath what we need.

If I called, would it be any different? Sounds like it's a 5K discount per booking and not per award ticket.
