WorldPerks member Con Jager discovered that the DIY award planning method sometimes has its faults. Recently, when trying to make a flight arrangement of the nwa.com Web site, he discovered something unusual in his request. Can you spot it?

Yes, the Web site booking for an airfare with an mileage upgrade from Anchorage, Alaska to Washington D.C. through Minneapolis was $1,325.80, plus 2,147,478,112 miles for the upgrade. Needless to say, his booking showed an “insufficient balance,” and the “Buy Miles?” icon was lit up. If Con had decided to buy the miles for this trip, NWA would have instantly been able to exit bankruptcy. And how was your day?
