I had been searching for revenue tix ORD-YYC. I switched to searching ORD-PSA, first revenue, then award.
The revenue chart came up find for ORD-PSA, but then I clicked the "Book SkyMiles Award Ticket" button and got this.
Note that at the top right of the screen capture it does say
"Chicago-Ohare, IL (ORD) to Pisa, Italy (PSA)" but it's displaying flights ORD-YYC. (of course, if you want to give me "First" class tix to PSA for 80,000 r/t I'll take them!)
This happened on several different occasions today. WinXP, Firefox 3.6.3
