Trying to book PDX, DFW(layover in DFW), RTB, PDX.
when I try to click through the DFW-RTB segment, it looks like it is processing and then just brings me back to the same screen, I click again and it won't go through.

Ironically, I can book the reservation with miles just fine, but not with $$.

I tried using Google Flights and then clicked through to book at AA.COM, and it gave an error and say try again..

Thoughts?
