I was able to pull up my CHI-PDX-LAX-ELP trip (AGR 2-zone) but it shows the CHI-PDX portion under "Departure" and the PDX-LAX-ELP portion under "Return". This should be one continuous trip. I hope they don't try to say that the connection in PDX is not guaranteed. I know that this is not currently a "published route" but it was at the time I booked it. I'm hesitant to call for fear they will screw with the reservation and I won't be able to make it again.
Edit: Just to clarify, I'm not spending the night in PDX and this award didn't take any convincing with AGR at all -- Like me, they just plugged in CHI-ELP and it came up with that routing option.
