I can't reserve an open seat on a flight. I select the seat I want and click continue but the seat doesn't "take" on my itinerary. I even tried the old trick to select a seat and then view another leg prior to "conitinueing" to see if that worked. No dice.

I also got an AU on a Y fare but there don't appear to be any seats open in First. Is this normal? I don't think I have seen this one before.
