With the latest updates, it appears that the ability to search for fares by specific fare class is not working. On several routes I was pricing, selecting the "lowest refundable fare" radio button caused the site to just give me the lowest, most restricted non-refundable fare. When I selected "full fare" I was shown some O and U fares, but no full Y fares. When I selected "specific fare classes" and entered "Y" I was shown the same O and U fares as before.

When searching for the same itinerary on my corporate travel agent's site, I can see full Y fares, so I know they're there. But Continental.com is suddenly not letting me see them on some routes.
