My first update...
I pulled up my reservation once again, and my booking class was changed from B/Q to all T. Not that it makes a difference to me (a seat is a seat, and I wasn't doing this for any special promos), but interesting nonetheless.
Idea number one--Continental.com goofed and gave me B/Q class seats but priced my itinerary at the unavailable T class price. Thus, when I actually tried to ticket it, it went ahead and sold me the ticket at the B/Q fare.
