Similar question, little bit different situation.

My agent booked a flight for next saturday, but I got no seat assigned.
I guess this is because the flight was fully booked and probably even the wait list was closed, and probably the agent used my FB status to get me a ticket.

A few questions:
Is there a way to get a seat except for the 30hrs checkin?
Does not having a seat assigned increase my chances of being bumped? I seem to recall something to that extend in another thread (quite a while ago).
Or does it increase my chance of an op-up (although Y is also listed as full).

(Btw: this is AMS -> HKG next sat)

Thanks alot! FM
