Transatlantic
 

I am trying to find transatlantic cruises for November/December 2012. So far, I can only find the Queen Mary from Cunard. Is this too late for repositioning cruises from the other cruise lines?

The Queen Mary is the only liner doing regular Transatlantic cruises. If you aren't finding any others, then they may not exist.

There are dozens. Do a search on any of the main cruise booking sites (cruise.com, vacationstogo.com, cruises.priceline.com, ...).

There really aren't that many, JP. Check out Royal Caribbean, Princess, Seabourn, Carnival and Celebrity. TAs are pretty much done by the first week of December. Hope you like cold, bouncy seas.

Yes, but November is part of November/December (and a number of the November ones last into December).
