Apologies in advance for not being able to get this info somewhere in the web (my list of links mysteriously vanished this weekend) or from my travel agent (it's a long story!).

Any idea what the load is like on this flight? I'm trying to decide whether or not to upgrade to J, but if I'm pretty safe at getting an empty middle seat beside me I'll stay in Y. I'm on a full fare ticket and won't have status (Elite) until March 1.

Thanks!
