I've been having the same identical problem. The page loads the top blue banner - and nothing else. I even sent an email query asking what I could do to resolve this (no answer, of course).
When the page hangs, I simply keep hitting the backward and forward arrows until the page I want eventually loads. The only time this doesn't work is when Spybot warns me that "Avenue A" is trying to download to my computer. When that happens, I know I won't get into Flyertalk at all no matter how many times I hit the arrows - so I just quit and come back later.
But getting back to the problem - is there anything that can be done about these hanging pages? It is SO annoying! And SO frequent!
