It used to be possible to access pretty much any flight's live seat map using a string on www.checkmytrip.com and replacing the salient details, as follows:

This no longer works. It was great, because one could very quickly check to see upgrade likelihood, on multiple airlines. Does anyone know of a similar way to check this seat info easily? It's such a slow process going directly to check airline's web site.
