I've read bits and pieces of the raw threads (very little help for me) and the summaries, and looking at it with fresh eyes since I hadn't been involved this season, I would say no airport in the US is safe from being the final destination city airport at this point. TPTB could even do a fake out and have teams fly to the final city via Beijing from Hong Kong and that would open up even more direct flights. Anything is possible.
Only thing I'll suggest is that on paper, areas with recent natural events such as hurricanes and fires are probably less likely, but who knows? I certainly don't.
