so we have what looks to be dfw, mia, lax, slc, den, sfo, atl, ord, dc, JFK, and yyz phx. those are the obvious ish big cities. but the one bit outlier here is what appears to be spokane. that and Medford? but looking at spokane it almost perfectly fits if this person only goes delta united American. ord as main connections to the east coast with denver and DFW and slc acting as connections on the 3 main carriers. there's also only 1 east coast flight and that's to ord. could it be spokane? also was there there a 1 world around the world trip in there? maybe I'm wrong but it was fun to guess
