Given how hard it has been to find F space on CLE flights at times--especually on RJs, I can only hope that there may be another version in the works.
My first thought was that they were showing a 175 seatmap and it had something to do with Shuttle America being folded into Republic as of a couple days ago, but unless I'm mistaken the 175 has 12 F (4*3) --does this seatmap match any current UA aircraft config? None is coming to mind...
