ETA, the seat maps on usairways.com are wacky. The -200, for example, shows a 2-3 config, when the -200 is 9 rows of 2-2 (with row 9 spanning the width of the cabin). What gives?
Row 9 really is 5 across...there is a seat in the middle where there would normally be an aisle (~really~ good legroom). The seat map, in its own strange way, is trying to accomodate for that.
