when i booked it, i didn't realize that if you didn't pay an extra $10, then you got no seat assignment at all. errrr....... that may have been worth it, but too late now. the flight actually looked pretty empty, it's a weekday flight, to a dest that they nwa is flying to almost every day.
they did offer FC for sale for $125 each, showed 4 seats taken (we bought about 2 1/2 weeks to departure).
i'll update after the trip next week!
