Is there any way to see the seatmap for a Frontier flight on their (or other) web-site? I am thinking about standing by for a later flight and would like to know how tight it is going to be and if I should spend the $25 confirmed fee.

I tried a dummy booking and there was a choice for seat selection based on seatmap, but I got to the credit card entry point and did not get the seat selection.

My company's travel agent site will give me the map, but I am blocked from accessing flights less than six hours out. Standby is at four hours, so another way to access the map would be ideal.
