Anyway to waive advance?
 

I unfortunately waited too long to book ISP-MDW, and lost the $49 promotional fare...I am pretty sure the flights are still wide open, is there some site/place/person that can get 7 day advance seats 5 days before the flight? :-) If not, my error. *sigh*

No,
SWA.com is the best on the net.

Only chance is priceline but then you can not pick your times.

With no cancellation fees on Southwest, it's best to jump on cheap fares early.

It would be nice if Southwest used Ding to offer last-minute weekend fares and fill a few more empty seats.

If the return leg of the trip is still 7 days out, you can book a separate RT (starting with the return) and cancel the back half, capturing the lowest 7 day advance fare (some require a RT).

Oh well, I am gonna just fly flyi then, cause it ends up being cheaper. *shrug* customer lost.
