I can't seem to book a standard award ticket. For example I see a PVD-BWI-LAS award ticket open. I get all the way to the purchase page and I get the error:

"OOPS! Seats were not available on the following segments of your itinerary: BWI - LAS. (SW900001-eKBMCEcLSRieDajCq6r1Jg) "

I've now gotten this error on 3 different legs. I attempted to call but was on hold for 2 hours and hung up. Anyone else getting this or have a solution?

Thanks!
