Looking one and two days out, SEA/DAL
Tomorrow - F2 Y6 / F4 Y0 - pretty full flights, if not close to or oversold in the back.
Wednesday - F4 Y6 / F3 Y1 - same.
LAX/DAL
Tomorrow - F2 Y0 / F0 Y6 / F6 Y7 - sounds like 2 of the 3 flights will be sold out. Once you're below Y7, you're pretty much good as full.
