I love OOBWS. Live in ATL. Bid Senior in NYC. Get rid of trips. Pick up easy broken-up trips for OOBWS in ATL to fill up. GS in NYC. Normally I wouldn't give away my strategy but I'm senior enough now to not worry hehehe.

PS...you can scalp easy OOBWS outside of the base you live in as well with DH on each end qualifers. My favorite OOBWS last year: DH MSP-ATL. DH ATL-CHS. 10 hr layover. Fly CHS-ATL. DH ATL-MSP. It was glorious
