AA/QR: ATL to BAH from $2810 (Bus)

Seeing this on Google Flights but not ITA Matrix. Allows me to get to Payment details on AA.com. Not sure if better routings are available. Mostly AA (ATL-PHL-DOH) with a sprinkling of QR (DOH-BAH in "First"). I guess you get the F lounge before the BAH flight on the outbound? Google Flights Link
