I don't know if this is a Black Friday deal or not, but just booked FRA - DOH - CMB return for $1785 (£1340) via Priceline.com. Found on ITA and there is wide availability in summer. MUC can be had for a little less. A330 & A350 both ways with just ~4 hours in Doha either way.
Google and Qatar.com price this at twice the price.
