Ib: Dus - mad - gig rt
€360, Found this on ITA with sample dates June 3rd - June 10th. Minimum stay of 7 days, no stopover allowed. This flight has a return before the start of the World Cup Soccer, so that might be a reason for this low fare. Haven't checked any other dates. Flights I found were from DUS and booked into P-class, which earn 80% (5 cpm ($))
