Lufthansa attributed much of the improvement to a €623 million benefit related to a reduction in its stake in Amadeus as well as the
sale of loss-making BMI, the latter of which dragged down 2011 earnings by €285 million. Lufthansa in November unloaded a 3.61 percent stake in Amadeus in the capital market and transferred its remaining 4 percent stake in the travel technology firm to the Lufthansa Pension Trust. Operating profits for the group's passenger business, including Lufthansa, Swiss and Austrian Airlines, fell 26 percent year over year to €258 million. Passenger group revenues increased 6 percent year over year, with traffic up 2.4 percent and capacity up 0.6 percent. Lufthansa reported that "income in the corporate customers segment fell by 2 percent in 2012." Corporate business accounted for 38.6 percent of the passenger group's total revenue in 2012, according to Lufthansa's annual report.
