(AP) Lossmaking German carrier Air Berlin says it has sold a majority stake in its frequent flyer program to Abu Dhabi-based Etihad.
Air Berlin said Tuesday that it expects to receive 184.4 million ($242.7 million) from the sale of 70 percent of the program.
Etihad already owns a 30 percent stake in Germany's second biggest airline, which has been struggling in Europe's highly competitive travel market.
Air Berlin reported a loss of 271.8 million for 2011, up from 97.2 million the previous year.
The sale of its frequent flyer program is part of the oneworld alliance member's cost-saving drive. Others in the oneworld alliance include British Airways and American Airlines.
