All Nippon Airways Co. may expand a venture with Germany's Lufthansa after greater cooperation with partners helped the Japanese carrier double transfer passengers at Narita airport.

ANA may form tieups with Lufthansa units Swiss International Air Lines AG, Austrian Airlines AG and Brussels Airlines NV, ANA President Shinichiro Ito said in a March 2 interview.

The Tokyo-based airline began the Lufthansa venture in October after forming a similar accord with United Continental Holdings Inc. last April.
