Avianca Taca Holdings has announced that it is in talks with Boeing, Bombadier and Airbus about a potential order for between 50 and 100 new single aisle aircraft. The decision is expected by the end of 2011.

“From Boeing we want to see a more efficient, more modern aircraft,” said major shareholder German Efromovich. “If that takes new engines, or composites, or whatever, we don’t care -- whatever they’re going to offer we’ll compare it with the Airbus A320neos.”

The airline is also talking to Mitsubishi Aircraft Corp. about regional planes that could replace older Fokker planes.
