“We want to substitute our A340 fleet at some point,” he said in an interview in Frankfurt, where Lufthansa has its hub. “We’d rather grow with bigger planes. For Swiss, the A380 is hardly an option, but we’ll look at the Boeing 747-8 and 777 and the Airbus A350. We’ll have to see what makes sense.”
Personally, I think the A350 might be a more logical choice, as it offers full flight deck commonality with their (very new) fleet of A330-300s. But Boeing might of course be very willing in offering an attractive package for the 747-8, and LX of course has full insight in the experiences of LH with the airframe.
