The air freight arm of Germany's Lufthansa
The current solution of scheduling take-offs and landings only before 2200 CET and after 0500 CET was just a stopgap. It costs money and does not pay, Karl Ulrich Garnadt told Focus, according to an excerpt of an article to be published on Monday.
If necessary Lufthansa Cargo may have to part ways with its freighter fleet in the long-term, consisting of 18 McDonell Douglas MD 11 planes, Focus quoted Garnadt as saying.
The magazine said around half of Lufthansa Cargo's freight is transported via passenger planes.
Previously, Garnadt said the night flight ban at Frankfurt, imposed in October, would hurt earnings by around 40 million euros ($53 million) a year and sales by over 100 million euros if it were made permanent.
Lufthansa Cargo made an operating profit of 249 million euros in 2011, but said it would be unable to replicate this in 2012 due to overcapacity, a weak Chinese market and the night flight ban at its Frankfurt hub.
