"We started into the summer with about 10% of passengers and 15% of flights compared to pre-crisis levels", Jens Fehlinger said.

Lufthansa is currently running about 55% of the flights it used to. While it is serving 192 destinations - more than in summer 2019 - it is flying many routes less frequently.

The airline and its subsidiaries are using 520 aircraft, compared with roughly 800 before the crisis, Fehlinger said.
