Lufthansa also confirmed its target to reach 40% capacity level for the entire year 2021, with the operating loss significantly below last year's nearly 5.5 billion euros
The EU will also shut out the Belarusian carrier Belavia from its skies and airports. Lufthansa, KLM, SAS, Air France, LOT and Singapore Airlines were among carriers that announced they would stop flying over Belarus.
"Airlines avoiding the airspace of Belarus may well have an additional time and fuel cost, depending on the route. Longer haul routes will generally be relatively less affected."
Germany's largest airline said it was planning to add around 20 new destinations from Frankfurt and 13 from Munich to locations such as the Caribbean, the Canary Islands and Greece.
COVID-19 vaccines and testing, along with strict hygiene rules at airports and on planes, will be prerequisites for travel this summer, it said.
Lufthansa was granted a 9 billion euro ($10 billion) government bailout that came with conditions to preserve competition including the transfer to rivals of some take-off and landing slots at German airports.
Earlier this month, Condor asked the European Court of Justice to stop Lufthansa from cancelling the agreement.
The airline is still hoping for a strong travel recovery from the northern summer onwards, Spohr added, and expects to run at 40-60% of pre-crisis capacity for the year as a whole.
