Lufthansa has cancelled 2,200 flights after an outbreak of Covid-19 infections put an additional strain on staff shortages, according to a Bloomberg report on Friday.
The German airline scrapped domestic and regional routes in Europe for July and August, a move that follows 900 cancellations announced earlier this month due to staff shortages.
Labour shortages are wreaking havoc at airports across Europe, as airlines struggle to keep up with demand. In the UK, both the government and the Civil Aviation Authority have intervened, urging airlines to ensure schedules are "realistic" following a bumpy start to the summer season.
Recent industrial action is also threatening a return to business as British Airways workers and Ryanair cabin staff are set to strike over pay disputes.
Lufthansa is also currently in talks with German trade union ver.di, which represents 20,000 Lufthansa ground staff. Workers are demanding a 9.5 per cent pay increase to deal with rising inflation, Reuters reported. The first round of negotiations is set to take place on 30 June.
