Lufthansa is to cut over 3,000 flights this summer due to staff shortages on account of Covid-19 and strikes.
Germany's flagship airline is cancelling both domestic and European routes for July and August, adding to Europe's travel chaos right in the midst of the crucial summer vacation period.
The news comes as a second wave of announcements was confirmed on Thursday, and relates to 2,200 flights - or 3% of those scheduled.
The airline already cut back 5% of summer flights on Fridays and weekends, including 900 connections and said several bottlenecks and shortage of personnel meant the entire European aviation industry is facing staff shortages.
Unrest between workers seeking wage increases to keep up with inflation is adding to the problem, with strikes also threatened or underway at rival airlines including Ryanair Holdings and British Airways.
Although travel demand has increased, a Lufthansa spokesperson noted infrastructure has not yet been fully restored.
