Price fighter EasyJet also has to cancel dozens of flights on Monday due to absenteeism among staff.
The airline was also forced to cancel hundreds of flights last weekend due to a staff shortage. That caused chaos at several British airports because passengers were stranded.
On Monday, at least 62 flights to and from British airports will be cancelled out of a total of more than 1600. According to EasyJet, absenteeism has to do with the omikron variant of the coronavirus, which means that people are unable to work.
Since the release of the corona measures in the United Kingdom, the number of corona infections has risen sharply.
EasyJet cancelled at least 222 flights last weekend. To tackle the problems, easyJet is putting extra staff on standby. Nevertheless, the company was forced to ground planes.
