The low-cost airline cancelled, "1,700 flights that should have been operated in July, August and September of this year", which will affect around 180,000 passengers, which is equivalent to "less than a day of flights", since "More than 90,000 flights were expected to be operated during the peak summer months," said an easyJet spokesman, quoted by financial agency Bloomberg.

Airlines are cancelling flights in a "preventive action" to limit air travel chaos added the spokesman.

Passengers whose flights are cancelled will be transferred to other flights or may be reimbursed by airlines.

The operational adjustment being made to flights will help reduce the challenges arising from airspace congestion due to the war in Ukraine and delays in air traffic control, the same spokesman said.

easyJet isn't the only airline that has had to reduce its summer schedule.

Ryanair Holdings, Air France-KLM and Deutsche Lufthansa AG have cancelled flights citing controller strikes and air traffic congestion.
