Bosses at Ryanair have announced that is cancelling up to 50 flights a day for the next six weeks - to make its schedule more punctual.
The airline which is based at Stansted said the flights axed would affect less than 2 per cent of its passengers and anyone hit would be offered alternative flights or refunded.
In a statement on its website the company said the move would:
"...improve its system-wide punctuality which has fallen below 80% in the first two weeks of September through a combination of ATC capacity delays and strikes, weather disruptions and the impact of increased holiday allocations to pilots and cabin crew as the airline moves to allocate annual leave during a 9 month transition period."
Ryanair has agreed to implement measures to ensure all passengers affected by flight cancellations are "fully aware" of their rights.
The Civil Aviation Authority has accused Stansted-based Ryanair of failing to respond to their request of an urgent meeting.
The aviation regulator has given Ryanair until 5pm today to sort out compensation for hundreds of thousands hit by cancellations.
