He said: “And then also the wonderful news that the daily French Air Traffic Control strikes will continue for the month of April. Daily.
“We are all collectively facing daily cancellations of flights that aren’t even operating to and from France, while the French protect their domestic flights.”
Mr O’Leary said Ryanair had to cancel 230 flights last weekend due to the strikes, while he said more than 2,000 flights were delayed.
easyJet’s CEO, Johan Lundgren, said that easyJet had also been “very badly hit” by the delays and said “it’s difficult to see when it’s going to end”.
