Ryanair achieved a 12% rise in passenger carryings last month despite ongoing strike by French air traffic controllers.

The budget carrier saw passenger numbers rise to 10.6 million in May over 9.5 million in the same month last year.

Last month’s growth saw the airline’s rolling annual traffic increase by 16% to 108.5 million passengers.

The May load factor was up by two percentage points to 94%.

Chief marketing officer Kenny Jacobs said: “These record monthly numbers and load factors were delivered, at lower fares, despite the ongoing disruptions being caused by ATC strikes in France, as lower fares and the continuing success of our ‘Always Getting Better’ customer experience programme continue to deliver even more great value for our customers.”

Passengers carried by eastern and central European low-cost rival Wizz Air in May were up year-on-year by 21.8% to 1.9 million with an improved load factor of 90.1%.

The airline is introducing the new wizzair.com website with an ‘Express Booking’ function available on mobile devices and soon to be introduced on a desktop version.

The Wizz Air fleet increased to 68 aircraft with the introduction of a new Airbus A321neo and the carrier expanded its network into Montenegro.
