It has emerged that more than 1,000 flights were cancelled by Ryanair across September.
Ryanair have partly blamed this on the recent "collapse" in the air traffic control system in Britain, specifically two air traffic control (ATC) issues in the UK within two weeks of each other last month.
This comes amid growing pressure on the boss of Britain's National Air Traffic Services (Nats), Martin Rolfe, with calls for him to resign, including from Ryanair, amid several air traffic issues, which resulted in the cancellation of thousands of flights across the industry last month, with hundreds of thousands of passengers heavily affected.
They also mentioned ATC strikes in Belgium and general disruption across Europe due to volcanic ash clouds from Mount Etna eruptions.
One recent stance was caused by a "connectivity issue" at its Prestwick Centre in Scotland, unrelated to an ATC software malfunction on September 8, leading to widespread chaos.
The seriousness of these calls for Mr Wolfe to step down from his role, has led to Transport Secretary, Heidi Alexander calling for a meeting with Nats chairman, Warren East, former chief executive at Rolls-Royce to discuss these problems.
This is set to take place over the coming weeks.
The latest figures from Ryanair, shown that it had operated more than 111,700 flights over the last month, which carried over 20.1 million passengers, an increase of 4% from the previous year.
Their load factor, otherwise known as the amount of seats on each flight, increased by a steady 94% last month.
Wizz Air also revealed that the amount of passengers flown over the last month had increased by 24%, moving up to 7.78 million, with capacity increasing by 25.3%.
Wizz Air have said that they plan cut its flight programme by 5%, for the second half of 2026, due to wider Iran war pressures on the travel sector and the ongoing increases in fuel costs.
It was also revealed that shares in the company had moved higher than in Dublin trade.
All this comes a matter of weeks after Ryanair's boss, Michael O'Leary had recently apologised for referring to rival airlines as "high-fare rapists", a remark heavily criticised by the Dublin Rape Crisis Centre.
