Ryaniar’s chief financial officer, Neil Sorahan, has hit out at airports for not recruiting enough staff to cater for passengers.
There have been widespread delays amid large scale demand for flights this summer with holidaymakers returning to the skies en masse for the first time since 2019.
Mr Sorahan criticised airports, which he said "had one job to do" and said "various governments" and airports needed to be held to account for "not staffing up appropriately".
While Ryanair has been having a successful summer (posting a £145million profit), passengers have reported long delays at airports.
Mr Sorahan told the BBC Today programme on Monday: “You have to hold ANSPs (air navigation service providers) and various governments to account in relation to not staffing up appropriately for that.
"Equally the airports themselves, they had one job to do to and that was to make sure they have sufficient handlers and security staff. They had the schedules months in advance.
"We managed to staff up for 73 additional aircrafts well in advance and it's incumbent on the airports to get their planning better next year."
The Airport Operators Association said the hubs had been recruiting security staff since late last year.
A spokesman added: “The vast majority of passengers across the UK are now getting away on their holidays with no or minimal disruption."
