Des Manning told KCLR Live they've been busy fielding calls about it and thankfully haven't had any of their customers affected yet.
We run the operation with 55 to 60 per cent punctuality more flight disruptions and cancellations, with 40 per cent of customers unsatisfied.
Hannah Maundrell, editor in chief of price comparison site Money.co.uk, says: "It's so disappointing for Ryanair passengers whose flights have been cancelled especially at such late notice".
Mr O'Leary said: "If they're not satisfied with the alternative flights offered, they can have a full refund and they will all be entitled to their EU261 compensation entitlements".
Ryanair is changing its holiday year, which now runs from April to March, to run from January to December instead. As a result, he explained, the company has too few pilots and cabin staff to serve all flights that had been planned up to the start of the winter season.

It must be departing from an EU airport and operated by any airline OR arriving at an EU airport and operated by an EU airline.More news: Equifax Faces A Class-Action Lawsuit in Atlanta
It's not quite as bad as it sounds - the number of flights in actually less than 2% of the company's total daily flights - but that's not comforting if it's your flight. If you're flying with Ryanair, you can check the status of your flight here.
STV News has asked the airline when the full list of affected flights will be published.
Move quickly and try to reschedule your flight as soon as you find out yours is cancelled.
You should keep any food, transport or accommodation receipts to use when making a claim for compensation.
"Flights are operating as scheduled unless an email confirming a cancellation has been received".
However, news of a mass exodus of their pilots to a rival airline that is setting up in Dublin may prove to also be a big factor in the cancellations.
Ryanair has been running its system at the limit, with 97 percent of seats occupied in August, when the carrier flew 12.7 million passengers.
Compensation is also only payable if the cancellation is the airline's fault.
