Ryanair has agreed to implement measures to ensure all passengers affected by recent flight cancellations are "fully aware" of their "rights and entitlements".
This will include passengers receiving full refunds or being booked onto alternative Ryanair flights or "other comparable transport options", with reimbursement of "reasonable out-of-pocket expenses".
The airline made the statement after meeting with Ireland's Commission for Aviation Regulation.
The UK's Civil Aviation Authority has accused the Dublin-based carrier of "not complying with the law" over its handling of the fiasco.
Ryanair has pledged to send a "clarification email" to customers outlining their rights and explaining how and when they will booked onto other flights.
On Wednesday the airline cancelled an extra 18,000 flights for the winter season, including four months of flights between Belfast International and London Gatwick
Ryanair is facing a multi-million compensation bill for cancelled flights after it previously revealed it was shelving up to 50 flights a day up to the end of October.
It says the cancellations were brought about because of an error with pilot holiday rosters.
