RYANAIR is facing pressure from consumer bodies to publish the full list of flight cancellations, as frustrated passengers have blasted the airline online.
The airline announced on Friday, September 15 that they were to cancel 40-50 flights a day for the next six weeks to allocate annual leave for cabin crew and pilots.
Since the announcement, Ryanair have published details for cancelled flights until Wednesday, September 20.
But the airline has not given any indication for which flights are cancelled past that date.
Travel editor for Which? consumer magazine Rory Boland said: "Ryanair cancelling many flights at short notice will cause huge inconvenience and great distress for its passengers.
“It’s also essential that Ryanair release a full list of flights that will be affected so that passengers have as much time as possible to make alternate arrangements.”
In a statement this morning, the Commission for Aviation Regulation in Ireland said Ryanair must offer passengers a full ticket refund or alternative flight.
"If Ryanair cancels a flight, it must offer you the choice of an alternative flight at the earliest opportunity or at a later date of your choice subject to the availability of seats or a full refund of the ticket," the watchdog advised passengers.
But compensation for the cancelled flight, which is separate from a refund, would depend on a number of factors.
"First, Ryanair may have to compensate you if it has given you between two weeks and seven days’ notice of the cancellation but your flight departs more than two hours before your original departure time and four hours of the original arrival time, or half these time periods where the notice period is less than seven days."
The watchdog also said the compensation in the event of a cancellation also depends on the distance of the flight and the reason for the cancellation.
Passengers have taken their frustration with the airline to Twitter, with many pleading for more information on their flight.
Have 2 trips booked in the next couple of weeks. Excitement of trips now replaced with worry! Not good. Won't be flying with @Ryanair again.

Previously, Ryanair's Robin Kiely said the airline's on-time performance had been affected by the delays and strikes, and by cancelling flights they could 'restore punctuality' to the service.
"This increased leave at a time of ATC capacity delays and strikes, has severely reduced our on-time performance over the past two weeks to under 80 per cent.
"By cancelling less than two per cent of our flying programme over the next six weeks, until our winter schedule starts in early November, we can improve the operational resilience of our schedules and restore punctuality to our annualised target of 90 per cent.
"We apologise sincerely to the small number of customers affected by these cancellations, and will be doing our utmost to arrange alternative flights and/or full refunds for them.”
Ryanair have said passengers are notified of cancelled flights by email and have published the full list of cancellations up until this Wednesday, September 20 on their website.
The cancellations, which include Dublin, Stansted, Manchester, Gatwick, Edinburgh and Glasgow, can be found on their website here.
