The Commission for Aviation Regulation to meet to discuss Ryanair’s decision to cancel some flights because of its problems managing pilots’ leave.
The commission has already said it expects Ryanair will have to pay out hefty sums in compensation.
Ryanair has informed all passengers whose flights have been cancelled up to and including Wednesday, but the regulations say if the notice given is less than two weeks then compensation must be paid.
Questions have been raised over whether Ryanair can advertise and sell tickets for flights, which it may later have to cancel.
The commission says the legislation does not prohibit Ryanair from doing this, however, the airline will be liable to pay refunds or provide alternative flights and pay compensation if there is not sufficient notice.
Passengers who are booked on flights over the next six weeks have been calling on Ryanair to give them more information.
The financial penalties for not doing so will put more pressure on the airline to give longer notice on which flights it is cancelling.
Six flights out of Dublin are among more than 50 which have been cancelled today.
