Ryanair's announcement last Friday that it would be cancelling up to 50 flights a day for six weeks has created huge uncertainty for its passengers.
It is estimated that around 350,000 passengers could be directly affected by cancellations, though many may not realise flights are cancelled until shortly before their departure date.
Ryanair this evening published details of the majority of the cancelled flights. Details for this Thursday, Friday, Saturday, and Sunday followed.
Here's a breakdown of how events have unfolded since the story emerged:

- The Commission for Aviation Regulation said Ryanair will have to pay compensation to passengers whose flights have been cancelled with less than two weeks' notice.
- The airline had so far given people notice of sometimes just hours, and at most five days.
- Ryanair says the disruption is because of difficulties it is having managing a transition of its leave year from an April to March model, to the calendar year of January to December, as required by European regulations.

Saturday 16 September
- Ryanair said the cancellation of flights was happening because the airline "messed up the planning of pilots' holidays".
- The airline apologised to "the small number of passengers affected" and said they can take a full refund or travel on a later flight.
- In a statement, the airline said cancellation notices had been emailed to customers up to and including Wednesday 20 September.
- Ryanair published a list of eight cancelled flights, all either to or from Dublin.
Friday 15 September
- Ryanair announced it would be cancelling up to 50 flights a day from its schedule for the next six weeks, up to the end of October, due to a backlog of holidays for pilots and crew members.
- The airline said it was taking the move in an effort to improve its system-wide punctuality.
- It said that the cancellation of between 1,500 to 2,500 flights accounts for less than 2% of its flying programme over the next six weeks.
