Ryanair cancellations.
The EU flight compensation of eu250 ,is only applicable if the cancellation is advised within 14 days of departure, so I would expect Ryanair will be doing all possible to advise passengers travelling in Oct as soon as possible to avoid incurring liability.
The fact that these September cancellations are being advised so close to departure ,suggests the resource shortages have only been identified as critical very recently i.e within the last few days ,otherwise I'm sure they would have adised Sep canx at least 14 days in advance,even if on a rolling basis , to avoid this element of liability.
