X-centric may have been
has been around long enough to spot rubbish
but he seems to know remarkably little about the terms and conditions of his fellow Ryanair pilots. He may even consider the conditions of Ryanair pilots at other bases not to count when he talks about "his Ryanair". But that does not entitle him to make the type of bare faced assertions he made or, in a very Ryanair-like way, to quibble over the blindingly reality about leave availability and Crewdock.
I have no reason to suspect your motives for posting here on his behalf (he may well be on his holidays). However, there is a trend here on pprune regarding Ryanair that you may not have noticed. A large percentage of "Ryanair line pilots" posting here to challenge what is said turn out to be remarkably unwilling - even when presented documentary evidence - to utter the slightest criticism of Ryanair. They either disappear, or ignore / dodge the challenge. If
X-centric acknowledges that Crewdock has been unavailable for the booking of leave for Jan-March that would be a fair start. He would only be acknowledging what we all now know to be true.
