I once worked for a company that was, apparently, under pressure from its pilots that there was shortage of drivers, and thus they wnated a bigger slice of the cake. There was a little hestitaion from a draconian management, then the sigh of relief as all the Australians turned up crying for a job. "What shortage" the managers cried. Later on the same argument, and then Eastern US went bust, and US pilots flooded the market, and received validations as the managers convinced the local politicians & authority that there were no local captains.
So that solves problem No.1.
Next, the DUB base. Sounds good, until you read that RYR can re-base you as required. So, DUB in the first month & anywhere else thereafter. Hm!?!
