Just a thought, would Aer Lingus consider doing Dublin/Southend in its own right (i.e. rather than Aer Arann as Aer Lingus Regional) now that it has A319 about to go into service?
Would certainly be a London airport where they could avoid Ryanair.. Yes Ryanair could turn up the heat on the STN route by adding Frequency and and dropping prices, but for the catchment area around Southend would Aer Lingus go for that??
