Cloud1,
Of course one should talk about future carriers but it becomes ridiculous, at this early stage, to suggest that SEN's future is in the destiny of EZY and then thread drifts about what if EZY go all A320 rather than A319 etc.
Bearing in mind Stobart needed to buy shares in Aer Arran to get them in to SEN the Irish routes are nothing to sing and dance about but, crikes, the new airport only opened a few days ago, operators are not going to switch airports without seeing the airport in operation.
But Cloud1 ... How can you say, with any certainty, that EZY are SEN's future largest carrier? ... You don't know that any more than the rest of us don't know that ... it's a new airport, it's only just opened, all will become clear in due course and not on day 1!
