EZY may indeed have taken two A.319s away for the summer, but they are operating 30% more flights by A.320 in S13 compared to S12 so the weekly loss of seats is around 9,000 (seats, not pax).
And 9,000 seats less each week for 30 weeks (aprox. length of summer season, start of April to end of October) comes to 270,000 less seats for just the summer season.
I think LPL will be extremely lucky to escape a reduction in EZY's winter 2013/14 timetable compared to the winter 2012/13 timetable so potentially that's even more seats lost.
With EZY's impressive Load Factors, I think the loss of 300,000+ seats in one year is going to lead to a reduction of more than 180,000 annual passengers. So unless EZY flights from LPL are only just over half full, the passenger number reduction is going to be greater than 180,000, and I often wonder if Ryanair inflate their estimates a little!
