If what's suggested with regards to the Wizz Air speculation (that they were a lost product to ex Monarch capacity at LTN), hardly shows much of a proactive or confident approach to deliver organic growth from SEN.
Would be very worried if SEN's focus was based around effectively carrying an over-spill of traffic from rival airports. Reality is, slots would inevitably become available in some way, shape or form at some point in the future, at which time the airline would just up sticks and move back/consolidate to wherever (LTN in Wizz Air's case). Sadly, I fear Air Malta could've been enticed on rather similar terms and won't stay in SEN any longer than maybe a couple of years.
SEN needs to attract strategic long-term partners for a sustainable growth strategy. EZY, I think at least for the foreseeable future, is the only airline that can truly deliver that for SEN.
