I've been looking at a late August break today and Maribor came up because the days it operates match the days I've been looking at travelling.
Regardless of whether it returns next year or indeed gets poached by another airport, what is positive for SEN is that loads are reportedly good and based on the £314 return quoted for two weeks time, they are filling it without dumping bargain-basement fares on the market.
The Stobart figures are also promising - nothing spectacular but Munster seems to be continually creeping upwards, Groningen is doing OK and Rennes looks a good solid route. If the Skywork loads are maintained perhaps they really will keep it as a 'leisure' route as indicated.
Perhaps there is room for some cautious optimism rather than the negativity I've seen here lately.
