Huge Jet2 increases from some airports for high Summer '18 whereas LBA, as I write has gained about 3 flights per week [net] to the Med. in August. Losing Dusseldorf after many many years of year round service and further reduction to Amsterdam in high Summer. Can't help feeling LS's HQ on the hill is now saturated for routes that are yield viable from one of Europe's most pilfered catchment areas.
