Well, I don't know much about Mr Tinkler but I hope he doesn't lose interest in SEN completely. The development of Carlisle suggests that he sees SEN as at least a medium-term asset rather than a finished product to be sold on.
As SWBKCB said, where indeed would SEN be without Stobart....?
EZY seem to have settled into a small but viable operation now. Hopefully they will try to expand again at SEN once their new fleet of neos arrives and LGW is fully exploited. In the meantime it would be good to see one or two more continental-based airlines using SEN. Scandinavia might indeed be a successful market - there used to be streams of Norwegian and Swedish DC-6s, C-46s, Viscounts and Convairs bringing shoppers into SEN back in the 1960s.
