skyman771 I think you're getting a little confused. 6G was Air Wales, the routes you mentioned above are operated by Eastern Airways (T3).
Jet2
I suspect we may well see more from Jet2 for the coming summer. If their rumoured plan to base upto 6 aircraft are true then most planes will only operate around 1 flight per day, with alot of non-flying i.e parked on the tarmac. This would hardly be profitable for them to do, NCL being one of the highest in aircraft parking charges. Also alot of flights do not fit into the flight schedule and require extra a/c. For example the 2 weekly flights to TFS. Also BGO flights do slot into a programme well, unless they will be using the 146 LGW a/c?? Maybe we could see SXF and BUD/WAW?
