A test booking today threw up two additional destinations available from Luton - Milan and Glasgow, both in direct competition with EZY. Neither route features in the online timetable. I suspect a glitch!
Has there been no BE flights from LTN in previous winters?
This winter saw a break in both IOM and JER flights between about Jan and Mar. Also, bear in mind that BA have started IOM-LCY flights recently. I suspect BEE do not have critical mass at Luton, so these flights are not core business for them. If they increased frequencies on these, moved on to the Waterford route, and perhaps moved some flights up from LGW they would start to generate more local awareness and could prosper.
