WAT may resume in March, local journalist has revealed flights to London will resume in March. Airport preference was LTN and there was a report it may be Flybe.
Would expect SEN to be another fail if it was to be it.
I expect it will be SEN as part of the Flybe branded Stobart expansion. I can't see FLYBE coming to LTN or going back to WAT- they're to busy gearing up LHR etc. at present. While it didn't work last time SEN is a bit more established as a "London" airport now.
We should know tomorrow.
