FRatSTN
Did you really expect EZY to add destinations for W14/15 after transferring two routes to LTN earlier.
Unfortunately it appears at the moment that STN is lower down the pecking order, bit like FR at luton where there hasn't been a sniff of a new route for over 18 months ( Think Alghero was the last)
There is obviously a lot going on in the background that we are unaware of but for the moment you will just have to ride it out and see what S15 has to offer.
