Some people tend to forget that November is a "dead" month in our little part of the UK when it comes to passenger numbers.. at this time of year its really only the London routes perform decent numbers throughout the week.. most other routes are peak weekend traffic and the "winter suns" even take a dip in numbers.. it'll be quiet until round the 7th December when students start moving around and shortly after that you get everyone travelling at Christmas..
Can't comment on BHD-STN, thought it would see better numbers by now, but as for BHD-AMS, N.I doesn't need 2-3 flights a day during the quiet winter period going to AMS, during summer.. most certainly
Welcome to winter
