You win some you lose some. I have to go to a funeral in Worthing next week and would almost certainly have used NQY/LGW to do it, however, NQY/LHR is not ideal by the time you have cleared a busy airport and picked up a hire car I could have almost driven there at a fraction of the cost. On the other hand I will almost certainly be using the LHR flight for our trips to YVR with BA.
