Besides PIK from Derry, there are still BHX, LPL and STN which are also UK domestic flights. Can you tell me where to find load factors and yields? Or is that just inside information?
On the other subject, two reasons why STN-BVA and STN-CRL have little potential: distance from the city centre (STN, BVA & CRL, ruling out business traffic) and proximity of both Brussels and Paris to the canal tunnel (Making car and train so much faster). FR does operate the very short flights EIN-STN and NRN-STN, which are doing very well, and from December they are starting MST-STN (I have my doubts, route was tried before and failed)
