Am surprised that FR don't split their ondon operation across STN & LTN like it does with NOC & KIR.
Not necessarily demanded warranted to LTN from either ORK/SNN as there's for e.g. 4-5X Daily ORK-LHR, 2-3X Daily STN, 1X Daily LGW in total 7-9X Daily flights to LON, from NOC thats just 1-2X Daily ORK-STN, 1X Daily LTN, 1X Daily LGW in total 3-4X Daily flights to LON.
