LBA unlikely I would say; bmi made a pig's ear out of the LBA-LCY route a couple of years back and that experience is hardly likely to inspire confidence in other operators. VLM themselves are generally going backwards on LPL-LCY and MAN-LCY as competition on the railways increases and of course the perception of airport "hassle" is disproportionately bigger, the shorter the sector. NCL-LCY is hardly a high volume route for Eastern, 1236 passengers in September, which gives you about 10 per flight on a 3 x daily weekday service which helps to reaffirm the view that even on high volume UK - London city pairs (e.g Newcastle, Glasgow, Belfast) making LCY work is not easy. Throw in the availability of peak slots at LCY, landing fees etc then it doesn't look good. On the flip side, improved public transport connections around LCY and the financial uncertainty regarding GNER's parent might persuade someone to have another go at LBA-LCY and with the right sort of corporate deals in place, it might just work, Personal view is that 2-5 years from now, the only service into London from LBA (and probably Yorkshire) will be someone like Jet2 into LGW .
