I wouldn't really call a peak of over 300,000 pax per annum, 4 daily 737's and delaying the end date (they might have even done it twice), not making NCL work. I would however call it APD, downsizing of the NCL base in general and more profitable redeployment of the aircraft (I know, not a strong point for NCL but this was when Gatwick was massively starting to become flavour of the day and I think STN lost out as well)
Flybe on NCL-STN was just a travesty from the start, times were crap, wasn't advertised well. Half arsed attempt that ended up on bmi regional's ERJ, 6 weekly at 11am...
I'd love to see another London connection, and this is probably one of very few remaining options
