How can NOC with no catchment area possibly support two carriers on one route?
Where did the 567k passengers appear out of in the last year then?
I'm guessing the only reason there was such huge demand for LGW when Ryanair and EasyJet were on it, was the resulting bargin fares of having those two cutting into each other. I wouldn't expect any less than Ryanair to restart LGW and close it again if XL Pulled off the route.
