EI Knock Gatwick
Just a note on NOC LGW. There as comments saying that NOC LGW was not viable for FR XL or EZY.
Well this is not exactly true. If EZY had been left to its own devices and FR had not ran in after them it probably still be flying. The level of capacity on the route was not sustainable and not at all profitable for anyone. In fact at this time when both carriers operated the route, none of the London Knock routes were profitable. However, NOC LGW did attract about 60k pax that year. NOC LGW is just as sustainable as STN or LTN, FRs greed meant that they were running everyone else out of town and then making passengers fly to STN or LTN where they could get lower charges.
XL found it impossible as the brand was not known in NOC and besides FR dropped the prices so so low to keep there chances of getting established very poor.
Best of luck to EI on the route, but I would be surprised if FR dont join them on it.
