Not sure how you draw the conclusion that it's clear Westjet don't want to be at LGW, considering they've continued to operate into Gatwick over the past 18 months despite the fact they could've easily got temporary slots into Heathrow. It's also been said many times that existing users of LGW will not let Wizzair get a significant foothold in LGW, as was evident by Norwegian's slot sale to easyJet, but keep repeating the same thing as you please.
