Ironic but it sounds like the most likely complaint and one to appeal if the airport wins is actually Bournemouth airport on the grounds of unfair ability if having the extension for Southampton to take business away from Bournemouth. Didn’t seem to stop hurn letting EasyJet in to fly Edinburgh and Belfast which could arguably be core routes for Southampton and Southampton’s core business without a runway extension. Case of we have the longer runway which I don’t believe Sou argued against at the time but how dare you try and make airbus a320’s become viable from your runway! Can see this getting ugly between the two airports.
