"It's an airport of the privileged in the heart of the poorest burgh in the whole UK belching out a fair amount of noise to get bankers to NYC on an exec A318 rather than cross town?"
Interesting. Were you aware that the A318 is, according to the microphones measuring the actual departure and arrival noise, the quietest aircraft operating from LCY today? Far quieter than the 'Whisper Jet' 146 of yesteryear or the Avro RJ of not-quite-so-yesteryear - and significantly quieter than the Embraer 190?
