For many years my impression was that LCY was meant to be a small airport serving the business travellers in Canary Wharf and the City. No it seams that it has grown to a normal airport with flights to typically holiday destinations!
I think that in the current climate operating such airport in the middle of a city is abnormal. Instead of expanding, plans should be made on how to close it down. With improved transport links to Heathrow (Elizabeth Line) closeness to Canary Wharf / City cannot be used to justify it's benefits. I would also argue that job creation is no longer a benefit either as there are so many job opportunities in London.
BTW I have left my comments on the consultation website
