World’s elite told private jets BANNED for Queen’s funeral
Foreign heads of state, including Australian Prime Minister Anthony Albanese, have been banned from using private jets and helicopters to get to the Queen’s funeral — and told to take the bus instead.
Yes there are quite a few smaller airports around London. As of course you will know, Heathrow (business) and Gatwick (tourist) are the two big ones for flights to the US.
London City is sited very close to the financial district. It did at one time run flights to New York City but now it's all more local stuff. I remember travelling to Luxembourg from there.
Airport is owned by a Canadian pension fund I believe :)
