Article is in italian I couldn’t find any news about this in english but i believe it’s really important to share.
"Sono attesi dagli 80 ai 90 aerei all’aeroporto Marco Polo di Venezia. Jet privati da Los Angeles, New York, Londra e Dubai scaricheranno in laguna un carico scintillante di star, imprenditori, supermodelle, influencer e tycoon. Il traffico aereo privato sarà talmente intenso da richiedere un coordinamento speciale tra l’aeroporto di Venezia e gli scali di riserva a Verona e Treviso. "
Translation:
"80 to 90 planes are expected at Venice’s Marco Polo airport. Private jets from Los Angeles, New York, London and Dubai will unload a glittering cargo of stars, entrepreneurs, supermodels, influencers and tycoons into the lagoon. Private air traffic will be so intense that it will require special coordination between Venice airport and the reserve stopovers in Verona and Treviso. "
Thanks for the calculation. Sounds about right, according to the link below the top of the ladder billionaire flies about a couple hundred times a year and consumes about 2000 tonnes of fuel. So the fuel consumption you calculated is about 70 billionaires. It is generally true that the top hundred richest people in the world consume/obtain about as much resources as the rest of the world so that calculation is believable.
