A brief summary on RBC.

The article discusses only a small part of the luxury market, but I will still highlight the important:
"The former gold standard of private aviation — sipping champagne
on starched linen [tablecloths] — has largely become a thing of the past for this group of clients," says Robinson. According to him, new clients are looking for "specific types of water," such as artesian brands Fiji and Acqua Panna".

P.S.
What are we going to do?

Maybe it's the starched linen tablecloths? 🗿
