Concorde Class - I suppose with a suggestion that super first is viable (Singapore Suites) it could come back as a new class of travel. I suppose Airbus is the owner of the name although BA must own the brand.

I was listening to a FA talking to a pax sitting behind me. Ahh you were a regular on Concorde madam? Do you miss her. Not really, bloody uncomfortable. So there's obviously a market for a super first TATL - a couple of thou over the cost of a regular F ticket to keep the riff raff out. No need to provide better hardware. Make the plane beautiful to look at and make it expensive.
