Mom and pop has two whole floors at the top of an Upper East Side apartment block, with her own apartment within it. I wonder whether there are actually more of these people around now?
There probably aren’t more of them? But they are probably vastly more wealthy now. That’s just the way western society has gone.
Concorde was never, ever, ever about pandering to the ‘cheap and (un)comfortable’. That was precisely why it made significant profit for BA.
Once travel restrictions are eased, it likely still would, as the pandemic has seen many of the richest increase their wealth. Quite possibly one of the very rare aviation sectors to have stood a chance of healthy recovery?
