AA first has been a joke for a long time. It was an ever so slightly better seat and they served one extra course - a soup - but was otherwise identical to business class service. You can’t charge thousands more for soup.
First class has been dying for years - and the only airlines that will do it, it’s really a prestige thing more than a profit center.
BA, agree, AF, not a chance. La Premiere is much much nicer than even qsuites. LH is somewhat plane dependent, but the FCT is fun.
