First class doesn't make much sense. Hardly anyone pays for it and it costs the airlines a bundle. A lot of airlines are getting rid of it, even the all mighty SQ
, and going with expanded business class and premium economy instead. Everyone knows that airlines make 60% of their revenue from business passengers so it only makes sense to expand the business class service.
There will always be first class, but that will be limited to a very small number of routes.
With the cost of private/semi-private jets continuing to go down, people who can affort $10,000+ for a ticket, will not put up with the herds and airport non-sense to fly on a regular carrier. You're seeing that happen today already.
Actually, as someone pointed out, in the US domestic market first class is no more than a fare category or a label. No one really offers first class service anymore. Most domestic F cabins I've seen on AA
, don't look like first class to me at all.
