It's no surprise that the airlines are starting to eliminate their "First Class" services.
Back in the day, First Class described the whole travel experience, not just time spent in the air. You'd get First Class service on the ground before the flight, in the air during the flight, and back on the ground after the flight.
Now when you take a First Class trip, you don't get much except a wider seat and free booze. For First Class trips within the US, there is no lounge you can go to unless go pay for the airport lounge, but many of those are stuffy and outdated anyways.
Additionally, there are no extra services that the airline provides, such as carrying your bags down the jetway for you as you board the aircraft, etc. That sort of stuff vanished when the industry matured.
So I'm not surprised that it's going away - I think the next incarnation of First Class will be the chartered jet, not the commercial airline.
