American Airlines First Class
At American Airlines, there is only a real first class named Flagship First in the Boeing 777-300. The alignment is like in business class (1-2-1) and otherwise, the seat is (unfortunately) more reminiscent of a good business class, but at least it is a lot more spacious. The swivel function of the seat is quite unique so that you can look straight ahead through the window during the flight.
Especially the soft product still has a lot of room for improvement. Here are a few relevant reviews:

Most European passport holders can stay in Argentina visa-free for up to 90 days.
This deal requires immigrating to the United States twice. Most Europeans need an electronic system for travel authorization (ESTA) to enter the USA for up to 90 days. This costs US$40 (~€34) and you should apply for it a couple of days before your trip, at the latest.
There are some cases where you cannot apply for an ESTA, e.g. if you’ve been to Cuba since 2021 or to Iran, Iraq, Syria, Sudan, or North Korea since March 2011. In those cases, you’ll need to get a visa from a US embassy or consulate, which can take multiple weeks.
