Are airline open skies still open in the US?

In early 2018, when the US and the governments of the UAE and Qatar reached a truce over the years-long subsidy debate between American, Delta and United and Emirates, Etihad and Qatar, many questioned how long the cease fire would last.

The answer was: barely a few months. American argued that fellow oneworld member Qatar Airways could be violating aspects of the agreement through its stake in Air Italy, which was adding services from Milan to Miami and New York JFK.

The argument continues to simmer, but proving that Qatar is in fact violating the terms of the truce could prove difficult.

Nonetheless, it did appear to many foreign governments that the highly influential Big 3 were trying to turn the clock back to an era where national airlines were protected from competition, regardless of the wider national interest.
