"That is not true."
Here is the law. You can decide for yourself what is true or not:
"This Regulation shall apply:
(a) to passengers departing from an airport located in the terri-
tory of a Member State to which the Treaty applies;
(b) to passengers departing from an airport located in a third
country to an airport situated in the territory of a Member
State to which the Treaty applies, unless they received
benefits or compensation and were given assistance in that
third country, if the operating air carrier of the flight
concerned is a Community carrier"
To the best of my knowledge no US Carrier is registered in the EU. A "Community Carrier" means one whose aircraft bear a EU (or Norwegian or Swiss) registration.
