And yet they are still flying and expanding service...
This does nothing to Norwegian.
Also, just remember that these deals are reciprocal. The U.S. has to play by the rules as well. Let's see what happens when this gets turned around on the U.S. airlines. Only two weeks of vacation, health insurance coverage has to be paid by the employee, no guaranteed pension plan. The U.S. does quite a bit to undercut labour standards of the rest of the first world.
NAI does not have Singapore flight crew and has ZERO employees based in Bangkok, contrary to what ALPA tells you. Norwegian Air Shuttle (NAS) has Bangkok crews. But NAS is registered in Norway, and everything is fully compliant with Norwegian labour law. So this proposed legislation would have ZERO effect on the things ALPA is complaining about. Remember ALPA claims that the Bangkok employees are allowed because of NAI being registered in Ireland, but the two are not connected.
Lastly, will this attempt to block Swiss, Austrian, Brussels Airlines, Aer Lingus, Thomas Cook Scandinavia and others? They are all registered outside the country of their majority shareholders and thus play under different labour laws.
