You get interrogated for no reason after putting no one in danger, but the FA is allowed to make the saftey announcement in an unsafe manner, which could have a negative impact on people's ability to survive if there were an emergency. Seems like US has its priorities out of whack. Is power-tripping passengers more important than ensuring their saftey?
I think you should suggest to the FAA that you know an airline that deserves one of their $10,000 saftey violation fines.
And I think you're owed some compensation for the US FAs who lied to the feds and filed a false report against you. This is not just bad customer service, it's illegal.
Big thumbs down to US; you should take your business elsewhere.
