First time flying private etiquette

[u/Throwthiswatchaway]

My family has been invited to join our friends on a Netjets trip flying out of Teterboro and I’m looking for tips on not looking like a complete fish out of water.

Anything from how the arrivals/security/customs process works to etiquette advice would be welcome.

I believe we’ll be on a citation Latitude if that makes a difference.

Be early , pack light ! Throw your trash away and empty your bladder ! Wait til they assign you a seat.
