Just saw the information below:
"According to TSA, alcoholic beverages can be packed in your checked baggage. Those with between 24% and 70% alcohol are limited in checked bags to 5 liters per passenger and need to be unopened.

Beverages with 24% or less alcohol in your checked baggage don’t need to adhere to the same rules.

When it comes to your carry on, you’re allowed to bring smaller bottles of alcohol but they need to “comfortably fit into a single quart-sized bag,” TSA notes."

My 1st question is: I can bring 6 bottles of 750 ml liquor in my checked bag without problems, right?
My 2nd question: Can my duty-free 2 liters can be additional, right?
My 3rd question is: How much tax should I expect to pay for the 6 checked bottles? Based on their price paid? Based on alcohol content total? Any other metric?

Thanks in advance for your valuable answers.
