How can I find out the amenities on board my flight?

I'm flying on United Airlines #968 from New Jersey to Frankfurt on December 13, the equipment assigned to this route next month is the B767-300 - I'd like to know if this aircraft is refurbished or old.

Some amenities i'd like to know is available on board are-

-power outlet

-personal TV

-USB

Thank you

Depends on whether its a 2-class or 3-class.

3-class is the most common and Economy Class has a personal TV and no AC power - Business or First Class has AC power. No USB ports

The 2-class is much less common and has a personal TV and AC power

If you go to the website for the airline you are flying with you can generally get that information.
