Question Tracking down air leaks

I notice that in a few hours my air pressure drops to about 60psi, overnite to zero.

I understand I need to use a spray bottle to find the leaks with the bubbles,

Are there common locations the fittings loosen up?

are the air lines just pushed into fitting or are they tightened with lock nut?

it's a freightliner

Are you talking about air leaks in tires or somewhere else? If tires, The valve stems often leak. Sometimes it's due to a schrader valve not completely screwed down.

Don't waste your time jumping around start in the front and work your way to the rear checking all fittings and valves, give that spray bottle a workout doesn't take all that long.
