I was 12-years-old when my family boarded an airplane that took us from the San Francisco Bay Area to Los Angeles
Wait, you were the only two people on the plane? Ok, which one of you was the pilot and which one was the copilot?

(12 years old) No hyphens.
I was 18 years old, I flew to San Diego to go to boot camp, the Dept of Defense paid for the airline tickets, there were 17 of us headed for the Marine Corps, and I don’t know how many were headed for the Navy.
Back then, the Marine Corps‘ and the Navy‘s San Diego boot camp bases were located right next to each other, separated for some portions of their territory by fences. The Navy closed its San Diego recruit training command in 1997, after 74 years of operation (1923). The Marine Corps has continually maintained recruit training in San Diego since 1919, or 102 years.
