AA weren't the only culprits, and were not the only ones fined for
doing that.

AA, Continental, and Braniff, I think. But American developed the
practice, which Continental later adopted.
\
Braniff never flew DC10's, and their 747 maintenance was largely
contracted out (up til about 1980, they only had 1)

I tried to find the facts via surfing but I could only find mention of
AA and Continental. However, at the time it was announced that
three airlines were fined as a result of the ORD accident. I was
working in the airline business at the time, and the three separate
fines were big news to us.
