Northwest certainly flew them on intercontinental routes, across the
Pacific, the I believe I remember hearing that their -30s are now used
for Pacific flights while the -40s fly domestic and Europe.  AW&ST
lists the following still air ranges:

   DC-10-10    4,123 miles
   DC-10-30    6,357
   DC-10-40    5,988

It had been my impression that the -40's range shortfall was due to
higher fuel burn with the JT9D engines.
