	"The Travelmation system, which began providing commercial
service a year ago is designed to find the best price for the flight
that most clisely matches a company's needs."

The service is covered by patent 5,021,953 held by David W. Webber and
Sandra E. Kangas of Travelmation.  I saw it in a review of interesting
patents published by the S.F. Chronicle on Saturday, June 22 1991.

Does anyone know what this patent is for?  Database search?  Solution to
the traveling salesman's problem?  Is it just an application of standard
methods to finding cheap airplane fares?  [Snide comments deleted.]

These opinions are mine, only mine ...
