In the early 1980s, typical round-trip coach airfares from the East Coast to London were more than $500. Then Freddie Laker introduced the People's Express, a competing service into Newark at $350. Major airlines matched his price and did so until they drove People's Express out of business. Then prices shot back up to over $500. A lawsuit filed under the Sherman Act resulted in a judgment that the major airlines had explicitly tried to destroy a competitor. The People's Express case is an example of on the part of the major airlines.
