Atlantic Coast Airlines Upgrades to United's Revenue Management System.

DULLES, Va.--(BUSINESS WIRE)--Nov. 16, 1998--Atlantic Coast Airlines ("ACA") (NASDAQ/NM:ACAI), the Dulles-based United Express carrier, Monday announced that it will upgrade to United Airlines' enhanced revenue management system, "ORION".

ACA expects to begin realizing the benefits of this new system early next year.

"We are delighted to be able to utilize United's system at the same time our network is experiencing tremendous growth from regional jets," said Kerry Skeen, president and CEO for ACA. "The 'ORION' system will help manage the thousands of different passenger origins and destinations that flow over our combined systems every day."

"ORION" represents the latest in revenue management technology and is designed to manage entire passenger itineraries rather than individual flight legs. "ORION" uses IBM's "Deep Blue" computer to process the large number of complex calculations involved in this analysis.

In addition to the state-of-the-art inventory management control provided by "ORION", the transition will also expand the number of booking classes available on ACA flights. These expanded booking classes will allow ACA to broaden the number of products offered to customers, while simplifying booking procedures.

"The customer has told us that they expect the United Express product to be seamless with United," said Tom Hanley, United's director of interline programs. "This transition is a major step in our combined effort to make the United and United Express networks fully integrated."

Atlantic Coast Airlines offers more than 500 daily departures system-wide serving both Washington Dulles and Chicago O'Hare, which are major hubs for United Airlines. From its major hub at Washington Dulles, the airline offers 230 daily flights to 47 cities.

On Dec. 15, the carrier will service six cities with 17 departures from Chicago O'Hare International Airport, and ACA's route system will span from Maine to Florida and as far West as the Dakotas, serving 53 destinations in 24 states.

At that time, the airline will operate a fleet of 74 aircraft, including 14 50-passenger Canadair Regional Jets, 32 29-passenger Jetstream J-41 and 28 19-passenger Jetstream 32 turboprop aircraft. ACA employs over 2000 aviation professionals.
