At least three airlines have indicated that they plan to fly normally scheduled DC10 passenger aircraft into and out of Dulles International Airport today.

The Federal Aviation Administration has scheduled a press conference here today on the status of the jumbo jet in the wake of Friday's crash of an American Airlines DC10 in Chicago in which 273 persons died.

An American Airlines spokesman said two DC10 departures are scheduled from Dulles today. They are a nonstop flight to Los Angeles leaving at 5:40 p.m. and a 6 a.m. flight to Philadelphia.

American also listed 5:59 a.m. and 4:52 p.m. DC10 arrivals from Los Angeles.

United listed DC10 departures from Dulles at 11:30 a.m. and 5:35 p.m. for Los Angeles, and a 6 p.m. flight for San Francisco. United listed a 4:35 p.m. arrival from San Francisco and a 4:45 p.m. arrival from Los Angeles.

A reservation agent for Northwest Orient said the airline has a 5:21 p.m. DC10 arrival from Boston and a 5:40 p.m. departure for Portland, Ore., and Seattle.

There were no immediate reports from the airlines of unusual numbers of passenger cancellations on DC10 flights.

A spokesman for United, which is resuming service today after a strike, said the engine mounting bolt implicated in the Chicago crash would be inspected on all United DC10 before operation today. American said all such bolts will be inspected and replaced.
