Continental Airlines flight attendants said they had called a nationwide walkout Monday over complaints similar to those against its sister Eastern Airlines, but Continental said no service disruptions were expected and there were no immediate reports of strike effects after the deadline passed.

"I can only confirm that the strike has been called," Myra Clayton, spokeswoman for the Union of Flight Attendants, said Monday in Houston. She said the decision was made among union leaders Sunday night."We don't see any evidence of that at this point," said Richard Boulware, public affairs director for Denver's Stapleton International Airport, at 10 a.m. as the strike deadline began. "We have not received any requests for permission to demonstrate or picket by the flight attendants."

Houston-based Continental's flight attendants voted in December to authorize a strike over wages and have been free to walk out since that time, union president Carla Winkler told the Los Angeles Times on Sunday in a telephone interview from her Houston office.

"If a work stoppage occurs, Continental is fully prepared to operate 100 percent of its schedule," company spokesman David Messing said early today. "We don't feel there would be any impact on us or our customers."

The union has threatened walkouts of this type twice before in the past year, Messing said.

At the main Continental terminal at Houston Intercontinental Airport, Pilot Thomas Adams, arriving on a flight from Atlanta, said all four attendants on his flight knew nothing of the walkout, except what they had heard on a news report.

Trump backing off

Real-estate magnate Donald Trump said Monday he is no longer willing to pay $365 million for the Eastern Airlines shuttle, citing the labor problems that have largely grounded the financially troubled air carrier. He said he wants to cut the price by more than one-third. There was no immedite response from Texas Air Corp., Eastern's Houston-based parent company. In a letter to Frank Lorenzo, head of Eastern's parent company Texas Air, Trump said, "The shuttle has become an entirely different business in that its market share and customer base may be lost for some time to come, if not forever.
