CHICAGO (AP) _ A jury on Friday awarded $1.2 million to a former flight attendant who was raped at a suburban hotel and contends the assault aggravated her problem with multiple personalities.

The U.S. District Court jury also awarded $65,000 to the husband of the 31- year-old Denver woman, who was beaten and raped by a knife-wielding man last year at the Caravelle Motor Inn in Rosemont. The victim was not identified.

The woman, who worked for United Airlines, charged the hotel with negligence, saying it had inadequate security. But hotel attorneys, who have not decided whether to appeal, said proper security measures were in place and the attack could not have been avoided.

Michael Domin, 22, of suburban Palatine, pleaded guilty to the rape and three others that occurred from 1982 to 1984. He has been sentenced to 25 years in prison, said Harvey Barnett, attorney for the woman.

Barnett had asked the jury of three men and three women for a $5 million award, but said the $1.2 million was ''reasonable'' and ''will go a long way in helping her with her medical problems.''

''She's in a bad psychological condition,'' he said. ''She can't be left alone. She has a problem coping.''

Barnett said his client was sexually abused as a child and suffered from multiple personalities. While working as a flight attendant, testimony showed, the women carried 12 different name tags and flew under different names.

But Barnett said she still was able to successfully handle her life as a flight attendant, wife and mother to her 3-year-old son and 1-year-old daughter.

''She functioned fine,'' he said.

Since the assault on Jan. 10, 1984, he said, her emotional problems have become more severe and she lapses into multiple personalities, one of them a weeping 7-year-old child.

The attack occurred when the woman came to Chicago to attend a United refresher course after a maternity leave, Barnett said. He said she was grabbed in the hallway of the hotel by a man who threatened her with a knife.

She was taken into her room and assaulted, he said.

Barnett said the woman is undergoing therapy and will need professional help for several years. He said she is not working.
