People from the future are dying because of pollution, they travel back to airplanes about to crash and switch passengers who are listed as dying in the crash and bring those people back to their time. In the present an crash investigator finds a device a blonde lady posing as an airline attendant dropped and they meet and he travels into the future with her and there is a paradox that almost destroys everything. 80s or 90s movie... please help, I thought it was morgan fairchild as the attendant but I don't know.
