American Airlines says it has found no problems with a plane diverted to Ohio this month after flight attendants reported dizziness and four passengers fainted.
A spokesman for the Fort Worth, Texas-based airline said Thursday technicians found no operational or mechanical problems and nothing related to cabin pressure. The plane has returned to service.
The April 1 flight with 132 people onboard was headed from Washington, D.C., to Chicago when the pilot dropped oxygen masks and landed in Dayton. Two passengers were taken to a hospital and released. A flight attendant was kept overnight for observation.
A passenger said there were problems with the air conditioning and cabin pressurization system before the plane took off. Some passengers complained of fumes.
American spokesman Tim Smith says fumes from outside could have entered through air intakes.
