Narrative:

During flight it was apparent that the flight attendants were experiencing severe allergic reaction to something in the air. There was severe dust accumulation around reading lights in aft of aircraft. At one point passengers in rows 10 through 13 were complaining about the air quality and the strong force of air coming out of the vent in their rows. The captain was notified of problem; a recurring problem in the 767-300. The captain adjusted airflow. Shortly thereafter when the airflow was increased again flight attendants experienced severe sneezing and runny noses which lasted throughout the duration of the flight. It was at the debrief at the conclusion of the flight that flight attendant #5 complained of severe sneezing on both segments of the flight. Flight attendants #4 and #3 had also complained and experienced sneezing and runny noses on both segments of flight. Flight attendant #5 had been observed by me to have extremely red; watery eyes shortly into the flight although she had reported to duty looking normal. It is apparent that aircraft has a problem with its ventilation system and filters need to be replaced. It is also very apparent that most of 767's I have flown have had similar problems and I have experienced severe allergic reactions since october of 2008. It needs to come to the attention of maintenance and management that there is most likely a problem in the frequency of aircraft ventilation system cleaning and maintenance.
