## Discrepancy

FLT 0221 - EN ROUTE FROM PHX TO AUS PASSENGER AT SEAT ROW 18 COMPLAINED OF NOXIOUS ODOR THAT CAUSED EYES TO IRRITATE. FLIGHT ATTENDANT ALSO SMELLED NOXIOUS ODOR FROM REAR OF CABIN TO SEAT ROW 6, ODOR EVEN CIRCULATED INTO THE FLIGHT DECK AREA, DIVERTED TO SAT AND LANDED WITHOUT FURTHER EVENT. MAINTENANCE TRIED TO DUPLICATE ODOR BY RUNNING BOTH PACKS WITH APU, AND THEN WITH BOTH ENGINES, NO ODORS WERE NOTED. INSPECTED BOTH PACK BAYS, THE OVERHEAD DUCTS, THE ENGINE AND APU, AND THE CARGO COMPARTMENT AREA, NO DISCREPANCIES WERE NOTED. FOUND COALESCER BAGS EXTREMELY CONTAMINATED, REPLACED BOTH COALESCER BAGS.
