Delta Air Lines flight DL224, an Airbus A330-941, was taxiing for departure when the captain (CAPT) noted discomfort in his eyes and the first officer (FO) detected a slight odour.
After takeoff the flight attendants (FA) notified the CAPT of an odour detected mid-cabin and the relief first officer (RFO) was tasked to investigate. The RFO did not notice any odour. Several minutes into the flight the FA notified the CAPT that several FA were ill and that passengers were complaining about the odour. The flight crew carried out the quick reference handbook checklist items for smoke / fumes and recalled the RFO to the cockpit so that the CAPT could assess the cabin. The CAPT assessed the cabin, and at about position 43°02' N, 065°03' W the flight crew coordinated with ATS to return to KBOS. The overweight checklist was carried out and the aircraft landed at KBOS without further incident. The aircraft was met at the gate by emergency medical technicians and the CAPT, FO, and five FA were transported to the hospital. All were released after medical evaluation.
Maintenance personnel inspected both engines and the auxiliary power unit for oil leaks and conducted engine run tests to isolate bleed air sources. No odours were detected. The forward recirculation filters were replaced, and the aircraft was returned to service.
