Everytime I've flown with this aircraft I experience the poor quality air. Over the past five years I've probably flown 20 times on this type with BA, Aer Lingus and a black one (titan rings a bell). Every one had the same tinge of oil in the cabin air. It's not like a burning oil smell it's more a smell of exhaust fumes with unburnt fuel/oil. It's a shame because apart from the air it's always been a pleasant flight with plently of room as opposed to the usual EMB types.
