Keane, who joined AirMiles in 2003, left last week to return to her native Ireland. She is joining Edelman's Dublin office as consumer brands account director in September.
Prior to AirMiles she was communications manager for BAA's Heathrow Express. She also formerly worked at British Waterways.
AirMiles, which has retained Cohn & Wolfe for 18 months (PRWeek, 23 January 2004), said it had no plans to review its relationship with the agency.
