As far as I am aware, A6-ECB is the only EC series aircraft with the old ICE S3000 IFE system. A6-ECA, A6-ECC to A6-ECZ were all delivered from Boeing with the eX2 ICE Digital Widescreen system fitted. Probably an anomaly due to -ECB being a 2 class aircraft as opposed to the rest of the EC series (except ECY and ECZ) being 3 class long haul aircraft.
