Airshow
I was on the CX250 (LHR-HKG) on Jan 1st - Airshow was working fine although the estimated arrival time on Airshow compared to that displayed on the window on the top right of the IFE screen (and on the handest) was out of sync by about 1/2 hour or so.
Airshow was correct by the way.
I guess they must be fed from diffrerent sources ?
