The aircraft was G-VIIL.
It operated BA189 to EWR on 13th September and landed there 33 minutes late at 8.18pm.
It then spent more than 5 hours on the ground there and departed for LHR at 1.24am on 14th September.Does seem an inordinate amount of time if said to be due to weather or capacity restrictions.No other flight from EWR last night had such a delay.
Delay possibly due to a combination of unscheduled maintenance and weather/capacity restrictions?Compensation claim might well be worth considering.BA188 currently approaching LHR and already more than 3 hours late.
