There was fog for 2 hours approx 9-10 hours before my flight. Leaving aside whether that's reason enough for a a 90min delay (not in my book), the 30 min delay that showed in the BA app had disappeared by mid afternoon, with an on time departure expected until 1 hour before departure when the delay crept up in 10 min increments every 15mins.
