Even if you have to use any route into Belfast including M2/M1, Saintfield road, etc etc between 0700-0930 in the morning 1600-1800 in the evening and you want to catch a plane or arrive back in the province forget it. And any way if your plane arrives in after 2330 or so, or its windy your up to Aldergrove any way, then in a bus back down to the City to get your car, then your stuck in traffic (if its windy during rush hour). So really operating hours of Bhd are 06.30-07.00, 09.30-16.00, 18.00-21.30 for the travelling public with regard to road congestion. The only problem is no LHR at Aldergrove, no signs of Emirates yet anybody
