Getting around Pakistan is not always comfortable, but it's incredibly cheap. The state-owned Pakistan International Airlines (PIA) has scheduled flights to many domestic terminals and daily connections between the major centres. One of the bonuses of flying is that some of the air routes, especially to the northern areas and Chitral, are spectacular. Buses go anywhere, anytime - but the treacherous mountain roads make the going very tough. Vans, wagons, pick-ups and jeeps are also popular forms of road transport. Train travel is slower and easier on the nerves but there are no routes into the mountains. City transport is dominated by buses, taxis, auto-rickshaws and two-wheeled, horse-drawn tongas.
