Kandahar International Airport IATA: KDH now has flights on Ariana Afghan Airlines [www.flyariana.com] & Kam Air between Kandahar, Dubai every Wednesday Ariana & Monday Kam Air; as well as three domestic flights per week between Kabul and Kandahar and one Domestic flight from Kandahar-Herat-Kandahar every Tuesday by KamAir. Pamir Airways has daily morning flights from Kabul which is cheaper than Kam Air and Ariana Airlines. Flights are also available by the UN & ICRC but are only open to UN staff and other approved organisations.
A good highway, the A01, links Kandahar to Kabul. However, passing through Zabul province is not safe. The Highway from Kabul to Kandahar is nowadays quite safe apart from regular patrolling of security forces. Total drive is of 6 hours but can take 12 hours if there is patrolling as US Forces do not allow cars to overtake them. The highway from Herat is also being improved, again it is very dangerous where it passes through Helmand and Farah. Highway A75 which runs south towards Spin Boldak and the border with Pakistan, then continuing to Quetta is also very dangerous.
