What is the use of having an AIRPORT in a city , if after arriving their in 45 minutes ; you need another 2 hours or more to reach to your destination; which is the main business area and from airport to main business area if the road is famous for traffic jam?! From Dhaka to Chittagong you can easily go by plane in 45 minutes but after starting from Potenga to reach the main business area like Agrabaad, GEC more or Chandgao, you need 1 to 3 hours because of traffic jam; so it is over all 4 hours where in AC Bus you can come from Dhaka in 5 hours. The Air Fare cost should have its value worthy to the Passengers. It is good to have airports outside main city but it need to also ensure that from airport to city the route need to be smooth & Clear. There should be flyovers from airport to center of the city.
