In next three years these will need modifications.Cud the authority decide whether these airport will last next twenty years and cater to the air traffic.Look what happened to IGI Delhi,commissioned just 20 yrs. back and choking now.Look at Mumbai airport. Compare these with only domestic airports of USA or even China and see the difference.Came back from USA just two days back and cud'nt find a toilet paper rool in IGI Delhi on arrival.Shame on Indian airports.In addition look at the tardy and pot bellied cops and custom people.India shud learn a lesson from Dubai,Bangkok,Beijing,Hongkong and other Asian airports(What to talk about European/US/Canadian airports).Look at these airports and see how they clean and maintain them compared to sparrows and pigeon nests in the deperture lounge of IGI.Show off atleast where it is required as the first impression of the countries the tourists visit.
