Forget modernization, these AAI employees cannot even maintain and keep the present airports clean. Whenever I land at IGI (Delhi), the first thing I smell is strong and repulsive smell of disinfectant.
On a recenet visit to Delhi, while I was in the waiting area to board direct AA flight to Chicago, the restroom was in such a pathetic state that I decided to wait to board the aircraft. I heard the samilar comment from an american lady telling her husband about how dirty the rest-rooms were and that it was the worst she had ever seen.
So, AAI /govt employees would do a great service by just doing their house-keeping work efficiently and be courteous to all passengers (Indian and Non-Indian) equally. Leave the modernization work to the companies who know their job.
