How many people enjoy flying during a non-peak hour of Midnight - 5AM? These are times when a domestic airport should be CLOSED!
I am a foreign citizen living in India and frequently travel by all of the airlines - Jet, King Fisher, Spicejet, Air Deccan, Go Air, each and every one. Rather than imposing a ridiculous fare hike for peak and non-peak hours, the national government and the local state governments need to modernize the airports. Invest in larger airports, build additional runways, hire better trained pilots, stop using airforce bases as airports, fix the speaker announcement system and signs in airports. The only good thing at an Indian airport is the luggage carts are FREE!
In the last 5 years, India has made great leaps and bounds with the low cost carriers and providing people with an opportunity to travel and connecting the country. The highway infrasructure is still poor and travel by road, even on super highways, is impossible. The government has failed to plan for an increase in air traffic and throwing another tax on travel will not solve the problem at all. It will only hurt and further burden the airlines.
Of all the airports in India, New Delhi domestic airport should recieve a Failing grade in all areas. To be the capital of India, with local travelers, business travelers, tourists, etc, it is a very poor image of a 21st Century India.
