Airplanes are waiting in queue for take off. They are wing-to-wing or tail-to-tail. As soon as one airplane takes off another one lands rright behind it on the runway. No problem in this case. As soon as one airplance touches ground, another one is running behind it for take off. That is worrisome. The runway is as bad as traffic jam at road signals at Bangalore. (ya, I am exaggerating as of now. Wait for few more months for reality).
From the continuous announcements in the airport you can never make out details of your plane. No wonder the staff goes around shouting "Jet Airways to Bangalore !!" "Spicejet to Delhi !!" (like they shout "chai chai"). The only reason people put up with all this is that they save on the travel time as compared to railways. If the waiting period extends any longer, railways will be faster and cheaper. To top it they are all 'no-frills' airlines these days. So if u are lucky u can buy water while u are waiting inside the plane. If you are luckier (i mean waiting for more than an hour) they sell chips. In this aspects trains are better - you are are never starved. Those who consider those vendors as pests, please make note.
Infrastructure in India !! I am lost for words !!
