No shower availability at Delhi airport that a business traveller should consider and I have never been offered an arrival facility when flying in there. The lounges at the DEL airport itself are contract lounges operated by Oberoi and/or Sheraton and/or Maharaja lounge. They are basically the same and provide a more comfortable seating area that is better air conditioned and has basic drinks and nibbles and a very basic bathroom.

I cannot wait until the airports in India are privatized... I really cannot.

On the matter of airport security in India. They do a good job of going through the motions without providing any real security. I can tell you only too easily of the "security" in Srinagar Kashmir ("India's most secure airport"), Delhi (India's second most secure airports according to their own Civil Aviation Ministry) and Bombay's airports.

In Srinagar, Kashmir, if there is ever an incident of any sort within the airport building itself, only a miracle will save one from getting caught in the cross-fire between heavily armed "security" forces automatic fire, who are foolishly placed in a bi-level rectangular set-up most likely to kill innocent bystanders and each other as the guards are armed prinicipally with machine guns and are from various units whose joint-training as a cohesive team is basically non-existent.

In Delhi, I won't elaborate on the systemic weaknesses in security there, lest there are bad apples in the world who would exploit that, but there are some serious flaws.

Bombay airport security I am not as familiar with, but it appears to be much the same as Delhi's.
