Used T2 on INTL arrival myself as well. Agreed with all of galaticos' observations. In addition, not sure if this was a fluke or a change of policy, but my bags were not scanned at exit. The scanner and staff were there while walking out of the baggage claim area, but they were just standing around not in the least bit interested in the flow of exiting passengers. At T1 it seemed they almost always made people line up to have their bags scanned. (Looking for gold, I presume.)

Also missing at T2, the staff checking if you actually got a stamp in your passport right after exiting from immigration (always wondered why they had that check - I think they still have it sometimes at BOM).
