Spotting locations in India

Hello,

It would be greatly appreciated if you can advise me on the spotting locations at three airports in India listed below;

1) Mumbai/Chhatrapati Shivaji International Airport (BOM/VABB)

2) Bengaluru/Kempegowda International Airport (BLR/VOBL)

3) Delhi/Indira Gandhi International Airport (DEL/VIDP)

In my understanding, it's very tight and/or restricted in India to do the aviation spotting. So, I may keep staying inside of the terminal building, but even at the terminal building, I would like to hear of your advices for better spotting.

Thanks in advance,

Seiji Chiba

Excellent feedback, a tour guide and geography lesson all in one, not forgetting the colourful to-the-point description of the spotting locations themselves. A wonderful day out with a curry from the local kiosk!
