Delhi Transit is not the best, but it works out. You gotta tell that guy that you want to be in Transit before going to Custom. Once in Custom, they will contact you with your luggage. But you have to make sure you have at least 4-5 hours of time before next flight. I would not recommend Delhi Transit for 2-3 hours flight. And dont forget to take IC500-600. YOu need it for Subway or Indian Tea. It is not the cleanest and friendliest. But that is all we got. So use them well. And speak English all the time. YOu will enjoy meeting many nepali from different walks of life and from different corner of the world. It is truely an adventure if you can enjoy. Like Indian Democracy, it is chaotic, but functional. If you get a time, go to Ashoka Lounge and enjoy Naan and Alu Gobi.
