Hey, don't get confused. Just take the trip. Check luggage all the way to KTM or had to take them out of Indira Gandhi Airport, what's the difference. They'll be out, and with you, so what's the big deal - and if you're planning to bring 5 suitcases, act like a 'sahib' from the US of A - flash your Americal passport, if you have one and speak no Hindi, if you know it - and get the aiport porter to take them out for you. Talk to some one at the airport to take you to the aiport hotel - relax in there. Since most flights go through one or the other foreign city, New Delhi is not that bad. I have been through there a couple of times and through Karachi and Dhaka as well. So, cheer up, look forward to enjoying yourself in Nepal.
