Avoid Delhi as much as you can. Someone here mentioned box of chocolates...I really really think its like a sour wine, that you know its going to be sour and still drink it! Last summer, I went with my Fiance and had 12 hour transit. They bother you so much that you think you are living 1974 once again. They ask you for proof but they dont know what I20 is, they ask you things like "what is your relationship with each other?" etc.... its crazy... when you stay at the airport then you realise that inequality in India is growing ever more than before. People working in the airport are so so backward and they allow smoking in the lounge only for foreigner!!! My lungs are screaming to say "They are only white, they have nothing..!!!" I would never go back to Nepal via Delhi. Thats like ruining your vacation.
