I would say 50/50...experience

I had to quarrel with the airlines staff at Delhi on my way to KTM b/c of the weight of my luggage. Apparently, the weight limit is different for the Delhi to KTM flight. My luggage was passed from the US for the Delhi flight. The weight of my luggage was exactly what they allow here (don't remember the limit though). However, before boarding the flight to KTM from Delhi, they were asking me for more money for the extra weight I have in my luggage as the Delhi to KTM has lower weight limit. I ended up fighting with them and not paying, but it was a hassle. I had to talk to a lot of managers before I was let on board for the KTM flight. They were not willing to give me my boarding pass if I didn't pay for the extra weight. I would say, only if you can fight when they try to give you unnecessary hassle, take the Delhi route. After all, it is cheap.

BTW, when I opened my suitcase when I reached Nepal, a brand new cell phone was missing from its box. Not sure if this happened at Delhi or in Nepal though.   

Same thing happened with a guy who I met on the plane on my way back to Newark. His weight was passed at KTM. He had a couple of extra pounds in his luggage though. Continental crew tried to stop him at Delhi and asked for more money. Poor guy was threatned and told that he would be sent back to KTM if he didn't pay. I stayed with him and fought for him. With two of us fighting against their policy they finally handed the guy's boarding pass saying that the travel agent who booked his ticket paid for the extra weight. What a lie...I even filed a complaint after I came to the US but all they did was apologized for the inconvenience and mentioned that different airlines have different weight policy and it was legitimate for them to charge for the extra luggage.

Anyways, guys....help everyone create a better experience in the future....do not just pay if they ask you for some money. I know it is easier just paying a couple of extra bucks than to deal with the hassle, but it is not right. Let us all fight together in such cases so that such activities by these mofos get discouraged in the airport. Fight for it. I know they will try to threaten you saying they will send you back to where you came from but its all BS. They can't do shit. I experienced it first hand , both ways, to and from Nepal. Do not just pay the fees and pamper these mofos.
