Thanks for the suggestions/advice.
The NRT/HND transfer is new to me now that HND is a second Tokyo gateway. I was thinking of either lugging bags or having them shipped via takkyubin (sp?) before asking the board.
I don't know much about inter-city transfers in the US since I generally fly point to point from SFO. I know LGA exists, but have never flown there.

I was thinking at first since HND is promoting itself as an int'l gateway that they might have had some sort of arrangement, so decided to ask the question.
On to the Bus!
