Yes, I need to get to Osaka. I had heard about the train option, but am trying to avoid having to drag my suitcase all over, since I am packing for 3 weeks.

What's the difference between kix and itm? Which would be better/easier to fly into? How close are they to the port?

I am thinking I would rather fly. If I make a reservation from nrt to kix or itm separately from my original award reservation, will they agree to check my luggage straight through? That is, IF I flew out of nrt the same night I arrived. That obviously isn't an option if I fly out the next morning.

Thanks for being so helpful!!
