1.Can I bring my luggage with me for the train ride? My luggage is big and it is a hard covered suitable. If yes, where should I put the luggage, with me at the seat, or there is designated area for luggage?

2.I understand there is a luggage delivery service at the airport. Which company is more reliable? Can I request for the luggage to be delivered on the same day to Gifu as I am staying only 1 night at Gifu?

3. Any other way to send my luggage to Gifu?

Yes. JR limits luggage to a maximum of two large pieces of luggage per person. I guess that Meitetsu has similar regulations.

Since it is an airport train, I believe there is designated luggage space.

It might be possible for at a surcharge, but I am not sure.
