I land in KIX from Paris next week. Does anyone have any updated experience with KIX immigration? I land at 1030a and am in Business Class so I should be first off the plane.

I am planning for my train ticket and train seat reservation, so I need an idea on how much time to allow.

Also...if I make a reservation and immigration is way longer and I miss the train, will they rebook me on a later train without any penalty?

Thanks!
