Asiana said that the Fast passes are filled out at the desk in Korea and they did not have extras.......
Thursday night at 1am it was a mad house , the second "domestic" immigration area was backed out to the main walkway ,
I think it was all the Chinese flights started using that side !

​​​​​and not shown buy the pictures above is how small the current Fast Passes are , just Passport size now , half the size of the old ones
