A few more pieces of info:
As stated before: the kiosks are at the left side of the immigration hall
As I came thru Thursday I asked the human traffic cop if I could use them, she glanced at my immigration form and said, " not from your flight"......it was not very busy Thursday at noon anyway.
At the immigration interview I asked why certain flights couldn't use the kiosks.
I was told the airlines must furnish a passenger list in advance.....if they didn't, then those flights couldn't use the kiosk. The airlines are supposed to supply the passenger manifest ....it's just random which flights failed to do it in time.
