When I travelled while on H1 and AP, this is what happened,
Departure - The airline staff asked me for passport and saw that I have valid US visa or AP. They did not scan the passport or note down its number. Then they issue me a boarding pass.
At the time of boarding, occassionally they ask me for passport but they just look at it and return.
On one of my trips they did not take I-94. I was not knowing about the procedure. When I arrived from the trip, I gave to POE officer. I guess not every international passenger uses I-94 and therefore it is easy to miss by airline staff.
Arrival - I was asked passport and AP papers. The officer asks me few questions but I have no way to now what he sees in computer as it is not at my eye level. But one thing is sure, he does not scan my passport. I do not have any bar code on my pasport.
