Airlines hand them out to cover their butts. Sometimes if I'm on the line, I'll collect them. Other times I'll give it back to the passenger.

There have been times when the kiosks go down and we require every passenger to have the old form. When it is found out that the crew did not pass them out on the plane, we will hold the crewmembers on the line until all of their passengers are processed. Sucks for them, but now you'll find crews that pass them out all the time, whether we want them to or not.
