nike, great idea.
I have 40 yr old pax ask me to fill in their logbooks! I always take the log book to the flight deck to get the correct mileage. Tech crew and I look at the flying history and are amazed at the amount of travel some children do.
My airline (QF) doesn't have them anymore, although there has been talk of bringing them back. The ones I usually see are the old BA log books, often 2 or 3 of them glued together.
