Hah, I'm going through OO training right now, and we learned how to onload pax from the waitlist. The instructor did say that sometimes you'll get offers and stuff from the nonrevs (I'm going to Starbucks, do you need anything?) even though it doesn't really change anything. Personally, I do it for the karma, and to thank them for the help in tricky situations.

Oh, and I think y'all would like to know that we did get a few words about nonrev karma... putting them in an exit row seat when possible, or the best seat available at the time
