When I was a kid (early '80s), I remember being in the car when we dropped my father off at the airport. I have the impression that, at the time, it was standard for a skycap to meet you at your car and ask if you needed help with your bags--they would unload the bags from your trunk and take them from there. Somehow this service has been transformed into a second checkin line that just happens to form out on the sidewalk, but they're still expecting the same tips. Am I missing something?
