I remember reading about this in Crain's when they were talking about rolling it out at MDW (before ORD), I swear they said the money was to be pooled and divided up amonst the Skycaps and no additional tipping would be expected

. We always use the Skycaps but must have flown AA last November and June because I'm pretty sure I would have remembered paying double for the Skycaps.
I'm flying SW (MDW) for the 1st time in 13 years, do they have Skycaps?
TIA,
Alice
