It was on 727s. I think the interiors were palletized. I remember them flying out of IND too. Mainly to the cruise ships.Depends on how it's configured. UPS actually experemented with using some of their airplanes for pax flying on weekends in the late 1990s-2000 time frame. Can't remember the airframes, but it was out of ATL. I think it lasted for about a year, so it must not have been cost effective.
