Ironically, I think SWAPA actually produced such a report (by copying DALPA's, but still). ALPA has a full summary in PDF in the Economics Library, but it's not available publicly, so I can't link to it.
Here's just a quick summary of the highlights so I don't have to type out the whole thing:
United: 16% B & C Fund
Delta: 15% B-Fund (sorry, I was off by a % in the earlier post)
Hawaiian: 15% B-Fund for all newhires (up to 19.4% for pilots hired pre-2005)
Alaska: 13.5% B-Fund
AMR: 14% (match only, thanks to the bankruptcy)
USAirways: 10% B-Fund now, same as AMR when merged
SWA: 9.3% (match only)
