This seems to be a good reference for the differing types of airlines and their seating. Haven't checked it all out completely yet but for starters SAA and Delta are on here. Just found this tonight. Hope you all like it. www.seatguru.com

thanks for the link. i checked my business class seat assignments from LA to Sydney next month, didn't like them and called Qantas. they were very accomadating and changed me to my preferred seats. thanks again!

Yes, Seat Guru can be very useful. Just remember that there is a pleathora of variations of planes of a given model. Unless you know the exact variation your flight is using then the seatguru website is of limited use.
