I know AirTran does, but it was only $10 off. However, $20 r/t is still $20. The thing you have to keep in mind is that as far as they go, you have a contract to sign, and you can only pay with ONE credit card. So every family, couple, person...whatever it may be, can't pay separate for their ticket(s). Most airlines are like that with group sales though. My aunt booked our tickets through Delta and Continental and didn't use group sales for any kind of discounts, but was able to call and book us in several different groups (4 to be exact) so that she could use two credit cards to book it. She said the lady at Delta was very helpful. At that point we didn't even want to bother with group stuff because we were so annoyed with AirTran, but I'd start calling around if I were you. The prices they offer you may be completely different than what you find online also, so don't forget that! Good luck!
