To answer your question, no. Just because its a intercontinental aircraft with business seats doesn't mean you get lounge access. If you were on a flight from JFK (as mentioned above) or on a TATL/TPAC flight, you would get access.

At ATL, the competition is... Airtran.
Major USA airlines with transcons from JFK, EWR, or LGA with 2 or more transcon destinations:
DL - SLC (JFK and EWR); LAX, SFO, SEA, SAN, LAS, PHX, PDX (rest from JFK)
UA - LAX, SFO (JFK and EWR); DEN (EWR and LGA only)
AA - LAX (JFK and EWR); LAS, SAN, SFO, SEA (rest from JFK)
CO - DEN, LAS, LAX, SNA, PHX, SAN, SFO, SEA (all from EWR)
B6 - BUR, DEN, LAX, LAS, LGB, OAK, PHX, PDX, SMF, SLC, SAN, SFO, SJC, SEA (all from JFK)
