Exit row pricing for their transcons JFK-SFO appears to be $25 so if you want it both ways it adds another $50 to your ticket raising the cost to over $500. They mention an additional 6 inches of pitch for a total of 38 inches which implies a standard pitch of 32 inches. While better than average their transcon price is also just that, average. No mention of the cost for the AVOD but I don't believe I read that it'll be free either, just available.
