If you want to do EQPs in comfort and can make the dates work, this is another great option, FRA-DFW-SCL in First, it has long weekend dates for fall, $2,665, but it is 20k miles, with the current 2.0 EQP/mile promo it is at least 40k EQPs, depending where it books. About 6.6 cpp but in unbeatable comfort, lol.
