From LAX, the only decent mileage runs (3 cpm) that don’t involve an overnight, but do require a red eye are trips to Florida (MCO, MIA, FLL, TPA) or Puerto Rico. You’ll find some relatively cheap flights to SIN, NRT and LHR, but recently that’s it. They each require an overnight. SIN requires LAX-DEN-SFO-SIN-SFO-DEN-LAX to get a decent cpm (~4.5 cents). May starting in IAH to SIN would work. The deals, when they happen, are fleeting and not even close to the glory days of 2018 and 2019.
