I'm flying RT LAX to DPS next March and have a few options on how to fly there. I am a OW Emerald (AA EXP) so I would presumably get access to any OW F lounge enroute. Each option is price and time neutral, so I'm most interested in seat comfort and service. I did several searches so I have a good idea of each product, but thought I would see if people had any strong opinions. I could also do one on the outbound and another on the return:

Option 1: LAX-NRT on AA F, NRT-DPS on JO J
Option 2: LAX-NRT on JL J, NRT-DPS on JO J
Option 3: LAX-SYD on QF J, SYD-DPS on Jetstar J

Thanks for your help.
