Help plan 10 day trip from LAX to ICN/NRT with 1 year old
 

My wife and I will be taking our 1 year old on trip to SKorea and Japan this fall.

United: 345k points
AA: 336k (minimal spend on the Aviator Red Car)
BA: 122k
Pending: expect additional 60k UR from Sapphire banking as well as another 30k from CC spend in next 6 months

I am planning to bring car seat and have my son sit in car seat and fly:
LAX to ICN: 35k/person coach x 3 with Asiana = $105k United
ICN to NRT: $8k/person coach x3 with Asiana = $24k United
NRT to LAX: $50k/person premium economy x3 with JAL = 150k BA Avios

Other option is to do LAX to ICN on Asiana in 1st class for me and my wife only. Would they allow my son to sit on lap/have a bassinet? I wouldn't be able to afford first class for all 3 people.

Have you checked award availability? And real taxes & award surcharges?
For NRT also look at HND

ICN-NRT/HND is a short flight. BA avios can be good for short award redemptions.
AA ff miles is another option for Japan-LAX. But may not be able to get PE

OP's other threads on this trip

I'm confused by the $ signs. Assume OP meant miles not $s.
