I would like to point out to any CSR (Chase Sapphire Reserve) holders that most Tokyo flights on UA or AC in biz are available with "Points Boost" where you will get 2 cents per point cash credit for your airline purchase. UA sees these transactions as cash payments thru an OTA, so you will get full PQM and RDM. Prices on the Chase portal for biz fares are exactly the same as those on the UA and AC websites.
