Speaking of High J configuration, PMUA had a track record of it. Here is an example in 747-400 OP (747-200 also had similar configuration).
You can see 36 of former spacious United First seats. 123 seats of former Connoisseur Class/ United Business.
I remember flying JFK-NRT, ORD-NRT, SFO-PVG, SFO-PEK, LAX-HKG and HKG-DEL in this configuration.
