On back of EWR-CPT getting started, here are some more fun seasonal routes I wish UA would look into:

EWR-RAK
EWR-MCT
SFO-DPS
SFO-BCN

and of course...SFO-BKK

Unfortunately I’m not sure any of these are realistically routes that would have high J spend for leisure...I would venture DPS Sheryl because of length, but Bali is a pretty cheap place to do in luxury.
