I love Japan as much as the next person but no way I would take a connection these days - with all the inherent risks - if a nonstop is available. Adding more hours to a 15hr trip is also not appealing. Plus you won’t be able to do my favorite thing which is to pop into Tokyo for sushi.

Agree with most of the comments - if you need PQP then the UA flight seems like a no brainer. Even if you don’t the 75k RDM is a significant sweetener.

SQ food and service are stellar, and would be my first choice if that’s your primary consideration. But I’m typically skipping meals now on the CIA jetlag diet.
