I have an upcoming one way travel with the ps segment SFO-EWR and I have two questions.

1) Which day/time combination will give me best chance for upgrade to business class? I can choose between Sunday (8:50pm, 9:50pm, or 10:45pm departure), or Monday (9:50pm or 10:45pm departure).

2) Should I try using the RPU, or that's a risky game and it's better to just buy up to business? If the latter, is it better to do it through the website/app ahead of time or wait until gate and do it there? How much does it cost to upgrade with cash?

Thanks in advance for all the answers or pointing me to the right place on this forum where I can find them!

Have a great day!
