Boarding B56/57 - chances of us seated together?

Hello everyone,

This is a Boeing 737 Max 8 (with 175 seats?), what are our chances of finding seats together? Preferably window and middle but aisle and middle is also fine if it comes down to that.

There is also an option to upgrade to A1-A15 for $40 per person, should we go ahead with this instead?

The route is OGG - SJC

Thanks for your inputs!
