Depending on desired dates of travel, you may find 4 business class seats, 2 seats, or zero seats. Availability on NH operated flights will be better if you book through ANA Mileage Club than through UA. You definitely don't want to transfer any of those Chase points to either program until you can confirm availability of seats.
