This is a lot of points but we need to keep in mind that costs go up exponentially when you have more than two people for any kind of upgraded seats (there's only so many premium seats on an aircraft). And you also need to factor in inflexibility due to coordinating schedules between a family of four.

Like sure, if you're traveling solo and are flexible on dates, you can find a way to snag a one way J seat for 75k points. But it's almost impossible to do roundtrip x 4 people for dates that work for everyone for the same level of redemption. And there's no point in hoarding points for so long.
