Why is Asiana cheaper than Korean Air mileage?

I'm looking for a mileage accumulation card.

I think Asiana is better than Korean Air.

There's not much difference when you actually ride it.

I think there's a big difference, but I was wondering if there was a reason.

I think a year is long, but it must be worse
I can't use it even if it's very cheapkk

It's hard to use it as Asiana and you can make a reservation for Star Alliance
