It looks like Korean only charges 30k points
for a coach ticket even if booking a Hawaiian flight, and from a quick review of their website there seems to be more availability.
Most programs charge, say, 25,000 miles for a round - trip coach ticket anywhere within the Lower 48, or 60,000 round -
trip for a coach ticket between the U.S. and Europe.
Redemption values to Argentina are also good — 30k SPG
points for a coach ticket and 60k SPG points for a business class ticket.
I think their goal is for everyone to redeem (and pay with cash)
for coach tickets, and then upsell premium cabins at T - 24 for elites, and at the gate for everyone else.
