South Korea has two hometown carriers: Korean Air (KAL) and Asiana. These two airlines are expected to merge, pending government approval in 2025. But until then, each airline is operating their own lounges at their hub in Incheon. KAL has several outposts in the huge airport (shower suites, a la carte dining, beautiful design—oh my!), with specified locations for first and business class passengers. Asiana has their own lounges as well, but Priority Pass members can access the business class lounges when flying with Asiana or Star Alliance-operated flights. Singapore Airlines also has its own lounge here, and the Oneworld alliance (which includes American, British, and Cathay) has a group lounge here. Beyond the lounges, if you’ve got some energy to spare during your long layover, try a guided transit tour run by the airport itself. Depending on how much time you have, you can go to nearby temples and palaces—and even one of the most fashionable districts of Seoul.
