My partner & I recently flew Sydney/Seoul (Incheon)/Prague & Paris/Seoul/Sydney business class. As there was no direct same day connexion SYD/PRG the airline gave us overnight STPC (stopover at carrier's expense) at the Hyatt Regency at Incheon airport, including transfers, dinner & breakfast, which was a great way to break this always long & tedious trip to Europe. On each of our 4 flights the cabin staff were unfailingly smiling, friendly & polite, happy to assist with any query. We felt this warmth & friendliness genuine, not just plastic. The cabin (upstairs in the 747 bubble on 2 flights) was quiet & spacious & (almost) flat bed seats very comfortable. The food was really good, especially considering most airline food, hot & tasty. Access to the lounges made life much more pleasant, especially on our 4-1/2 hour transit at ICN on the return when we were able to shower & change clothes. I thoroughly recommend Korean Air & would not hesitate to fly with them again, probably the best airline I have flown.
