I was looked after extremely well on the flight, the staff were overly helpful and seemed really positive and happy. I was offered everything that I needed, from ear plugs due to an upset child behind me, to drinks even without a drinks cart nearby. We had slippers provided, toothbrush and toothpaste and continuous snacks offered. I have never flown 1st or business before, but I'm guessing the service would be something similar to that. Korean Airlines is miles ahead of most of the other airlines I have used before. Recommended.
