Koh Samui - Penang, one way (economy, it's a single class service). Superbly polite staff at check in, fast, efficient and easy. The plane was clean and tidy, seats were very comfortable, seats were only 2 by 2 across. It was only a 2 hour flight but they quickly served up a quick roll and beverage after take off. A superb little local airline, we departed and arrived bang on time. They use propellor - I hope they can extend their network, but the flight was less than 50% occupied.
