I recently flew to Singapore on flight 21 April 28, 2024. From the time I was greeted at the aircraft door your cabin crew was warm welcoming, smiling and dressed sharped in their uniforms. I've flown around the world and this was my first time on singapore airline. Jason was very attentive to all of my needs. Kelly did made sure my food was correct and it was served at perfect temperature. Mohan check made sure i stayed hydrated they did a beautiful dinner service and lunch service. Everytime I went to the bathroom Ploy had my favorite drink ready. Even though I was in premium economy they gave us first class treatment. I truly enjoyed everything from start to finish on my flight. Even though this is the longest flight in the world I was thankful for the comfort your crew provided me in this journey. Having this amazing crew will surely bring me back on your airline for my vacation travel to Asia. Please give them a special thanks from me. These are memories I will cherish.

Before traveling to Koh Samui, ensure your passport is valid for the duration of your planned trip date from Thailand. Most travelers, including U.S. citizens, can enter Thailand without a visa for up to 30 days for tourism purposes. However, visa requirements can vary based on nationality, so it's important to verify the specific requirements for your country. Carrying a copy of your passport and entry stamp is also advisable while exploring the island.

Koh Samui is served by Samui International Airport (USM), which hosts both domestic and international flights. The airport is well-connected with direct flights from major cities in Thailand like Bangkok, Phuket, and Chiang Mai, as well as international flights from select locations. For travelers coming from further afield, connecting through Bangkok's Suvarnabhumi Airport (BKK) or Don Mueang International Airport (DMK) is often the most convenient route, with frequent short-haul flights to Koh Samui. Booking flights in advance is especially recommended during peak tourist seasons like the dry months between December and February.

Upon arriving in Koh Samui, it's important to be aware of Thailand's strict regulations on importing certain items. This includes tight restrictions on bringing in plants, food items, and animal products to protect the local environment and agriculture. Customs officials at Samui International Airport (USM) may inspect your luggage for such items. To avoid any issues upon arrival, familiarize yourself with Thailand's customs regulations regarding prohibited and restricted items. This awareness is not only crucial for a hassle-free entry but also helps in preserving the delicate ecosystem of the island.

  • What should I pack for a trip to Koh Samui?

    For a trip to Koh Samui, Thailand's idyllic island, your packing list should cater to a tropical beach environment. Light, airy clothing is essential due to the warm, humid climate prevalent year-round. Essentials include swimwear for the island's stunning beaches, a sunhat, UV-protection sunglasses, and plenty of sunscreens to shield against the intense tropical sun. Casual beachwear is perfect for daytime, while evenings can call for slightly smarter attire, especially if you plan to visit upscale restaurants or beach clubs. A light rain jacket or umbrella is advisable, particularly if you’re visiting during the monsoon season from September to November. Comfortable sandals are ideal for the beach and general exploring, while a pair of closed-toe shoes may be needed for certain activities or dining establishments. Don’t forget to pack insect repellent to protect against mosquitoes, especially during the evening or when visiting more remote areas of the island.

  • What are some activities and attractions in Koh Samui?

    Koh Samui is renowned for its stunning natural beauty, vibrant nightlife, and rich cultural heritage. The island’s beaches, such as Chaweng, Lamai, and Maenam, offer crystal-clear waters and soft sands, perfect for relaxation, swimming, and water sports. For a cultural experience, visit the Big Buddha Temple (Wat Phra Yai) and the beautifully ornate Wat Plai Laem. Nature enthusiasts will enjoy a trip to Angthong National Marine Park, a pristine archipelago ideal for snorkeling, kayaking, and hiking. The Na Muang Waterfalls, with their natural beauty and swimming spots, are a refreshing escape. For a unique experience, visit the Fisherman’s Village in Bophut, known for its rustic buildings, boutique shops, and lively night market. The island also offers a range of wellness and spa retreats, reflecting Thailand’s reputation for excellent therapeutic treatments.

  • Is there public transportation from Samui International Airport to downtown areas in Koh Samui?

    Public transportation options from Samui International Airport (USM) to major areas on Koh Samui are somewhat limited. The most common and convenient way to travel around the island is by taxi or minivan, both of which are readily available at the airport. These offer direct travel to your hotel or other destinations on the island. While there are no formal bus services directly from the airport, shared minivan services can be a cost-effective option, especially if you’re traveling alone or with a small group. For greater flexibility and the freedom to explore the island at your leisure, renting a scooter or a car is a popular choice among visitors. It's recommended to book your transportation from the airport in advance, particularly during peak tourist seasons, to ensure a smooth start to your stay in Koh Samui.

  • What does USM mean?

    This is just an IATA (International Air Transport Association) code. IATA codes are used in aviation to identify and differentiate airports. That’s why a Ko Samui Airport flight would often be abbreviated as a USM flight.
