Koh Samui routes & carriers
For Asian destinations, one-stop routing is common on many itineraries, so compare the complete journey rather than choosing the first low headline fare.
Before choosing a ticket, compare the UK departure airport, destination airport, number of stops, connection time, total journey time, Business Class cabin, baggage and fare conditions. Two fares with a similar price can offer very different travel experiences.

✦ Getting better value ✦
How to pay less to Koh Samui
Start with the fare, then check what you are actually buying. Look at the aircraft and cabin where shown, the connection, total travel time, baggage and flexibility. For a long trip, a slightly higher fare can be better value if it gives you a more convenient connection or more useful fare conditions.
Try more than one travel date where possible. Compare London with regional UK departures too. For some journeys, a change in departure airport can alter the routing and total journey time significantly.

The current route data includes London, Glasgow, Birmingham, Manchester. The best option can depend on your travel dates, connections and fare availability, so compare more than one UK departure airport where practical.
The route data points to Koh Samui and uses the destination code USM. Check the exact airport shown on the itinerary before you book, especially where a city has more than one airport.
It depends on the departure airport, airline and travel date. Do not assume a route is nonstop from every UK airport. Check the number of stops and total journey time on the specific itinerary.
Business Class benefits vary by airline, aircraft and fare. Check the exact ticket for the seat, baggage, lounge access, priority services and change or cancellation conditions included with your fare.
Compare flexible dates, more than one UK departure airport and different routings. A lower headline fare is not automatically better value if it comes with a much longer connection or less flexible conditions.
For a long journey, many travellers value a more comfortable seat, priority services and a quieter cabin. The value depends on the route, aircraft, trip length and the specific fare you are considering.
There is no single booking window that guarantees the lowest fare. Check prices early, then keep an eye on alternative dates and departure airports as you get closer to your trip.
Yes. Use the enquiry or quote form on the page and provide your travel dates and preferred UK departure airport. Your final quote should confirm the itinerary, cabin and fare conditions before payment.
Check the departure and arrival airports, number of stops, connection time, total journey time, cabin on each sector, baggage and ticket conditions. These details can make a lower-priced fare less attractive.
