When are flight tickets to Thailand cheapest?

To find the cheapest flights to Thailand, choosing the right time to fly is extremely important and helps you optimize costs. Below are the periods you should prioritize when booking:

Month 5 – month 9 (low season)

From month 5 to month 9 is the rainy season in Thailand, so visitor numbers drop and airlines often launch promotions with fares lower by 30-50%. This is an ideal time to travel to Bangkok, Chiang Mai, or Phuket at a lower cost. If you don’t mind the rain, you should book during this period and prepare an umbrella or raincoat to make your trip more convenient.

Fly in the middle of the week

Instead of flying on the weekend, when demand is high and ticket prices are expensive, you should prioritize choosing flights on Tuesday or Wednesday to save money. In fact, ticket prices on these days can be cheaper by as much as500.000VND -1.500.000for round-trip tickets. If you can arrange your schedule, fly midweek and book early for the best price.

Choose less popular flight times

The prime flight times from 8h to 16h are usually more expensive because they are more convenient for travel. In contrast, early-morning flights (5h – 6h) or late-night flights (after 22h) are often significantly cheaper. If you want to save money, prioritize these time slots and arrange your rest schedule reasonably to avoid fatigue.

Tips for finding cheap flights to Thailand from SimPM

To find cheap flights to Thailand effectively, you not only need luck but also the right strategy and supporting tools. Below are tips from SimPM to help you easily “catch” the best fares:

Use incognito mode

When you search for flights many times on the same browser, websites may store your history (cookies) and automatically show higher prices by recognizing your demand. Therefore, you should use incognito mode (Ctrl + Shift + N on Chrome) to avoid unwanted price increases. This way, you can see more objective prices and improve your chances of finding cheap flights to Thailand.

Compare prices via trusted apps

You should not check prices on just one airline, as you may miss better options. Use platforms such as Skyscanner, Google Flights, or Kayak to compare fares across multiple airlines and different time slots. This way, you can easily find the cheapest flight day and choose the best price that fits your budget.

Snag tickets0d and Flash Sale

Budget airlines such as Vietjet Air or AirAsia often launch promotional campaigns with tickets0d or very low prices (excluding taxes and fees). Flash Sale periods are usually short and the number of tickets is very limited, so you need to check regularly. If you are ready with your timing and act quickly, you can absolutely snag a flight ticket to Thailand at an extremely low cost.

Prepare high-speed internet

Finding cheap tickets requires very fast action because promotional tickets are usually limited and sell out quickly. Even a few seconds of slow or lagging internet can make you lose the chance to buy a good fare. Therefore, make sure you have a stable, high-speed internet connection so searching and payment go quickly, increasing your chances of success.

How far in advance should you book flights to Thailand?

To get the best flight prices to Thailand, you should book about 1 to 3 months in advance. This is the time when you can more easily choose flight times that suit your needs and budget. Booking early also helps you be more proactive with your travel plans and itinerary.

For trips during peak season (from month 11 to month 2 next year), you should book even earlier, about 4 to 5 months in advance, to have more good options. This helps limit the chance of rising fares or sold-out seats on prime flight times. If you book too close to departure, ticket prices can rise sharply, even 2-3 times higher than normal.

Latest flight prices to Thailand for holidays and Tet

During peak periods such as Lunar New Year, Songkran Festival (month 4), or the holiday period 30/4- 1/5, flight prices to Thailand usually rise sharply due to increased travel demand. This is also when many people book tickets, so flights sell out quickly. According to the system SimPM, round-trip fares during this period may be around8.000.000d -10.000.000d, even higher if booked close to the departure date.

To avoid sold-out flights and high prices, you should follow the holiday schedule and book as soon as the airline opens sales. The earlier you book, the more options you’ll have in terms of flight times and better fares. This also makes it easier to arrange a more suitable itinerary.
