Direct Flights vs Connecting Flights
Direct Flights
Currently, there are no direct flights between Dublin and Thailand. Travelers must book flights with at least one connection.
Connecting Flights
The most efficient and affordable option is booking a flight with a single layover. Airlines such as Emirates, Qatar Airways, and Etihad Airways often provide competitive fares with stopovers in Dubai, Doha, or Abu Dhabi.

The Best Time to Fly from Dublin for Budget Travelers
Flight prices between Europe and Thailand depend heavily on seasonal demand. Choosing the right travel dates can significantly reduce the cost of your trip.
The Cool Season (November to February)
This is Thailand’s peak tourist season with comfortable temperatures between 22°C and 30°C and minimal rainfall.
Because many Europeans travel to Thailand during winter holidays, flights from Dublin become significantly more expensive during this period.
If you plan to visit during Christmas or New Year, it is recommended to book several months in advance. See our guide on How Far in Advance to Book Flights to Thailand.
The Rainy Season (June to October)
The monsoon season often offers the cheapest flights from Europe. Short rain showers are common, but they rarely last the entire day.
Hotels and tours may also be discounted by 40–60% compared with peak season prices.

2026 Entry Requirements for Irish Citizens

The Thailand Digital Arrival Card (TDAC)
Thailand has replaced the traditional paper arrival card with a digital system. Travelers must submit the Thailand Digital Arrival Card online within 72 hours before arrival.
Expert Tips to Save Money on Flights
- Be flexible with travel dates. Flights departing midweek are often cheaper than weekend flights.
- Use comparison tools. Platforms like Skyscanner allow you to compare prices across an entire month.
- Consider one-way tickets. Sometimes two one-way tickets are cheaper than round-trip fares. See One Way vs Round Trip to Thailand.
- Track prices early. Start monitoring flight fares several months before departure.
Travel Costs and Budgeting for Your Trip
Once you arrive in Thailand, travel costs are significantly lower than in Ireland.
Budget travelers can explore the country on approximately $30–$50 per day (around €28–€45) by staying in hostels and eating street food.
Travelers preferring mid-range hotels and additional comfort may spend around $80–$150 per day.
