Why Chiang Mai?

Tips for Finding Better Domestic Flight Deals

Friendly reminders that help stretch the travel budget:

• Book flights early during popular seasons
• Check both Bangkok airports for flexibility
• Consider shoulder months for fewer crowds
• Watch out for flash sales from low-cost airlines.
• Add baggage allowance during booking; it's cheaper than at the airport.
• Select seats only if truly needed (saving extra baht)

The goal is always the same: spend less on getting there and more on loving the trip once you arrive.

Why Domestic Flights Make Thailand Easier to Explore

Thailand’s geography is diverse, with mountains in the north, tropical islands in the south, modern city life in Bangkok, and historical towns in between. Domestic routes keep travel quick and simple, allowing more time to enjoy each stop.

Whether visitors plan:

• Trekking in Chiang Mai
• Snorkelling in Phuket
• Island-hopping from Krabi
• Cultural experiences in Ayutthaya

There’s always a flight ready to take them there faster than any bus or overnight train.
