What Are the Baggage Restrictions on Domestic Flights in Thailand?
Baggage allowances on domestic flights vary by airline and ticket class. Budget carriers typically include only carry-on baggage, while full-service airlines include checked luggage in most fares.
Thai Airways and Bangkok Airways generally include 20-30 kg of checked baggage depending on your ticket class. Budget carriers like Thai AirAsia and Thai Lion Air sell baggage allowance separately, with 15-20 kg typically costing 200-400 THB if purchased in advance.
Carry-on limits are typically 7 kg across all carriers. For flights to Koh Samui via Bangkok Airways, luggage policies are more generous, reflecting the airline's full-service positioning.
The 2025 free domestic flight program for international visitors includes a 20 kg baggage allowance on complimentary flights. When booking domestic connections, verify baggage policies to avoid unexpected fees at the airport.
