Expert Insight
Bangkok operates two airports to split airline traffic. Suvarnabhumi (BKK) was built to handle long haul international demand and premium carriers, while Don Mueang (DMK) was later repositioned to support low cost and regional airlines.
This separation helps reduce congestion and allows airlines to operate more efficiently based on their business model.
For travelers, the key is not which airport is better overall, but which airport matches the airline you are flying with.
