Bangkok to Siem Reap: Bus or Flight?

Bangkok to Siem Reap is the main gateway to Angkor Wat. Important: the Thailand to Cambodia land border has been closed to travelers since 2025 amid a border dispute, so the direct buses via Poipet are suspended and flying is currently the only way across. Check the latest status before you plan. When the crossing reopens, the direct bus is the cheap, simple option that handles the Poipet border for you. Here is how the options compare.
