Arriving at Ubon Ratchathani Airport
There two sky-bridges at Ubon Ratchathani Airport, but they don't appear to be used at all for domestic flights, which is all there are these days. You will use stairs to exit the plane and walk to the terminal building. You will enter the terminal directly into the baggage claim area. There is only one baggage belt.
Once you get your bags, you can exit the arrivals hall. Outside baggage claim, you'll find a couple of car rental counters and taxi counters for transfers to Ubon Ratchathani city or other destinations, such as the bus station or the Lao border.
