Your boarding pass and travel ID will need to be presented to security personnel.

They won't be allowed on board and will be confiscated. __Flights to Sum Sao information__ | Destination airport | Udon Thani Intl. | | ----------------------------- | ---------------- | | Destination airport IATA code | UTH | | Destination city name | Udon Thani | | Roundtrip price | CA $133 | ## Explore a world of travel with Expedia -
