Are there lockers at the airport where you can leave your bags. On one of their websites they mention a Left Baggage Counter where you can leave your bags for a fee.

so why waste time to ask then? Its pretty clear to anyone ever been to LoS; there are NO luggage lockers wherever in this Kingdom. its all manual.

Left baggage service counter is provided in the departure hall on the 2nd floor of Domestic Terminal with the service fee as the followings :

75 Baht/piece for baggage left not over 24 hours.

The additional fee of 35 Baht/piece/12 hours to be charged for baggage left over 24 hours. For more details, please call 0-2535-1882.

I wouldn't leave anything of any value in there, even batteries or a cigarette lighter, and ensure the bag is locked. These two measures will prevent an opportunistic thief but not a determined one.
