Where to store bags during layovers, day trips, or while checking out — airports, stations, and the city.
Suvarnabhumi and Don Mueang both have luggage storage — arrival and departure levels; typically 100–200 THB per bag per day.
Hua Lamphong and Bang Sue Grand Station (train) have storage; Southern and Northern bus terminals also offer storage.
Selected BTS stations have small locker banks — limited capacity and size; check at the station office.
Most hotels hold bags for guests before check-in and after check-out, free of charge — just ask at the front desk.
Bounce, Stasher, and Radical Storage operate partner locations in Bangkok (cafes, hotels) — book online; typically 100–150 THB/day.
Photograph your bag before dropping it off and use a TSA-approved lock where possible — most storage services are reliable, but this is standard good practice anywhere.
For a short layover, airport storage is usually simplest since it avoids extra transit time; for longer layovers, a city-based service near the sights you want to see saves the return trip to the airport.
