Thai Airways Carry-On Size

Thai Airways has moderate enforcement — limits are real but not always checked. That said, oversized bags risk being gate-checked, especially on full flights. Use packing cubes to stay organized and compressible, and check our what not to pack guide to avoid wasting space on items you will not need.

For clothing that packs small and performs well in transit, see our travel fabrics guide and our merino t-shirt roundup — merino compresses better than cotton and handles multi-day wear between washes.
