The usual hand luggage allowance on international Thai Smile flights is 1 cabin bag and a small personal item such as a handbag or camera case. However, this can vary based on a range of factors, including the cabin class you’re in and type of aircraft. In economy, each carry-on bag cannot be heavier than 15lbs or be larger than 22in x 17in x 9in. For the most relevant advice, consult your
Thai Smile plane ticket.
