Recent Traveller Feedback
Security at Suvarnabhumi Airport follows the standard international 100 ml liquid rule for carry on bags, so I kept all my toiletries in a clear plastic bag and went through the checkpoint with no issues. There is no liquid limit for checked bags of course, and I packed all my bigger bottles in the suitcase without any problems at all.
Traveled with our baby on a flight from Bangkok to Phuket and gate checked the stroller for free right before boarding, and it was waiting for us right at the aircraft door after landing. The infant ticket also came with a checked baggage allowance which was helpful for all the baby gear and supplies we needed to bring along.
I have flown Thai Airways many times around Southeast Asia and they almost never weigh carry on bags at the gate as long as they look reasonable. The official limit is 7 kg for the cabin bag plus one small personal item, and enforcement at BKK is usually pretty relaxed unless your bag looks obviously overstuffed or too big for the overhead bin.

Frequently Asked Questions
Does Thai Airways economy class include one or two checked bags?
Thai Airways standard economy fares like Saver and Standard include one checked bag weighing up to 23 kg or 50 pounds under the piece concept system, while the more flexible Flex and Full Flex economy fares include two checked bags instead.
Each checked bag on Thai Airways must stay within 158 cm or 62 inches when you add the length plus width plus height together, and this linear size rule applies the same way for all cabin classes including economy and business.
The cheapest Saver fares on some regional routes to countries like Cambodia, Laos, Myanmar and Vietnam include no free checked baggage at all, so you should always check the exact allowance for your specific route and fare before you travel.
What are the carry on size and weight limits on Thai Airways?
Thai Airways allows one carry on bag per passenger in economy class with a maximum weight of 7 kg or about 15.4 pounds and maximum dimensions of 56 x 45 x 25 cm which equals 22 x 18 x 10 inches including wheels, handles and side pockets.
The 56 cm height limit is slightly taller than the standard 55 cm used by many other airlines, so most standard rolling carry on suitcases will fit without problems in the overhead bins on Thai Airways widebody aircraft.
Passengers also get one small personal item in addition to the main cabin bag, and this personal item has to fit completely under the seat in front of you on the aircraft.
How much checked baggage does Thai Royal Silk Business Class include?
Thai Airways Royal Silk Business Class passengers receive two free checked bags each weighing up to 32 kg or 70 pounds, which is one more bag and 9 kg heavier per piece compared with the standard economy allowance of one 23 kg bag.
Royal Silk passengers also get the same carry on allowance as economy with one 7 kg cabin bag plus one personal item, so the main difference between business and economy on Thai Airways is the much more generous checked baggage allowance.
The Royal Silk Class name is the official Thai Airways brand for their business class cabin, and it comes with many other benefits like priority boarding, lounge access and a premium meal service on board in addition to the extra baggage.
Does Thai Airways have a separate personal item allowance on top of the carry on?
Yes, every Thai Airways passenger is allowed one small personal item on top of their regular carry on bag, and common examples include a handbag, small backpack, laptop bag or briefcase that can fit easily under the seat in front.
Thai Airways does not publish a strict separate size or weight limit for the personal item on their website, but it should be reasonably small and clearly different from a second full size carry on bag to avoid problems at boarding.
This is different from airlines like Emirates or Oman Air that do not include any separate personal item allowance in economy class at all, so on Thai Airways you always have space for the essentials you want to keep close at hand.
What is the maximum weight per checked bag in Thai economy versus Royal First Class?
In Thai Airways economy class each checked bag can weigh a maximum of 23 kg or 50 pounds, while in Royal Silk Business Class and Royal First Class the per bag weight limit increases to 32 kg or 70 pounds for heavier luggage or denser packed items.
Royal First Class passengers also receive three free checked bags in total, which is the most generous allowance on Thai Airways and gives you plenty of space for longer trips or when traveling with multiple sets of clothing and equipment.
Any bag that exceeds the weight limit for your cabin class will be charged an excess weight fee at the airport, so it is always a good idea to weigh your bags at home before you leave to avoid unexpected extra charges.
