Cabin frames, weight ceilings and counter fees for the carriers flying out of Thailand — in plain figures, alongside the screening items that tend to stop at the line.
The frame · the kilos · the second piece · the counter fee

Three checkpoints decide a bag’s fate — the sizer at the gate, the seat space, the scale at the counter — and no two of them read the same line.
Read by the sizer beside the gate — wheels and handles in the count wherever the operator measures the bag extended.
Overrun: a counter fee, and the bag flies below.
Checked at the seat space as you board — a laptop sleeve or a handbag, not a second suitcase in miniature.
Overrun: it merges into the cabin bag, or goes below.
Weighed at the counter — the scale that decides whether the shopping rides free.
Overrun: excess-weight charges, paid at the desk.
Weighed at home — the cheapest moment to find the number out.
The ceilings above are the usual published figures on routes flown from Thailand. Operators set their own, and the fare decides what is included — the checker holds each airline’s current numbers. Confirm yours before the packing starts.
A single booking can seat two operators under one route, and the tape doing the measuring belongs to the carrier flying that leg.
A regional partner on the second flight brings its own tape; its centimetres and its kilos apply, not the ones printed at booking. The allowance you were sold follows the ticket’s carrier, not always the crew waiting at your gate.
Many frames read the bag at full extension, casters to the floor and handle pulled. A case that stands inside the lines can roll past them the moment the cage measures it moving.
The direction home carries the shopping. Whatever flew out weighing nothing tends to come back weighing something — and the return fare has its own ceiling.
Check the operators on the return leg before departure. The souvenir still fits a bag that has not been zipped yet.
The useful place to read a limit is at home — with the bag still open.
Mali Suwannarat and her brother Krit spent the first weekend of the month in Chiang Mai, and flew back to Bangkok on the Sunday evening — one cabin bag each, and a laptop sleeve between them. On the way up, nothing was checked twice: two bags into the overhead bins, the sleeve under the seat, the sizer never came out.
The way home was the heavier direction. At the Sunday market by Tha Phae Gate, Mali bought a khantoke set — a lacquered tray with six small bowls, boxed, padded and honest about its size. It left the market in its own carry box with a woven handle, small enough to sit on a lap.
At the airport, the agent at the counter counted three pieces: the bag, the sleeve, the box. The fare allows two. The box was not oversized and it was not heavy — it was simply one piece too many, and the fee for the extra went onto a card before the bags moved on.
The sizer never came out. It was never the centimetres — it was the count.
The next trip started the other way round: both allowances read at home, every piece — bag, sleeve, box — listed against the fare in the checker at carryonsize.com, before anything left the house. At the counter, there was nothing left to count.
Screening answers to the airport’s own security rules, not to the airline’s rulebook — and it asks about things the frame never mentions.
Spare cells and power banks belong in the cabin — never in luggage that heads below, however short the hop. Anything from 100 up to 160 Wh needs the airline’s nod before it flies, and two units per traveller is the usual cap.
Containers up to 100 ml each, together inside one clear litre bag, out of the cabin bag and into the tray.
Large electronics come out of the bag and take their own pass through the scanner — the sleeve is where they go back.
Passport, boarding pass and wallet stay on you. The tray is the last place you want to be retrieving them from.
Airline, fare, bag — put the three in and read the answer. Free, no sign-in, and the figures are kept current.

A list well over a hundred long, Thai carriers included — the full-service names out of Suvarnabhumi, the low-cost fleets of Don Mueang, and the international operators flying the same routes. Figures are refreshed as allowances change.
No, and there is nothing to sign up for. Choose the airline, key in the numbers, read the verdict. A free reference, not a shop.
With the operators whose frames read the bag extended, yes. Measure the same way at home — casters on the floor, handle pulled — or the sizer will do the measuring for you at the gate.
Not in a checked or gate-checked bag, no — spare lithium stays in the cabin whatever the weight. A unit of up to 160 Wh may fly once the airline consents, and carriers usually draw the line at two per person.
