Stop 01 · The frame
A cabin frame rarely asks about the shell alone. The sizer at the gate reads the bag as packed and extended — casters on the ground, handle out, nothing tucked away. The tape that governs is the one printed by the airline on your fare.
Two numbers decide the same bag on the same day: the frame published by the carrier that sold the ticket, and the frame of whichever operator actually flies the leg. Where they disagree, the gate follows the leg’s own tape.
At home, honesty is cheap. Measure the bag loaded, extended and closed the way the fare’s line reads — and write the number down before the suitcase closes.
The frame as the sizer sees it — handle out, wheels down.
Stop 02 · The scale
Full-service cabins commonly publish one ceiling for everyone. Low-cost fares split into tiers, and on the lightest ones the overhead bin is not part of the deal at all — the seat in front of you is.
Published ceilings vary by airline and by fare, and the counter scale is the one that bills. The guide holds each carrier’s current figures — check the fare you booked, not the one beside it.
Stop 03 · The tray
Screening practice belongs to the airport, not the airline — but what it pulls from your bag can matter more than a centimetre of frame.
No bottle above 100 ml, and every one of them inside the same clear litre pouch. What counts is the container’s printed size, not the amount still sloshing in it.
Spare lithium stays in the cabin for the whole trip — never in a bag that goes below. A unit of 160 Wh or less boards after the airline says yes, and two pieces per traveller is the usual cap.
Anything with a working edge rides in the hold on most routes. When a pocket knife’s fate is unclear, the hold is the answer that never argues.
One trip · The story
Nadia Rahman and Imran Osman flew from Changi to Denpasar for their honeymoon week — one cabin bag each, both zipped flat. Outbound, nothing was measured twice: two spinners into the overhead bins, the morning flight quiet, the bins closed without comment.
Bali was the generous direction. In Ubud they bought two carved panels and a stack of woven runners, and the bag that had left Singapore flat had one feature they only remembered at the airport: an expansion zip running its full length.
At the sizer near the gate, the bag measured the way the airline measures it — zipped open — at 61 centimetres, five past the frame on that fare. Not heavy, not oversized in the way people fear: simply longer, and the extension had added every one of those centimetres. The tag went on, a gate fee followed, and the woven runners rode home in the hold.
On the fare I booked, those five centimetres were never allowed.
— Nadia, at the gate in Denpasar
The return had its own quiet lesson, printed all along: the frame belonged to the fare. Back in Singapore, both of them read the next booking against the guide first — the frame, the fare, the extension — before anyone touched a zipper.
Interchange · Two rules meet
A single itinerary can put two operators under one route, and each brings its own frame, its own scale and its own gate. The fare you bought speaks for the carrier that sold it — not always for the crew at the second gate.
Its frame covers the first flight, and its fines print on your booking. This is the tape most travellers measure against — and the one that can change at the connection.
A regional or partner operator measures by its own numbers, wheels included where it says so. Where the two disagree, the gate that lifts the bag has the deciding tape.

Questions
The guide was built around twenty UK carriers first and reaches well beyond them — and the same names fly the routes out of Changi every day. Start with the airline on your booking, then look up whichever operator is actually flying each leg.
Nothing. The guide is free reading and this page adds no fee, no form and no sign-up to it — you look, you measure, you pack differently.
Where the fare says the bag is read extended, the wheels and handle sit inside the number — so measure the same way at home, or let the sizer run that check for you at the gate.
It has to. Whatever their size, cells and power banks stay out of checked and gate-checked bags; anything up to 160 Wh boards once the airline agrees, and two pieces per traveller is the normal ceiling.

Important information
This page is a paid placement, commissioned and paid for by CabinReady. Everything it asserts about the guide is the publisher’s own claim, not independent reporting.
Allowances and fees belong to each airline and shift with the season. Nothing here is advice of any kind, and the staff at the desk and the officers at the tray outrank it every time.
This page collects nothing and keeps nothing. Anything you read on the guide’s own site answers to that site’s notices; the rest of the detail lives in the privacy page.
Reading on accepts the terms of use. The guide keeps its own conditions separately, and they are its own affair.
