Match your bag to the airline, before the bin decides.

Frames, kilos and tray rules for the carriers leaving Singapore — read against the fare you actually booked, with the size guide doing the looking-up.

Frame, kilos and tray — read against the fare’s own line.

Stop 01 · The frame

What the sizer measures — and when.

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.

Stop 02 · The scale

Kilos by fare, not by habit.

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.

Full-service fare
7 kg · one piece
Selected fares
10 kg · overhead included
Lightest fares
underseat only

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

Three questions the tray settles.

Screening practice belongs to the airport, not the airline — but what it pulls from your bag can matter more than a centimetre of frame.

01

Liquids, gels, aerosols

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.

02

Cells and power banks

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.

Cabin only
03

Tools and blades

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

The bag that outgrew its own zipper.

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.

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

One booking, two tape measures.

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.

LEG 1

The ticketed carrier

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.

LEG 2

The partner at the second gate

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

Asked at the counter, answered here.

Q1Which airlines does the guide cover?

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.

Q2Does a size check cost anything?

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.

Q3Are casters and handles measured too?

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.

Q4Can a power bank fly in the cabin?

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.

Q5Who publishes this page?

CabinReady, a London-based publisher, places the page as paid promotional material. Write to [email protected] with anything it leaves unclear; the phone line is +46 525-240 00.

Q6Is this the guide itself?

No — this page frames the questions. The sizes live on the guide’s own pages at cabinready.co.uk, one airline at a time.
