Cabin Bag Size Limit in India: The 2026 Guide to Carry-On Rules

Nothing ruins the start of a trip like being pulled aside at the boarding gate and told your carry-on is going into the hold. It happens more often in India than most travellers expect, and almost always for the same reason: the bag was measured by its shell, not by its true outer dimensions.

Here is what you actually need to know before you fly.

The short answer

For most Indian domestic carriers, one cabin bag up to 55 × 35 × 25 cm and 7 kg, plus one personal item under 3 kg that fits beneath the seat in front of you.

Cabin baggage limits by airline

Airlines revise these policies without much notice, and fare class can change your allowance. Always confirm on your carrier's own baggage page before you travel - treat the table above as a starting point, not gospel.

The mistake almost everyone makes

Airlines measure the outermost points of the bag. That includes the wheels, the retracted telescopic handle, the side grab handles and any external pockets.

This matters more than it sounds. A suitcase advertised as a "55 cm cabin bag" is often 55 cm for the shell alone. Add 4 cm of wheel and 2 cm of handle housing and you are standing at the sizer with a 61 cm bag and a problem.

Before you buy any carry-on, and before you fly with one you already own, do this:

1. Stand the bag upright on a flat floor, handle fully retracted.
2. Measure floor to the highest point of the bag - wheels included, handle included.
3. Measure the widest point and the deepest point, including pockets.
4. Compare all three numbers to your airline's limit.

Hard-shell bags get scrutinised more

A soft-sided bag that is a centimetre over will usually squash into the sizer. A hard-shell case will not. If you fly with a polypropylene or polycarbonate suitcase, you need it to be genuinely within limits rather than nearly within them.

That is the trade-off. Hard shells protect your belongings far better and hold their shape across hundreds of trips - but they give you no margin at the gate.

Weight is enforced separately from size

Meeting the size limit does not get you past the scale. Gate weighing is now routine at Delhi, Mumbai, Bengaluru and Hyderabad. Your laptop counts towards the total whether it sits in your cabin bag or your personal item.

This is where a lightweight shell earns its keep. Every 500 g the empty suitcase saves is 500 g you can actually pack. It is the single most underrated spec on a carry-on.

One bag plus one personal item

Indian airports enforce the one-bag rule strictly. One cabin bag in the overhead bin, one personal item under the seat. A second tote will not get through.

Choosing a cabin bag that clears the gate

If you want one bag that works across carriers without a second thought, aim for something at or under 55 × 35 × 20 cm measured externally. That footprint clears IndiGo's sizer and fits Air India's shallower 20 cm depth limit at the same time.

Beyond dimensions, look for a shell that is light before you pack it, 360° spinner wheels so you are not dragging weight through a terminal, and a TSA lock if any leg of your trip touches the United States.

MYKASE builds its cabin trolley bags around the 55 cm standard in 100% virgin polypropylene, with 8 spinner wheels, TSA lock and a 3-year warranty. Measure yours including wheels and handle before your first flight so you know exactly where you stand at the sizer.

Travelling for longer?

If you are checking a bag anyway, a matched set is usually better value than buying pieces separately. A Set of 2 covers a cabin bag plus a 65 cm check-in; a Set of 3 adds a 75 cm large for family trips and long hauls. Both are available in the Oxford Series and the Miami Series.

Keep exploring: compare 55cm, 65cm and 75cm trolley sizes, or read the hard-shell material comparison before choosing your luggage.
