There is no single cabin bag size accepted by every airline in India. Air India lists 55 × 40 × 20 cm, while IndiGo lists 55 × 35 × 25 cm. These limits are different, even though both add up to 115 cm.
Yes, airlines can check your cabin bag’s size and weight. A suitcase may be inspected at check-in or boarding, and a bag labelled “cabin approved” can still exceed your airline’s limits. Measure the fully packed bag, including wheels, fixed handles and outer pockets, before travelling.
This guide compares airline dimensions, explains the 7 kg rule, and helps you decide whether a 20-inch, 22-inch or 24-inch suitcase belongs in the cabin or checked baggage.
Airline policies checked: 19 October 2026. Confirm your operating airline’s current allowance before departure.

What Is the Maximum Cabin Bag Size in India?
The maximum depends on the operating airline and sometimes the aircraft. Check all three measurements rather than relying on a general “115 cm” description.
| Airline / aircraft | Published main cabin-bag dimensions | Standard weight allowance |
|---|---|---|
| Air India | 55 × 40 × 20 cm | 7 kg in Economy and Premium Economy; 10 kg in Business and First. |
| IndiGo | 55 × 35 × 25 cm | One main cabin bag up to 7 kg. |
| Air India Express | 56 × 36 × 23 cm | Standard 7 kg combined allowance for the cabin bag and personal item. |
| SpiceJet — Boeing | 55 × 35 × 25 cm | 7 kg combined, including an additional permitted laptop bag or purse. |
| SpiceJet — Q400 | 50 × 35 × 23 cm | 7 kg combined, including an additional permitted laptop bag or purse. |
| Akasa Air | Its published allowance table specifies 115 cm total: length + width + height. | One hand bag up to 7 kg. Confirm any additional size conditions before buying a bag. |
Official sources: Air India, IndiGo, Air India Express, SpiceJet and Akasa Air.
These are standard allowances, not a substitute for the conditions of a purchased upgrade, special arrangement or partner-operated flight.
Why 115 cm Does Not Mean Any Shape Is Acceptable
A bag measuring 55 × 40 × 20 cm totals 115 cm. So does a bag measuring 55 × 35 × 25 cm. However, the first is wider and the second is deeper.
Where an airline specifies individual dimensions, meeting the combined total does not cancel those limits. A long, narrow bag can also total 115 cm while being too long for permitted cabin storage.
Buying one bag for several airlines? Compare the smallest permitted measurement in each direction across your planned flights. For example, 55 × 35 × 20 cm falls within the published main-bag dimensions of Air India, IndiGo, Air India Express and SpiceJet Boeing services. It is still too tall for SpiceJet’s listed Q400 limit.
Do Airlines Check Cabin Bag Size in India?
Yes. Airlines can check dimensions as well as weight. Staff may ask you to place the bag in a baggage sizer, measure it or have it weighed. Checks can happen at the check-in counter or boarding gate.
Not every bag is necessarily measured on every departure. That does not make an oversized bag compliant, and a previous flight without a check is not proof that the bag will be accepted again.
Does Air India Check Cabin Bag Size?
Air India publishes size limits, so prepare for them to be enforced. A trolley that meets the weight allowance can still exceed the permitted dimensions. Online check-in does not exempt your luggage from inspection.
Does IndiGo Check Cabin Bag Size?
IndiGo also specifies dimensions and a weight limit. Treat both as requirements. Do not assume a bag will be accepted because it looks similar to other passengers’ luggage or because you have previously used it on another airline.
Three separate checks: a bag can be the correct size but overweight, the correct weight but oversized, or compliant individually while exceeding your permitted number of pieces.
If your bag is just outside the limit, read what happens when a cabin bag is one inch too big.
How Do You Measure a Cabin Bag Correctly?
Measure the bag as you will actually carry it, with the contents packed and all compartments closed.
- Retract the telescopic handle. Include any part that still protrudes when fully retracted.
- Measure the full height. Include wheels and the fixed top handle.
- Measure the widest point. Include side handles and filled side pockets.
- Measure the deepest point. Include front pockets, bulges and any expanded section.
- Compare each measurement. Do not check only the sum of the dimensions.
- Weigh the complete bag. The suitcase itself counts toward the allowance.
For an irregular backpack or duffel, measure the outermost points when packed. Soft sides help only if the bag genuinely fits the permitted space without excessive force.
Check the product listing carefully: some luggage sellers advertise the suitcase body size separately from its overall dimensions. Ask for the external measurements including wheels and handles.
Are 20-Inch, 22-Inch or 24-Inch Bags Allowed?
Inch labels are not reliable airline approvals. They may describe the suitcase body, an approximate product category or its overall height. Width and depth still matter.
| Advertised size | Exact inch-to-centimetre conversion | What it means for cabin travel |
|---|---|---|
| 20 inches | 50.8 cm | May fit many main cabin-bag limits, but check overall height, width and depth. |
| 21 inches | 53.34 cm | May fit a 55 cm height limit if this is the full external height. |
| 22 inches | 55.88 cm | A true external height of 22 inches exceeds a 55 cm limit. |
| 24 inches | 60.96 cm | Exceeds the main-bag height limits listed above; plan to check it in. |
Why a “22-Inch Cabin Bag” Can Be Rejected
A suitcase measuring exactly 22 inches externally is 55.88 cm tall. That is greater than 55 cm, even though some product descriptions round the numbers. If the advertised 22 inches excludes wheels, the actual bag may be taller still.
Likewise, a 22 × 14 × 9-inch bag measures approximately 55.9 × 35.6 × 22.9 cm. Those measurements are not interchangeable with 55 × 40 × 20 cm.
Can You Expand a Cabin Suitcase?
Only if its expanded dimensions still comply. A suitcase may meet the limit with its expansion zipper closed and exceed it when expanded. Recheck after shopping or packing for the return flight.
What Does the 7 kg Cabin-Baggage Limit Include?
Where your allowance is 7 kg, that includes the bag and everything inside it. A light-looking suitcase can be overweight because of a laptop, books, chargers or toiletries.
Example: a trolley weighing 2.8 kg empty leaves 4.2 kg for its contents under a 7 kg allowance. A lighter bag gives you more usable packing weight.
Whether your handbag is included in that same total depends on the airline:
- Air India and IndiGo: publish an additional qualifying personal-item allowance of up to 3 kg.
- Air India Express and SpiceJet: their standard 7 kg allowance covers the main bag and permitted personal item together.
See does a handbag count as carry-on in India? for the detailed comparison.
Separate allowances are not automatically interchangeable. If your policy provides 7 kg for the main bag and 3 kg for a personal item, an 8 kg trolley plus a 2 kg purse does not automatically comply.
Can You Take Two Cabin Bags, a Handbag or a Laptop Bag?
One main cabin bag plus one qualifying personal item is different from two full-size cabin bags. A large backpack does not become a personal item simply because you are also carrying a trolley.
- Trolley plus small purse: may fit a main-bag and personal-item allowance.
- Backpack plus purse: may work if the backpack is your main cabin bag.
- Trolley, backpack and handbag: three separate pieces; do not assume all are included.
- Laptop bag: may use your personal-item allowance rather than provide a further free bag.
Check the permitted dimensions and weight for the smaller item. Fitting under the seat alone is not enough. Our personal-item guide explains common combinations.
What Happens If Your Cabin Bag Is Too Big or Overweight?
The airline may ask you to repack, consolidate your belongings, purchase an available allowance option or check the bag into the hold. A weight upgrade does not automatically permit a larger suitcase.
There is no universal free tolerance for a bag that is slightly over the limit. Resolve a known problem before reaching the gate, where your options and available time may be limited.
Are Gate-Checked Bags Always Charged?
No. A compliant bag taken into the hold because cabin storage is full is a different situation from a bag that exceeds your allowance. Charges depend on the reason, airline policy and your booking.
Ask staff whether a charge applies and where you should collect the bag. See when gate-checked bags are free and when airlines charge.
Before handing over a cabin bag: remove power banks and spare lithium batteries. Keep identification, travel documents, essential medicines, money and valuables with you. Tell staff about any battery-powered equipment that remains inside.
What Is Not Allowed in Cabin Baggage in India?
A correctly sized bag can still contain restricted items. Check its contents separately from its dimensions.
- Knives and certain sharp tools: subject to cabin prohibitions.
- Cricket bats, golf clubs and similar sporting implements: not suitable for hand baggage.
- Liquids, aerosols and gels: generally limited to containers of 100 ml or less within a transparent resealable one-litre bag, with specific exceptions such as necessary medicines and baby food.
- Flammables and other dangerous goods: some are prohibited in both cabin and checked baggage.
- Power banks and spare lithium batteries: cabin carriage only, subject to the airline’s capacity, quantity and condition restrictions.
A partly empty 200 ml bottle is still a 200 ml container. Check the applicable exception before carrying larger essential medical liquids.
Read what is not allowed in hand baggage in India and perfume bottle limits. Air India also publishes an official restricted-items guide.
Cabin Bag Checklist Before You Fly
- Check the operating airline and aircraft-specific allowance for each flight.
- Measure the packed bag’s external height, width and depth.
- Keep expandable sections closed unless the expanded bag complies.
- Weigh the complete bag and check whether personal-item weight is separate or combined.
- Count all separately carried bags, including purses and laptop bags.
- Keep documents, medicines and battery items accessible if the main bag must be checked.
- Save your baggage allowance and any paid upgrade with your booking.
- Reweigh and remeasure before the return journey.
Leave a little packing margin. A bag below the limits gives you room for small additions and reduces disputes over measurement or scale differences. Packing cubes organise belongings but do not reduce their weight.
Frequently Asked Questions
What is the maximum cabin luggage size in India?
There is no universal maximum. Use the airline comparison above and check the operating airline’s policy for each flight, including connections.
What are the new cabin baggage rules in India in 2026?
Do not assume an article labelled “new rules” establishes one size or weight limit for every airline. Check the current policy for your booking. The table above reflects the airline allowances checked for this update.
Is a 20-inch suitcase allowed in the cabin?
It may be, but the inch label alone is insufficient. Measure its overall dimensions, including wheels and handles, and check its packed weight.
Is a 22-inch cabin bag allowed?
Only if its actual external dimensions comply. Exactly 22 inches is 55.88 cm, which exceeds a 55 cm limit. Do not rely on rounded product descriptions.
Can a 24-inch suitcase fit in the cabin?
A suitcase with an external height of 24 inches exceeds the listed cabin limits. Plan to check it in, regardless of whether it might physically fit in an overhead bin.
Can I take two cabin bags on Air India?
The standard allowance is one main cabin bag plus one qualifying small personal item, not two full-size cabin suitcases.
Can I carry two bags totalling 30 kg on IndiGo?
A 30 kg allowance concerns checked baggage, not permission to take two heavy bags into the cabin. Whether you can split it across two checked bags depends on your route, booking and applicable piece charges.
What if my cabin bag weighs more than 7 kg?
If your allowance is 7 kg, arrange an available baggage option or repack within the rules. Do not assume that a small excess will be overlooked.
Does a light bag have to meet the size limit?
Yes. Size and weight are separate requirements. An oversized suitcase does not become acceptable merely because it weighs less than the allowance.
