Indian Airlines Cabin Baggage Rules: Every Carrier Compared

Indian Airlines Cabin Baggage Rules: Every Carrier Compared

On paper, Indian cabin luggage rules look identical across every airline: one bag, 7 kg, one personal item. In practice, the details differ just enough to catch you out — a laptop bag that’s free on IndiGo but counts against your limit on SpiceJet, a hard-shell that clears the size at a small airport and gets flagged on the return at Delhi, an excess counter that charges ₹700 a kilo when the airline next to it charges ₹550. Since 2024, enforcement has gone from lax to relentless, and the gap between knowing the rules and guessing at them is now measured in real money at the gate.

This guide compares the cabin luggage rules of every major Indian carrier — IndiGo, Air India, Akasa Air, SpiceJet, Air India Express, and Alliance Air — side by side. It covers the one national rule they all follow, the dimensions and weights that differ, the personal-item catch that trips up the most travellers, and the enforcement reality at the gate. The goal is a single reference so you never have to check three airline websites before a trip again.

The short answer: Every Indian airline allows one cabin bag (7 kg economy, 8 kg on Air India) plus one personal item, under a 55 × 35 × 25 cm box (55 × 40 × 20 cm on Air India). The real difference is the personal item — IndiGo, Air India, and Akasa give you a separate 3 kg for it, while SpiceJet counts your laptop bag inside the 7 kg. Air India is the most generous; SpiceJet is the strictest on effective space and the priciest on excess.

KEY TAKEAWAYS

• Since the BCAS rule of May 2024 (fully enforced by December 2024), every Indian carrier allows just one cabin bag (7 kg economy) plus one personal item — the old two-bag allowance is gone.
• Cabin dimensions are near-standard: IndiGo, SpiceJet, Akasa, and Alliance Air use 55 × 35 × 25 cm; Air India and Air India Express use the slightly wider 55 × 40 × 20 cm.
• The real difference is the personal item: IndiGo, Air India, and Akasa give a separate 3 kg personal item; SpiceJet counts your laptop bag within 7 kg.
• Air India is the most generous (8 kg cabin, biggest box); SpiceJet is the strictest on effective capacity and charges the most excess (~₹700/kg vs IndiGo’s ~₹550).
• Enforcement is now three-point at metros — kerb, counter, and gate — and the sizer measures wheels and handles; a hard 56 cm bag fails where a soft one might flex through.
• Power banks must travel in the cabin (DGCA advisory); cabin liquids follow the 100 ml rule.
• Most cabin-friendly: Air India. Buy a bag at or under 55 cm and 7 kg to clear every carrier.

1. The One Rule Behind Every Indian Cabin Policy: BCAS

Before the differences, the constant. Every Indian airline’s cabin policy sits on top of a single national rule set by the Bureau of Civil Aviation Security (BCAS). For tickets booked after 2 May 2024, the old two-cabin-bag allowance was replaced with a strict one cabin bag plus one personal item rule, with the cabin bag capped at 7 kg for economy. Enforcement rolled out fully by December 2024, and by 2026 it is effectively universal — the “second cabin bag” travellers used to slip through is gone.

Two more national rules apply everywhere. Power banks and spare lithium batteries must be carried in the cabin, never in checked baggage — reinforced by a DGCA advisory in late 2025. And cabin liquids follow the universal 100 ml-per-container rule, packed in a single one-litre clear bag; liquids over 100 ml are among the most common reasons bags get pulled at screening. A tiny share of tickets booked before May 2024 still qualify for the older two-bag allowance under a grandfather clause, but in practice almost every flyer today falls under the one-bag regime.

FUN FACT: Here's a quirk of enforcement: a hard-shell suitcase is judged more strictly than a soft- one, because it can’t compress. A rigid 56 × 36 × 26 cm case will be rejected at the sizer even though the difference from the limit is marginal, while a soft bag of the same stated size often flexes through because the fabric gives. If you fly IndiGo or Akasa often, a soft cabin bag built to 55 × 35 × 25 cm is quietly the safer buy than a hard case cut a centimetre too large.

2. Every Carrier Compared: The Cabin Baggage Table

Here is the whole field at a glance. Every carrier follows the BCAS one-bag rule, so the columns that matter are the cabin weight, the exact size box, whether the personal item is separate or counted in, and what excess costs at the airport if your bag is over.

Figures are for domestic economy and can change by fare, route, and aircraft; excess rates vary and are far cheaper pre-booked online. Confirm on the airline’s site before you fly.

3. The Personal Item: Where Carriers Actually Differ

If there is one line in the whole comparison worth memorising, it’s this. The 7 kg cabin bag is near-universal — but what you can carry in addition to it is where the airlines split. IndiGo, Air India, and Akasa Air give you a separate personal item of up to 3 kg — a laptop bag, handbag, or small backpack that fits under the seat — on top of the 7 kg. That effectively gives you around 10 kg of total carry-on.

SpiceJet is the exception, and it catches people out constantly: it counts the personal item within the 7 kg total. So the same laptop bag that rides free on IndiGo eats into your cabin allowance on SpiceJet, leaving noticeably less for the trolley. If you carry a heavy laptop and a work bag, that difference can be two or three kilograms of usable space — enough to decide whether your main bag clears the scale. It’s the single most important distinction in Indian cabin rules, and the one least visible until you’re at the counter.

4. Enforcement & Excess: What Happens at the Gate

Knowing the rules only helps if you also know how they’re enforced — and in 2026 that has changed sharply. At the big metro airports (Delhi, Mumbai, Bengaluru, Hyderabad), cabin bags are now weighed at up to three points: the kerb, the check-in counter, and again at the boarding gate on busy departures. The sizing cage measures the longest, widest, and tallest points of the bag, including wheels, handles, and outer pockets. An over-limit bag is gate-checked into the hold, with excess charged — and excess rates differ by carrier: roughly ₹550/kg on IndiGo, ₹600/kg on Air India, and ₹700/kg on SpiceJet at the airport, with pre-booked online rates far lower.

THE REAL PICTURE: The counterintuitive part: dimension failures now cost travellers more than being overweight. Industry data puts the average rebooked-check-in cost from an oversized cabin bag at around ₹650, higher than the average overweight charge of about ₹500 — and a bag that cleared a Tier-2 airport on the way out can be flagged on the return when a different ground crew runs the trim. There’s no appeal at the gate. The only reliable fix is to buy a bag built at or under 55 × 35 × 25 cm (which clears every carrier), weigh it packed at home, and treat the 7 kg limit as a ceiling, not a target. Measure before you buy, not after.

5. How to Never Get Caught at the Gate

• Buy at or under 55 × 35 × 25 cm: this box clears every Indian carrier, including the strict LCCs. Measure the bag including wheels and handles, not just the body.

• Weigh it packed at home: treat 7 kg as a ceiling. Airport scales can read 200–500 g heavier than yours, so aim for around 6.5 kg.

• Remember SpiceJet counts your personal item: on SpiceJet, your laptop bag is inside the 7 kg — pack the trolley lighter to compensate.

• Pre-book any excess online: it’s far cheaper than the counter, where rates run ₹550–₹700/kg depending on the airline.

• Prefer soft-sided for a tight fit: a soft cabin bag flexes through the sizer where a rigid one won’t, if you’re right at the limit.

• Keep power banks and valuables in the cabin: power banks are barred from checked bags, and a gate-checked cabin bag shouldn’t hold your laptop, documents, or medication.

6. Verdict

Indian Cabin Luggage rules are more uniform than they’ve ever been — one bag, 7 kg, one personal item, under a 55 cm box — but the small print still decides whether you sail through or pay at the gate. Air India is the most generous, with an 8 kg bag, the widest size box, and a separate personal item. IndiGo and Akasa match the 7 kg-plus-separate-item template and enforce it consistently. SpiceJet is the outlier to plan around, because it folds your personal item into the 7 kg and charges the most for excess.

The bigger shift is enforcement: three-point weighing at the metros, strict sizes that count wheels and handles, and dimension failures that now cost more than being overweight. None of it is a problem if you prepare. Buy a bag built to 55 × 35 × 25 cm, weigh it packed, keep a slim personal item, and remember which airline counts what. Do that, and every Indian carrier’s cabin rules become a formality rather than a fee.
