Air India Express vs IndiGo vs Akasa Air: Comparing Free Check-In Baggage, Cabin Limits and Excess Rates in 2026
By Diya Verma (Diya Verma covers low-cost-carrier pricing, baggage policy and the hidden add-on fees that decide which Indian airline is actually cheapest.) · Published · 10 min read
The lowest fare on the search results page is rarely the cheapest flight once a single check-in bag enters the picture. This 2026 breakdown of IndiGo, Air India Express and Akasa baggage rules shows where tier-2 flyers actually save money.
Why the cheapest fare is often the most expensive flight
On any metasearch results page, three carriers can sit within a couple of hundred rupees of each other and look interchangeable. The moment you add one piece of checked luggage, that ranking can flip completely. India's low-cost carriers now treat baggage, seat selection and meals as separate revenue lines, so the headline fare you click is only part of the story.
The single most important number to know before you book is the free check-in allowance on your specific fare type. IndiGo, Air India Express and Akasa all sell fare families where the cheapest bucket may include little or no checked baggage on certain routes, while a slightly pricier bucket bundles 15 kg. Comparing the all-in cost, fare plus the baggage you actually need, is the only honest way to rank them.
This guide focuses on domestic India travel as of 2026. International sectors (Gulf, Southeast Asia) follow different and usually more generous rules, and the per-kg excess charge there is steep, so always confirm the allowance for your exact route on the airline's own site before paying.
Free check-in baggage: the headline numbers
For standard domestic fares in 2026, the broad picture is that the legacy-LCC norm of 15 kg free checked baggage still holds for most economy bookings on IndiGo and Akasa Air. Air India Express, now the group's low-cost arm after merging with AIX Connect, generally aligns with a 15 kg domestic checked allowance on its standard fares too, but its lighter value-style fares can carry less, so the allowance is fare-dependent rather than fixed.
Three practical points to remember as of 2026:
- 15 kg is the typical domestic baseline across the three carriers' standard economy fares, but the cheapest fare bucket on a route may offer a reduced or hand-baggage-only allowance.
- Bundled fares (IndiGo's higher tiers, Akasa's flexi-style fares, Air India Express value-plus options) often raise the included allowance to 20 kg or more.
- The allowance is per passenger and usually one piece for domestic; splitting 30 kg across two bags does not always avoid an oversize-piece issue.
Because each airline revises fare families periodically, treat these as indicative and verify the exact kilos shown at checkout for your date and route.
Cabin (hand) baggage limits compared
Cabin baggage is where Indian LCCs have quietly converged, and where gate-side surprises happen most often. The widely applied domestic norm in 2026 is 7 kg of hand baggage in one piece plus a small personal item such as a laptop bag or handbag, with a maximum size around 55 x 35 x 25 cm. IndiGo, Air India Express and Akasa all operate close to this standard.
The friction is rarely the weight on paper, it is enforcement. On full flights, gate staff weigh and gauge cabin bags, and an 8.5 kg carry-on that sailed through one airport can be sent to the hold (with a fee) at another. The personal-item allowance is also not a second full bag: a backpack stuffed to 6 kg will be treated as your cabin piece.
For tier-2 flyers connecting through busy metros, the safe play is to keep the cabin bag genuinely under 7 kg and put anything heavy, power banks excepted, which must stay in the cabin, into checked baggage where the per-kg cost of being slightly over is lower than a gate penalty.
Excess baggage: the per-kg charge that actually decides the winner
Excess baggage is charged per kilogram when you exceed your free allowance, and the rate is what punishes a mis-judged pack. As of 2026, prepaid domestic excess on Indian LCCs typically runs in the broad range of roughly Rs 500 to Rs 750+ per kg depending on airline, route and whether you buy online in advance or at the airport counter. Airport-counter rates are materially higher than prepaid online rates on all three carriers.
The decisive saving is buying an excess-baggage add-on or a higher checked allowance in advance. Pre-purchasing a 5 kg or 10 kg block online is consistently cheaper than paying per-kg at the bag drop, often by a wide margin. If you know you are carrying 22 kg, buying up to a 20 kg or 25 kg allowance at booking beats paying spot excess on 7 kg at the airport.
Because these rates change and vary by sector, never assume, check the live excess price for your route during booking. A flight that wins on base fare can lose decisively once Rs 700-per-kg airport excess on 8 kg is added.
Which carrier wins for the tier-2 flyer?
There is no single winner; the right answer depends on how you pack. If you travel cabin-only, all three are effectively tied and you should simply take the lowest fare, since the 7 kg cabin norm is shared. The baggage policy becomes irrelevant and base fare plus convenient timing wins.
If you check one 15 kg bag, again compare like-for-like: pick whichever carrier's fare that includes 15 kg is cheapest, rather than a rock-bottom fare that secretly excludes checked baggage. This is the most common tier-2 trip and where reading the included-allowance line saves the most.
If you routinely carry 20 kg or more (students moving cities, families visiting home), the winner is whichever airline lets you pre-buy the higher allowance most cheaply. Run the full math on a metasearch tool like FlightGPT that surfaces the real fare, then add the airline's published excess cost before deciding.
Special cases: sports gear, musical instruments and oversize items
Standard allowances assume normal suitcases. Bicycles, golf bags, surfboards and large musical instruments fall under oversize or special-baggage rules and almost always attract a separate fixed handling fee on top of, or instead of, normal excess. These must usually be declared in advance; turning up with a boxed bicycle and no prior booking risks offload on a full flight.
Musical instruments are a frequent pain point. A small instrument within cabin dimensions can ride in the cabin as your hand bag, but a guitar or larger item typically needs either careful checking with fragile handling or, on some carriers, a purchased extra seat (a cabin-seat-baggage option). Policies differ between IndiGo, Air India Express and Akasa, so confirm the exact handling and fee before you fly.
For anything non-standard, including duty-free liquids over cabin limits and large strollers, the rule is the same: read the airline's special-baggage page for 2026 and, where required, pre-book. The fees are real but predictable when arranged ahead, and ruinous when improvised at the gate.
A simple pre-booking checklist to avoid baggage bill shock
Before you confirm any LCC booking in 2026, run this quick check so the fare you pay is the fare you expected. The whole process takes under two minutes and routinely saves more than the difference between competing fares.
- Read the included-allowance line at checkout, not the route average. Confirm whether your fare includes 0, 15 or 20 kg checked.
- Weigh at home. A cheap luggage scale removes the single biggest cause of airport excess charges.
- Pre-buy excess online if you are over the free limit, never at the counter.
- Keep the cabin bag honestly under 7 kg and treat the personal item as small, not a second suitcase.
- Declare special items (sports gear, instruments) in advance.
Do this and the cheapest flight on your screen and the cheapest flight in reality finally become the same booking. When in doubt, the airline's official baggage page is the authority, this guide is indicative and policies are revised through the year.
Frequently asked questions
How much free check-in baggage do IndiGo, Air India Express and Akasa give on domestic flights in 2026?
Standard domestic economy fares on all three commonly include around 15 kg of free checked baggage as of 2026, but the cheapest fare buckets on some routes may offer a reduced or hand-baggage-only allowance. Always confirm the exact kilos shown at checkout for your route and date.
What is the cabin baggage limit on Indian low-cost carriers?
The widely applied domestic norm in 2026 is 7 kg of hand baggage in one piece (around 55x35x25 cm) plus one small personal item such as a laptop bag. IndiGo, Air India Express and Akasa all operate close to this standard and weigh bags at the gate on busy flights.
How much does excess baggage cost per kg on Indian LCCs?
Prepaid domestic excess typically falls in the broad range of roughly Rs 500 to Rs 750+ per kg as of 2026, varying by airline, route and whether you buy online in advance or at the airport. Airport-counter rates are noticeably higher than prepaid online rates, so buy excess in advance.
Is it cheaper to buy extra baggage online or at the airport?
Almost always online and in advance. Pre-purchasing an extra-baggage block at booking is consistently cheaper than paying per-kg spot excess at the bag drop on all three carriers, often by a wide margin.
Which airline is cheapest if I only carry cabin baggage?
For cabin-only travel the three carriers are effectively tied because they share the 7 kg cabin norm, so you should simply book the lowest base fare with convenient timing. Baggage policy only changes the ranking once you add a checked bag.
Do I need to declare sports gear or musical instruments in advance?
Yes. Bicycles, golf bags, surfboards and large instruments fall under special or oversize baggage rules with separate handling fees and usually require advance declaration. Turning up undeclared on a full flight risks offload, so check the airline's special-baggage page and pre-book.
