Air India vs IndiGo 2026: Total Cost Comparison Including All Fees

IndiGo's headline fare almost always looks cheaper than Air India's — until you add 25 kg of baggage, a reserved seat, and a meal. On certain routes and for certain travellers, Air India's all-inclusive legacy model flips the result. Here's the honest total-cost math.
TL;DR — Which Is Cheaper?
For a light traveller with just a cabin bag, IndiGo is almost always cheaper than Air India on domestic routes. But once you add 25 kg check-in baggage, a window seat, and a meal, the gap narrows — and on some routes Air India's bundled economy fare can actually be cheaper in total. The route, the day, and how much stuff you carry are what decide the winner, not loyalty to a logo. Use FlightGPT to run a quick side-by-side with your actual bag weight before booking.
The Baggage Allowance Gap — Air India's Biggest Structural Advantage
This is the number that most people miss when they do a quick OTA fare search. IndiGo's base economy fare on domestic routes typically includes 15 kg of check-in baggage. Air India's base economy includes 25 kg. That 10 kg difference matters more than most people realise.
If you're flying with a 22 kg bag on IndiGo, you're buying 7 kg of excess. Add that cost to IndiGo's base fare and compare with Air India's base fare — because Air India's 25 kg fits your 22 kg for free. Depending on the route and how far ahead you add baggage on IndiGo, the extra cost can be anywhere from a few hundred to well over a thousand rupees per flight.
For someone flying domestically a dozen times a year with a full-size bag, this compounds into a genuinely meaningful annual difference. Verify the exact allowance for your fare class on Air India's official site and IndiGo's site — both carriers have multiple fare families and the included allowance varies.
| What You're Comparing | IndiGo (base economy) | Air India (base economy) |
|---|---|---|
| Check-in baggage included | 15 kg | 25 kg |
| Cabin baggage included | 7 kg | 8 kg |
| Meal included | No (buy onboard) | Yes (on most domestic flights) |
| Seat selection (standard) | Paid (₹100–₹500+ typical) | Often free at check-in or low-cost online |
Seat Fees: The Small Line Item That Adds Up
IndiGo charges for almost every reserved seat on domestic flights. A standard middle seat near the back tends to cost the least — sometimes as little as ₹100 — but a window or aisle in a good row can run ₹300–₹600 per segment easily. On a return trip that's potentially ₹600–₹1,200 extra before you've done anything else.
Air India's seat fees are generally lower, and for certain fare families, standard seats in the middle and back sections are available free at check-in or for a small fee online. If you travel as a couple and need to sit together, this matters. I've ended up in separate rows on IndiGo more times than I care to count because I didn't want to pay the seat fee — and I always regret it.
The lesson: factor in the seat cost when comparing fares, especially on trips of 2 hours or more.
Meal Costs: Where IndiGo Adds Up Quietly
Air India includes a meal on virtually all domestic flights. IndiGo does not — food is buy-on-board, and the prices onboard are, shall we say, airport-grade. A sandwich and a coffee on an IndiGo flight will cost you somewhere in the ₹300–₹500 range depending on what you order.
If you and a travel companion both want to eat, that's an easy ₹600–₹1,000 added to the IndiGo cost on a 2-hour flight. Pre-ordering meals on IndiGo (via their app before the flight) is cheaper than buying onboard, but it's still an extra step and an extra cost that Air India doesn't ask you to think about.
For short hops under 90 minutes, most people can skip the meal. But on the Delhi–Kochi or Mumbai–Chennai sector, a 2.5 hour flight with nothing to eat feels longer than it is — especially if you're in a middle seat.
Route-by-Route Reality: When Does Air India Actually Win?
Let's be honest — IndiGo wins on total cost more often than not, especially for solo light travellers. But here are the specific scenarios where Air India flips the result:
- Heavy bags: Any traveller with a consistent 20+ kg bag. The 25 kg base allowance alone can offset a fare premium of ₹500–₹800 on many routes.
- Long domestic routes (2+ hours): Add meal + seat + baggage and Air India's bundled proposition starts looking rational on routes like Delhi–Kochi, Mumbai–Guwahati, or Chennai–Delhi.
- Late-night/early-morning slots: Air India sometimes has lower demand on certain time slots and prices them very aggressively. Their 2026 pricing has become noticeably more dynamic than the old PSU days.
- Business class upgrades: Air India's business cabin on domestic routes (when available) is often priced closer to IndiGo's premium economy equivalent than you'd expect. Worth checking for a 3-hour flight.

The Light-Traveller Case: IndiGo Still Usually Wins
I want to be fair to IndiGo here, because their business model genuinely delivers value for a certain kind of traveller. If you're flying with just a laptop bag, booking early, not fussed about seat selection, and skipping the meal — IndiGo's base fares on trunk routes like BOM-DEL or BLR-HYD are often meaningfully lower than Air India's equivalent.
IndiGo's on-time performance record is also one of the strongest in India, consistently better than most competitors across quarterly DGCA data. For a business traveller where punctuality matters more than a sandwich, that reliability has real value. Check the latest DGCA OTP (on-time performance) reports at dgca.gov.in for the most recent numbers.
The short version: travelling light with just cabin baggage = IndiGo wins. Travelling with a full bag, eating onboard, and wanting a seat next to your partner = do the total-cost math first, because Air India may surprise you.
Frequent Flyer Programs: Flying Returns vs. IndiGo's 6E Rewards
Both carriers have loyalty programs worth knowing about. Air India Flying Returns is the older, more established program with partners across hotel, car rental, and international airline networks via Star Alliance (Air India joined Star Alliance). Points earn on Air India, Air India Express, and several partners. Redemptions on business class can be strong value.
IndiGo's 6E Rewards program works on a cashback/credit model rather than traditional miles. Points are earned on IndiGo bookings and can be redeemed for flight discounts. It's simpler but less flexible than Flying Returns for international redemptions.
If you fly internationally often — say, BOM-LHR or DEL-JFK — Air India's Star Alliance membership makes Flying Returns miles meaningfully more valuable. For purely domestic frequent flyers, IndiGo's program is more straightforward but the earn rates and redemption values change, so verify current terms on each program's page before deciding which to chase.

Bottom Line: How to Decide
Here's my personal heuristic after booking hundreds of domestic flights out of Tier-2 cities. Before confirming any booking, I add: base fare + seat selection + baggage fee + meal (if I want one). Only then do I compare. Nine times out of ten this changes which airline is actually cheaper.
If that math takes too long, just use FlightGPT — the AI search can surface both carriers on your route quickly so you can weigh the full picture instead of chasing a ₹300 headline fare difference that evaporates the moment you add your bag.
And one last thing: always verify the current baggage allowance, fee schedule, and seat policy on the airline's official website before booking. These numbers shift, and what's true in June may be different by October.
Frequently asked questions
Is Air India always more expensive than IndiGo on domestic routes?
No. Air India's headline fare is often higher, but once you add IndiGo's baggage fees (for bags over 15 kg), seat charges, and meal costs, the total can come out within ₹200–₹600 of Air India on many trunk routes. On some specific flights and timings, Air India is actually cheaper all-in. Always compare the total, not just the base fare.
Does Air India include 25 kg check-in baggage on all domestic economy tickets?
Generally yes on standard economy fare classes, but Air India now has multiple fare families (like Lite and Economy) with different allowances. The 25 kg is typical for their main economy tiers. Confirm the specific allowance for your fare class on Air India's official website at airindia.com before booking.
How much does IndiGo charge for excess baggage at the airport vs. online?
Buying excess baggage at the IndiGo counter is typically 50–100% more expensive than pre-purchasing online before your flight. Online rates for domestic flights are roughly ₹200–₹350 per kg depending on the route and how far ahead you buy; airport rates are often ₹450–₹700 per kg. Buy online well before travel, not at the gate.
Which airline has better on-time performance — Air India or IndiGo?
IndiGo has historically led DGCA on-time performance rankings among Indian carriers. Air India's OTP has improved since the Tata group takeover, but IndiGo remains the benchmark for punctuality on domestic routes. Check the latest DGCA monthly OTP report at dgca.gov.in for current data — numbers shift quarter to quarter.
Should I book Air India or IndiGo for an international connection?
If you're connecting to an international flight, Air India's 25 kg domestic allowance often aligns better with international economy allowances, reducing the chance of a fee mismatch. IndiGo's international routes have their own baggage rules. Through-ticketing (booking domestic + international on one PNR) is the cleanest option when available — FlightGPT can surface combined itineraries worth checking.
Does Air India still have Vistara flights after the merger?
No. Vistara completed its merger into Air India in late 2024. All Vistara flights, aircraft, and routes now operate under the Air India brand. If you held Club Vistara points, check your Air India Flying Returns account — conversions were carried out during the merger process, but verify the status of your miles on Air India's Flying Returns portal.
