IRCTC Air vs AI-powered OTAs: which gives you cheaper India fares in 2026?

IRCTC Air is the only zero-convenience-fee channel for IndiGo and Air India fares — but AI-powered OTAs surface flexible-date options and multi-source comparisons IRCTC simply can't. The honest answer is: both, for different jobs.

TL;DR — the short answer

IRCTC Air charges zero convenience fee on IndiGo and Air India bookings, which can save you ₹200–₹600 per booking compared to the standard OTA fee. That's a genuine advantage for price-sensitive travellers who know exactly which flight they want. Where IRCTC Air falls short is flexibility — there's no flexible-date grid, no side-by-side multi-airline comparison, and the search UI feels like it was designed in 2019. AI-powered flight search tools (like FlightGPT, MakeMyTrip's GenAI layer, or Cleartrip) let you ask 'cheapest time to fly Mumbai to Delhi next month' and get a real answer across multiple airlines. The smart move: search on an AI tool to find the best flight, then check if the same fare is available on IRCTC Air to avoid the convenience fee.

What exactly is IRCTC Air and why is it different?

IRCTC Air is the flight booking arm of the Indian Railway Catering and Tourism Corporation — the same government entity that runs rail ticket sales on irctc.co.in. IRCTC has agreements with IndiGo and Air India (and some international carriers) that allow it to sell tickets at net fares, passing the saving on to passengers as a zero-convenience-fee deal.

This matters because every commercial OTA — MakeMyTrip, Cleartrip, Ixigo, EaseMyTrip — adds a convenience fee at checkout. Fees typically run in the range of ₹149–₹499 per booking (not per passenger), though OTAs run promotional periods where this drops to zero. IRCTC Air's zero-fee pledge is structural, not promotional.

The other advantage that gets less attention: IRCTC Air issues a proper GST invoice automatically, tied to your IRCTC account's registered GSTIN if you've added one. For small business owners or freelancers who want to claim input tax credit on domestic travel, this is a genuine win over some OTAs that make you chase the invoice separately.

What IRCTC Air does not do: it doesn't cover SpiceJet or Akasa Air well, it has no hotel or cab bundling, and the interface shows only fixed-date fares with no calendar view. You're on your own to figure out if Wednesday is ₹800 cheaper than Friday.

What AI-powered OTAs actually do better

The term 'AI search' gets thrown around loosely, but there are concrete things modern flight search tools do that IRCTC simply can't match. When I used FlightGPT to search for flights from Indore to Bengaluru for a conference, the flexible-date view immediately showed me that flying on Tuesday instead of Monday saved a meaningful amount — something I'd have had to manually check date-by-date on IRCTC Air.

Specifically, AI-powered search tools in 2026 can:

MakeMyTrip has also added a GenAI assistant layer (currently in beta on the app) that can answer questions like 'what's the best time to book Bangalore to Delhi for Diwali?' — though the quality of answers varies and it still funnels you to a fixed-date search eventually.

Refund reliability: where does IRCTC Air actually stand?

This is where it gets nuanced. IRCTC Air is an agent — it sells you the airline's ticket, but refunds go via IRCTC back to you, not directly from the airline. In theory this should be seamless. In practice, I've seen (and heard from readers) that refund timelines on IRCTC Air can run 7–10 business days, occasionally longer if there's a manual review step. The refund amount itself matches airline policy — IRCTC doesn't take a cut there — but the extra hop in the chain adds time.

Booking directly on the airline's own website (IndiGo.com or airindia.com) typically means the refund comes back directly to your card or UPI-linked bank account, with fewer intermediaries. OTAs have variable records here — EaseMyTrip and Cleartrip have improved significantly, but during high-disruption periods (cyclone cancellations, pandemic-era waivers) the OTA buffer has historically caused delays.

For non-refundable saver fares, this mostly doesn't matter — you won't be getting money back either way. For flexi or fully refundable fares, booking direct on the airline site is probably the cleanest path. IRCTC Air is best suited to non-refundable budget fares where the zero convenience fee is a clean saving.

GST invoicing: the underrated reason business travellers use IRCTC Air

If you are claiming travel reimbursements or filing GST returns, the invoice situation across Indian booking channels is genuinely messy. Airlines issue their own tax invoice; OTAs issue a separate service invoice for their fee; and if you're claiming input tax credit (ITC) on the airfare itself, you need the airline's invoice, not the OTA's.

IRCTC Air's automatic GST invoice — which includes the 5% GST levied on domestic air travel under HSN 9964 — is tied to your IRCTC account. Add your company's GSTIN once, and every booking comes with a clean invoice. Air India's own website also does this reasonably well. IndiGo's own site is less consistent — sometimes the invoice requires a separate request via customer care.

For frequent business travellers making 20–30 domestic bookings a year, this admin saving is not trivial. Verify GST applicability for your specific fare type and company setup with your CA — rules on ITC for business travel have nuances that depend on your industry and GST registration.

The hybrid strategy: search smart, book cheap

The workflow that has saved me real money over two years of obsessive fare-tracking:

  1. Search on FlightGPT or MakeMyTrip with the flexible-date view to find which date, time, and airline combination works best.
  2. Note the flight number and fare class.
  3. Check if that exact flight is available on IRCTC Air or the airline's direct site. If the fare matches and you save ₹200–₹399 in convenience fees, book there.
  4. If there's a meaningful OTA cashback offer (HDFC Bank card + MakeMyTrip, for instance, or ICICI Bank on Cleartrip) that exceeds the convenience fee, the OTA deal might win. Run the maths.

The one case where I book OTA without hesitation: hotel + flight bundles where the OTA is genuinely subsidising the package price. Standalone flight bookings are where the IRCTC Air / airline-direct advantage is clearest.

Bottom line

IRCTC Air is a legitimate, often-overlooked booking channel for Indian domestic flights — especially for IndiGo and Air India fares where the zero convenience fee is a real, structural saving. AI-powered search tools are better for discovery: finding the right flight, the right date, and the right airline. Use them as complements, not competitors. Start your search on FlightGPT to find the optimal fare, then check IRCTC Air or the airline's own site to see if you can book without the extra fee.

Frequently asked questions

Does IRCTC Air really charge zero convenience fee on all airlines?

IRCTC Air has zero-convenience-fee arrangements primarily with IndiGo and Air India. For other carriers or international bookings, a small service fee may apply. Always check the fee breakdown on the payment page before confirming — it typically shows up as a separate line item if it exists.

Can I use IRCTC Air for Akasa Air or SpiceJet bookings?

Akasa Air and SpiceJet availability on IRCTC Air is limited or absent in 2026. For those airlines, you're better off booking directly on their own websites (akasaair.com or spicejet.com) to avoid OTA fees. IRCTC Air's coverage is strongest on IndiGo and Air India routes.

How long do IRCTC Air refunds take?

Refunds on IRCTC Air typically take 7–10 business days, though I've seen cases go longer. The refund amount itself follows the airline's cancellation policy. If you need faster refunds, booking directly on the airline's own app or website removes one step from the refund chain and often settles in 5–7 business days.

Is AI flight search trustworthy for booking — or just for price comparison?

FlightGPT is an online travel agency where you search, compare fares across sources, and complete the booking right there. The fare shown is what the source is publishing at that moment; prices can change in the seconds between search and checkout. The fare shown is what the source is publishing at that moment; prices can change in the seconds between search and checkout. Always verify the final price on the booking page before entering payment details.

Which Indian OTA is best for GST invoices on flight bookings?

IRCTC Air and Air India's own website have the most consistent automatic GST invoicing for domestic flights. MakeMyTrip and EaseMyTrip will issue invoices on request, but the process can require a manual follow-up. Cleartrip has improved in this area. For frequent business travel, keep your GSTIN saved in your IRCTC account and check your preferred OTA's invoice delivery process before the year's first booking.

Can AI tools show fare calendar views for India flights?

Yes — tools like FlightGPT, MakeMyTrip, and Ixigo all offer a low-fare calendar or flexible-date grid for most domestic India routes. The depth of the calendar (how many days ahead is shown) varies, but you can typically see 30–60 days at a glance. IRCTC Air does not have this feature as of mid-2026.
