IndiGo's 6Eskai AI: Can It Really Book Flights for You?

IndiGo built 6Eskai on GPT-4 and claims it has cut their customer-agent workload by 75%. That's a striking claim. Here's what actually happens when you try to book, change, or query a flight through it.
TL;DR — What Is 6Eskai and Can It Book Your IndiGo Flight?
6Eskai is IndiGo's AI-powered virtual assistant, built on a GPT-4 foundation and accessible through the IndiGo website and app. It handles flight searches, booking assistance, check-in queries, and common customer-service tasks across around 10 Indian and international languages. It can surface flight options and guide you through the booking flow — but payment still goes through IndiGo's standard checkout. For support tasks, it's genuinely efficient. For pure fare discovery across airlines, you'll get more options from a metasearch first.
What Does 6Eskai Actually Run On?
IndiGo built 6Eskai on OpenAI's GPT-4 architecture, which puts it a tier above the rule-based chatbots that most Indian airlines were still running as recently as 2023. The practical difference is conversational coherence — 6Eskai can handle multi-turn queries, remember what you said earlier in the session, and respond to follow-ups like 'what if I travel a day later' without losing context.
The 75% agent-workload reduction IndiGo quotes publicly refers to their customer service volumes — the volume of queries that previously needed a human agent now being handled at first contact by 6Eskai. That's plausible for the long tail of support queries: flight status, baggage allowance, check-in window, seat upgrade availability. These are query types where a well-trained model can answer reliably without needing live agent judgment.
What it doesn't mean: that 6Eskai is replacing the booking funnel. It's a support-first system that also has search capabilities — not a dedicated flight-pricing engine.
Booking a Flight Through 6Eskai: What the Flow Looks Like
I went through the booking flow multiple times on IndiGo's website. You open the 6Eskai chat widget, type in your route and dates, and it returns a shortlist of available flights pulled from IndiGo's own inventory. Makes sense — it's IndiGo's own assistant, so it only shows IndiGo flights.
The results it returns are the same as what you'd find using IndiGo's main search page, typically sorted by price with optional filters. The chatbot adds value by letting you express preferences conversationally ('morning flights only, non-stop') rather than clicking filters. If you're comfortable with filter interfaces, you're probably just as fast doing it yourself.
The checkout handoff is smooth — 6Eskai passes your selected flight and passenger count to the booking form, you fill in traveller details and payment. UPI and standard card options are all there, same as the main site. No hidden payment surcharges from going through the chatbot path vs direct search.
One thing worth knowing if you're comparing fares: IndiGo on the IndiGo website sometimes has pricing that differs slightly from IndiGo fares on third-party OTAs, partly due to OTA service fees. Always worth checking a metasearch or comparing the airline-direct price before assuming the OTA is cheaper or equal.
The 10-Language Claim: Which Languages Actually Work Well?
IndiGo's official communication references support for around 10 languages including Hindi, Tamil, Kannada, Telugu, Bengali, Marathi and English. In my testing, Hindi was the strongest — natural sentences, good date parsing, solid understanding of travel intent. English was predictably polished given the GPT-4 base.
Tamil and Telugu were functional for straightforward queries ('cheapest flight to Hyderabad this weekend') but less graceful with anything conversational or compound. I didn't test Kannada and Marathi extensively, but based on the pattern, your mileage will vary by query complexity. For booking in regional languages, keep sentences simple and direct — the chatbot copes better with 'Bangalore to Delhi, 20 June, one adult' than a full paragraph of preferences and constraints.
Worth noting: language support for AI assistants in India is improving quickly across 2025-2026. If you tried a regional language on an airline chatbot a year ago and gave up, it may be worth retrying.
Where 6Eskai Genuinely Earns Its Keep: Customer Support
This is where I'd actually recommend 6Eskai over waiting for a human agent. Common queries it handles well and quickly:
- Flight status and delays for IndiGo flights
- Baggage allowance by fare type (6E Lite vs. regular vs. 6E Flexi)
- Check-in window reminders and seat selection availability
- Initiating refund or cancellation requests (though resolution still takes standard processing time)
- Meal preference queries and add-on ancillary information
For a cancellation, 6Eskai can tell you the applicable cancellation fee for your fare type, initiate the request, and give you an estimated refund timeline. The refund then follows normal IndiGo processing — typically a few business days to the original payment method for most eligible fare classes, longer for some promotional fares. Verify your specific fare rules on IndiGo's refund policy page, since these do change.
What it can't do: override fare rules, apply promo codes retroactively, or escalate urgent cases to the right human faster than their standard queue. For genuinely complex service failures, you still need a human eventually.
Fare Accuracy and the One Big Structural Limit
6Eskai's fare accuracy is fine — it's pulling live IndiGo inventory. The prices it shows are real. The structural constraint is that it only shows IndiGo flights. If the cheapest option for your route on a given day is Akasa Air, Air India Express, or even Air India on a connecting route, 6Eskai won't tell you. It can't — it's an IndiGo product.
For purely domestic travel where you're already decided on IndiGo, this is fine. For route or fare comparison across airlines, you need to either check each airline directly (tedious) or use a metasearch platform that aggregates them. That's the honest limitation of any single-airline chatbot, and it applies to Air India's AI.g and Akasa's equivalent just as much as to 6Eskai.
The Verdict: Solid Support Tool, Limited as a Booking Discovery Engine
6Eskai is a well-built airline chatbot that does what it's designed to do — handle customer support queries efficiently and guide existing IndiGo customers through bookings. The GPT-4 backbone gives it better conversational quality than most airline chatbots I've used in India. The language breadth is genuine progress, even if not all languages are equally polished.
But the 75% agent-workload reduction stat is about support efficiency, not about 6Eskai giving you a better deal on flights. If you want to find the lowest fare across IndiGo, Air India, Akasa and Air India Express for your route, start with a metasearch, find the best option, then use the airline's own site (or 6Eskai, if it's IndiGo) to complete the booking. That workflow almost always beats starting inside a single airline's chatbot.
Also worth checking: IndiGo's own OTA-based AI tools like MakeMyTrip's Myra occasionally surface IndiGo fares with OTA-specific coupons that make them cheaper than airline-direct. Always compare before you confirm.
Frequently asked questions
Does IndiGo 6Eskai complete the full booking including payment?
6Eskai handles flight search and selection, then hands you off to IndiGo's standard booking form for passenger details and payment. Payment is processed through IndiGo's checkout, not the chatbot itself. UPI, credit card and debit card are all supported as normal.
What is 6Eskai's GPT-4 backbone and why does it matter?
GPT-4 is a large language model from OpenAI that powers 6Eskai's ability to understand natural-language queries, maintain context across multiple turns in a conversation, and respond coherently to follow-up questions. In practice, it means 6Eskai handles complex or conversational queries better than older rule-based airline chatbots that only understood specific keywords.
Can 6Eskai help me cancel or change an IndiGo flight?
Yes — 6Eskai can initiate cancellation and change requests, tell you the applicable fee for your fare type, and give you an estimated refund timeline. Standard IndiGo refunds to the original payment method typically take a few to several business days depending on the fare class. Verify your specific fare rules on IndiGo's official cancellation policy page.
Does 6Eskai offer flights from other airlines besides IndiGo?
No. 6Eskai is IndiGo's own product and only shows IndiGo inventory. For cross-airline fare comparison, you need a third-party OTA or a metasearch tool like <a href='/'>FlightGPT</a> that aggregates results from IndiGo, Air India, Akasa Air and others in one view.
Is 6Eskai available 24/7?
The AI chatbot is available around the clock for standard queries like flight status, baggage info and booking assistance. For queries that escalate to human agents, availability depends on IndiGo's support hours. Check IndiGo's current support page for live agent availability windows.
