How to Compare Flight Prices: Aggregators, Meta-Search & AI Tools Explained
By Vihaan Patel (Vihaan Patel covers the intersection of travel and digital payments — Indian OTAs, airline-direct booking flows, UPI vs credit-card surcharges, RBI tokenisation rules and the booking-funnel mechanics that quietly cost (or save) you money.) · Published · 11 min read
Why the same flight costs ₹3,200 on one site and ₹4,500 on another — and the three-tool stack that consistently finds the cheapest fare.
OTA, meta-search and AI search — the three categories
Every flight search tool falls into one of three categories. Knowing which is which determines how you should use them.
- OTAs (Online Travel Agencies): they sell tickets directly. They have a contract with the airline, hold inventory, collect your payment, issue the ticket and handle the booking. Indian OTAs include MakeMyTrip, Cleartrip, EaseMyTrip, ixigo (also a meta-search), Yatra and Goibibo.
- Meta-search engines: they do not sell tickets. They pull fares from multiple OTAs and airlines and show you the cheapest, then send you to that source to book. Examples: Skyscanner, Google Flights, Kayak, Momondo, Wego.
- AI search tools: a newer category. They combine meta-search-style data access with a natural-language interface and the ability to scan flexible dates, multi-city routings and constraints in one query. Example: FlightGPT.
An OTA shows you its own fare. A meta-search shows you everyone's fares. An AI search lets you ask for what you actually want and does the scanning for you.
Why prices differ across sites for the same flight
You search Delhi-Singapore on five different sites. Same flight, five different prices. Here is why:
- Different fare buckets shown. Airlines distribute fare classes to different distribution channels. An OTA may have access to a specific net fare that is not loaded into the GDS used by another OTA.
- Different convenience fees and surcharges. Each OTA adds its own service fee — ₹50 to ₹350 per ticket — and may load credit-card surcharges.
- Different inclusions. One OTA bundles a free meal or seat; another excludes them. The headline fare is not always comparing the same product.
- Different currency & GST handling. Some sites display the pre-GST fare; some display post-GST.
- Different promo applications. An active card promo on MakeMyTrip will not show on Skyscanner.
- Cache lag. Meta-search sites pull fares every few minutes. The price you see may be 90 seconds out of date.
This is why the "cheapest" in a meta-search is not always the cheapest after you click through to the OTA. Always verify the final, all-in total on the booking page before paying.
Side-by-side — the major tools Indian travellers use
| Tool | Type | Best for | Weakness |
|---|---|---|---|
| FlightGPT | AI search | Natural-language queries, flexible dates, multi-city, constraint-based search | Newer; final ticket issuance handled by partner OTA / airline |
| Google Flights | Meta-search | Price history graph, calendar view, price alerts, "Cheap/Typical/High" signal | Some Indian LCC promo codes not shown; weaker on multi-city |
| Skyscanner | Meta-search | "Everywhere" search, cheapest-month, broad LCC coverage | UI clutter; affiliate-driven sort order |
| Kayak | Meta-search | Hacker Fares (split tickets), Explore map view | Weak Indian carrier coverage; better for US/EU markets |
| Momondo | Meta-search | Aggressive low-fare surfacing; LCC coverage | Same parent as Kayak; weaker India focus |
| MakeMyTrip | OTA | Indian payments, MyBiz corporate, hold-fare-for-24-hours feature | Convenience fees, opt-out insurance |
| Cleartrip | OTA | Flipkart promos, clean UI, Cleartrip Easy bus & train | Sometimes-laggy refund cycles |
| EaseMyTrip | OTA | Zero convenience fee, Axis-tied promos, refunds on certain fares | Smaller international inventory than MMT |
| ixigo | OTA + meta | Train + flight combos, fare alerts, AI assistant Maya | Mostly Indian-domestic strength; international thinner |
| Yatra | OTA | Corporate travel, e-cash wallet | UX dated |
| Wego | Meta-search | Strong Gulf-region coverage | UI ads |
How meta-search actually works (under the hood)
When you type Delhi-Dubai on Skyscanner, what happens?
- Skyscanner sends parallel queries to dozens of sources: the GDS (Amadeus, Sabre, Travelport), direct airline APIs (Emirates, Air India, IndiGo, flydubai), and OTA partner feeds (MakeMyTrip, Cleartrip, Trip.com, Kiwi).
- Each source returns the fares it currently has loaded for that route/date.
- Skyscanner deduplicates (same flight from different sources), sorts by price, and shows you the cheapest.
- When you click "Select", Skyscanner sends you to the source that has that fare — the airline or the OTA — and you book there.
Skyscanner does not hold inventory and does not handle your payment. Its job is the price discovery, not the booking. This is why your post-booking support comes from the OTA or airline, not Skyscanner.
Where AI search fits in
Meta-search has a structural weakness: you have to know what you are searching for. You pick a date, a from-airport, a to-airport. If you want "cheapest Delhi to a beach in September under ₹25,000, no overnight layovers", traditional meta-search forces you into 50 separate searches.
AI-native search like FlightGPT changes this in three ways:
- Constraint-driven search. Type the constraints in plain English; the AI runs the matrix of searches in parallel and surfaces matching options.
- Flexible dimension scanning. "Cheapest week in October" or "cheapest weekend in the next two months" are single queries, not 60 manual searches.
- Cross-route reasoning. "Should I fly Delhi-Bali direct via Singapore, or take a separate Delhi-Singapore + Singapore-Bali combo?" — the AI can compare both routing strategies.
The output is then a curated list, often with two or three different routing options at different price points, instead of a single sorted list. For complex or flexible trips, this is a significant time-saver. For a simple Delhi-Mumbai on a fixed date, meta-search is still fast enough.
Which tool to use when — a decision tree
- Fixed dates, fixed route, simple round-trip. Start with Google Flights for the price history view, then click through to the cheapest OTA. Cross-check the airline website.
- Flexible dates or flexible destination. Start with FlightGPT for AI scanning, or Skyscanner's "cheapest month" / "everywhere" views.
- Multi-city or open-jaw. FlightGPT, Google Flights multi-city, or directly the airline website for the best multi-city pricing.
- Domestic India only. ixigo, EaseMyTrip and the airline app (IndiGo, Akasa) — Indian-domestic promo coverage is best there.
- Long-haul to US / Europe / Australia. Google Flights for price history, Skyscanner for broad coverage, FlightGPT for routing alternatives, airline for final book if competitive.
- Premium cabin (Business / First). Compare meta-search to airline directly — paid premium fares vary widely and direct airline often wins on perks.
The three-tool stack we recommend
You do not need ten tabs. The cleanest workflow:
- FlightGPT first, for the AI scan. It gives you a starting view of the cheapest routings and dates within your constraints.
- Google Flights second, to validate the fare against price history and to set an alert if you are not ready to book.
- The airline website third, to confirm the final price (and any seat/baggage costs) before booking.
If all three agree on a fare and the airline is within ₹500 of the OTA, book the airline direct. If the OTA is meaningfully cheaper, book the OTA but verify the inclusions. This stack catches the cheapest fare 90%+ of the time without endless tab-switching.
What to verify before clicking "Pay"
- Final all-in total — fare + taxes + convenience fee + insurance opt-out + seat + baggage.
- Baggage allowance — basic fares on Air India Express, IndiGo international and SpiceJet sometimes exclude check-in. Re-check.
- Cancellation rules — non-refundable, partial refund (₹3,000-₹5,000 cancellation fee), or fully refundable.
- Schedule change protection — airline-direct bookings get notified faster than some OTAs.
- Passenger name spelling — exactly as per passport for international; surname-first only if the airline asks.
- Connection times — anything under 90 minutes international or 60 minutes domestic is risky.

Frequently asked questions
What is the difference between Skyscanner and MakeMyTrip?
Skyscanner is a meta-search engine — it does not sell tickets, it shows you the cheapest fares from multiple OTAs and airlines and sends you to them to book. MakeMyTrip is an OTA — it sells tickets directly, holds your payment and issues the e-ticket. Use Skyscanner to find the cheapest source; book on MakeMyTrip or the airline.
Is Google Flights better than Skyscanner for Indian travellers?
Google Flights is better for price history and alerts; Skyscanner is better for 'everywhere' / 'cheapest month' flexible searches and LCC coverage. Use both — they take 30 seconds each and surface different lowest fares about 1 in 4 times.
Why do flight prices differ between websites for the same flight?
Because different OTAs have access to different fare buckets, add different convenience fees, apply different promo codes, and handle GST display differently. The same Air India seat can appear at ₹14,200 on one site and ₹15,800 on another. Always compare the final all-in total.
Is FlightGPT an OTA or a meta-search?
FlightGPT is an AI-native flight search tool. It combines meta-search-style data access with a natural-language interface and flexible-date / multi-city scanning. Booking is completed via the partner airline or OTA — FlightGPT focuses on price discovery and trip planning.
Should I book on the airline website or an OTA?
Compare both before booking. The airline is usually within ₹500 of the cheapest OTA, sometimes cheaper without convenience fees. The airline also handles schedule changes and cancellations directly, which is faster than going through an OTA. If the OTA is meaningfully cheaper (₹1,000+), book the OTA — but verify inclusions.
Does Kayak work well for flights from India?
Kayak's coverage of Indian carriers is thinner than Skyscanner's or Google Flights'. It is fine for international routes from India (especially to the US/Europe) but for purely Indian-domestic or short-haul international, ixigo, FlightGPT and Skyscanner are usually stronger.
Are AI flight search tools accurate?
Modern AI flight tools like FlightGPT pull from the same live fare feeds as Google Flights and Skyscanner, so price accuracy is comparable. The difference is in the interface — natural-language queries and flexible-date scanning surface options that traditional meta-search would require dozens of manual searches to find.
