I've spent embarrassing amounts of time testing natural-language queries on AI flight search tools. These are the 13 prompts that consistently surface cheaper options — including ones designed specifically for Tier-2 city travellers.
TL;DR — Why Natural-Language Queries Beat Standard Search Forms
Natural-language flight search lets you express real constraints — budget, flexibility, preferred airline, acceptable layover time — in a single sentence rather than clicking through multiple filter dropdowns. When tested on tools like FlightGPT and Google Flight Deals, well-structured prompts consistently surface cheaper options than a direct date-and-route search, mainly by triggering flexible-date scanning and multi-airline comparison automatically. Here are 13 prompt templates that actually work, with notes on when to use each.
Budget Queries — Getting the Cheapest Possible Fare
These work best when you have a firm budget and some date flexibility. The key is to state the budget as a hard constraint and let the tool find the dates.
Query 1:
'Cheapest one-way IndiGo flight from Delhi to Goa in the next three weeks. I don't mind early morning or late night.'
Why it works: specifying the airline (IndiGo) and time flexibility surfaces lower-demand departure slots. Early morning and late night departures are typically priced lower — sometimes meaningfully so — on popular leisure routes.
Query 2:
'Return flight Mumbai to Bengaluru, departing any Friday or Saturday in July, returning Sunday or Monday same week. Budget under ₹5,000 total. Economy.'
Why it works: weekend trip parameters with a budget ceiling. The tool scans all four Friday+Saturday departure combos for the month against all Sunday+Monday returns.
Query 3:
'What's the cheapest month in 2026 to fly from Kolkata to Singapore? I can travel any time between August and December.'
Why it works: month-level flexible search is where AI tools genuinely outperform manual calendar clicking. Great for planning trips months ahead without a fixed date.
Tier-2 City Queries — Flying From Lucknow, Indore, Jaipur and Smaller Airports
This is where I spend most of my time, and these queries are legitimately harder to execute on standard OTA forms because Tier-2 departures often require connecting flights that don't appear prominently.
Query 4:
'Cheapest flights from Lucknow to anywhere in Europe in September. Economy. I don't mind one stop, but max 14 hours total travel time.'
Why it works: open destination + layover constraint forces the tool to find routing options you'd never manually check — Lucknow to Frankfurt via Delhi or Lucknow to Amsterdam via Dubai, compared side by side.
Query 5:
'Is it cheaper to fly from Indore to Tokyo directly, or should I go to Delhi first and then fly to Tokyo? Compare for October travel.'
Why it works: head-to-head routing comparison that a standard search form can't do. AI tools can evaluate the cost of the self-transfer option vs a through-fare.
Query 6:
'Flights from Jaipur to Bangkok, flexible within 10 days either side of 15 October. Return 10–14 days after departure. Show me the cheapest combination.'
A classic gap-style query for Tier-2 cities — you get a 20-day departure window and a 4-day return window, and the tool scans all combinations.
Multi-Leg and Complex Itinerary Queries
This is where natural-language queries have the biggest edge over standard booking forms, which handle multi-city travel poorly.
Query 7:
'I want to fly Hyderabad → Kuala Lumpur → Tokyo → back to Hyderabad, spending about a week in each city. Find the cheapest combination for November. Economy. I don't need the flights to be on the same airline.'
Why it works: open-jaw multi-city itinerary. The 'different airlines okay' instruction is important — it opens up mix-and-match options that single-carrier booking would miss.
Query 8:
'I need to be in Amsterdam on 10 September for a 5-day conference. What's the cheapest way to fly from Chennai, and is flying via London or Dubai cheaper? Return flexible between 15–20 September.'
Query 9:
'Cheapest round trip from Pune to New York between October and December. I'm okay with up to two stops. Show me which months are cheapest first, then the specific cheapest flight.'
The two-step instruction ('cheapest months first, then specific flight') is useful — it surfaces the seasonal pattern before drilling into specific dates.
Airline-Specific and Loyalty Queries
If you're chasing miles or have airline preferences, these prompts work well.
Query 10:
'Cheapest Air India flight from Delhi to London next month. I want to earn Flying Returns miles. Economy class only. Show me the lowest base fare options.'
Query 11:
'IndiGo or Akasa Air only — cheapest flight from Bengaluru to Kolkata in the next two weeks. Morning departure preferred but will consider others if the price difference is more than ₹800.'
The conditional ('will consider others if the price difference is more than X') is genuinely useful — it makes the trade-off explicit and lets the tool surface alternatives only when they're meaningfully cheaper.
Last-Minute and Time-Sensitive Queries
For last-minute travel, these prompts help you find the least-bad option in a high-demand window.
Query 12:
'I need to fly from Mumbai to Delhi this weekend — tomorrow or day after — for a family emergency. What's the cheapest available flight with seats right now? Any airline, any time.'
The 'any airline, any time' instruction is important last-minute because carrier preference should be set aside when you need to move.
Query 13:
'Are there any flights from Ahmedabad to Goa this Friday under ₹3,500 one-way? If not, what's the cheapest available and is the price likely to drop before Friday?'
The second part of this query (price trend) won't always be answered accurately — but it prompts the tool to give you a directional view rather than just the current price snapshot.

How to Structure Any Natural-Language Flight Query
After testing dozens of variations, here's the structure that consistently gets better results:
- Origin city (be specific — airport code if you know it): 'from Lucknow (LKO)' rather than just 'from Lucknow'
- Destination — can be open: 'to Bangkok' or 'anywhere in Southeast Asia'
- Date range — not a specific date: 'between 10 and 20 August' or 'any weekend in September'
- Budget constraint (optional but powerful): 'under ₹25,000 return'
- Airline preference or absence of it: 'IndiGo only' or 'any airline'
- Layover tolerance: 'direct only' or 'one stop OK if under 3 hours'
- What you want first: 'show me cheapest months' or 'find the three cheapest options'
You don't need all seven elements. But the more constraints you state explicitly, the less the tool has to guess — and the more the result matches what you actually want. Try these on FlightGPT's search and see how the results differ from a standard form-fill search.

Frequently asked questions
Do natural-language queries actually find cheaper flights than normal search?
They find cheaper options more efficiently — particularly through flexible-date scanning and multi-airline comparison triggered by the way you phrase the query. The underlying fare data is the same; the advantage is that a natural-language query automatically applies constraints (date ranges, airline preferences, budget caps) that would take multiple filter clicks to replicate on a standard search form. The savings are most significant when you have genuine date flexibility — typically in the range of 10–40% versus searching for a specific date on a busy route.
Which AI flight search tools understand Indian-specific queries best?
FlightGPT is optimised for Indian traveller context — rupee pricing, Indian airline names, Tier-2 city airport codes. Google Flight Deals (launched August 2025, India-available) handles Indian routes well with good calendar visualisations. ChatGPT+Skyscanner is better for international inspiration queries. For domestic Indian routes, FlightGPT or a direct ixigo/Skyscanner search with natural-language input tends to work best.
Can I use these query templates on Google Flights?
Google Flights has a Flexible Dates calendar and an 'Explore' mode that handles some of these use cases, but it isn't a conversational AI search — you can't type a sentence and have it parse your constraints. Google's AI-powered Flight Deals feature (separate from standard Google Flights) supports more natural input, but for fully conversational queries, dedicated AI search tools handle these better.
What's the best way to search for flights from smaller Indian airports?
Include the airport code in your query to avoid ambiguity ('from Indore, IXI' or 'from Jaipur, JAI'). Specify that you're okay with one connecting stop, since direct service from Tier-2 cities is limited on many routes. AI tools are particularly useful here because they can surface connecting-flight combinations (like Indore → Mumbai → Dubai) that a standard OTA search might not present prominently.
How specific should I be about dates in a natural-language flight query?
More specific than you think, but not a specific date. The sweet spot is a range: 'between 10 and 25 August' rather than 'in August' (too vague) or '14 August' (specific date, no flexibility). A 10–15 day window gives the tool enough room to find the cheapest days within your range. If you're genuinely open on timing, say 'cheapest month between July and October' and let the tool surface the seasonal pattern first.
Do these prompts work in Hindi?
Some tools handle Hinglish — mixing Hindi and English — reasonably well. FlightGPT's NLP is optimised for Indian English. For fully Hindi queries, ixigo's TARA assistant has the best Hindi support among major Indian travel tools as of 2026. For complex multi-leg or budget-optimisation queries, English tends to give more consistent results across all tools.
