One-Way or Round-Trip Last-Minute? Which Is Cheaper in India

Last-minute round-trips are often a trap. Two separate one-ways — sometimes on different airlines — can beat a return ticket by a wide margin, especially on domestic routes. Here's how to think through it when you're booking within 48–72 hours.
TL;DR — The Fast Answer
For last-minute domestic travel in India, two one-way tickets on the cheapest available carrier often beat a round-trip fare — sometimes by 30–40%. On international routes, the picture is more mixed: full-service carriers sometimes price a return ticket lower than two one-ways on short notice. The right answer depends on the route, the airline, and exactly how last-minute you are. Run both comparisons on FlightGPT before deciding.
Why Last-Minute Round-Trips Are Frequently a Bad Deal
I learned this the hard way booking a Lucknow–Goa return about 36 hours before travel. The round-trip fare was eye-wateringly high. When I priced two one-ways — IndiGo outbound, Air India Express return a week later — the total came out meaningfully cheaper. Here's why this happens.
Indian LCCs (IndiGo, Akasa Air, Air India Express) price one-ways completely independently. There's no "return discount" baked into their model. When inventory is tight last-minute, the outbound might be expensive regardless of what you do on the return — but by mixing carriers and choosing the cheapest one-way in each direction separately, you're not locked into one airline's last-minute premium on both legs.
Full-service Air India does sometimes offer bundled return fares that undercut two one-ways, especially on thinner routes. But even there, it's worth checking both options — Air India's last-minute domestic fares can be high when IndiGo or Akasa still has inventory.
The Multi-Airline Split Strategy for Urgent Domestic Travel
Here's the approach I use when I need to be somewhere in less than 48 hours and I know I'm coming back:
- Search the outbound one-way on every carrier. Note which airline has the cheapest seat and which flight time works.
- Search the return one-way on every carrier for the dates you need. This is a completely separate search — don't anchor to the same airline.
- Compare the sum of the two one-ways against the cheapest round-trip on any carrier.
- Book whichever is cheaper. On domestic routes, two one-ways win maybe 60–70% of the time when you're booking within 72 hours, in my experience.
The practical downside: two separate bookings means two separate cancellation/change processes if plans shift. If the trip is at all uncertain, factor in the flexibility difference. Air India's full-service fares tend to have better change terms than IndiGo's base fares.
How LCC Pricing Actually Works on Short Notice
IndiGo, Akasa, and Air India Express all use dynamic pricing algorithms that push prices up as seats fill and departure approaches. The key thing to understand: they sell seats in buckets. The cheapest bucket might have 2–3 seats. Once those go, the next bucket is pricier. Last-minute, you're almost always buying from a high-priced bucket — but the price difference between carriers can still be significant if one carrier happens to have more inventory on your route.
What drives last-minute inventory on Indian domestic routes? Schedule changes, aircraft swaps, and simply lower demand on certain flights. A 6am departure that's inconvenient for most business travellers might still have cheap seats 24 hours out. A peak-hour departure on a trunk route (Mumbai–Delhi, Bangalore–Delhi) will almost always be expensive last-minute — both as one-way and as part of a return. No trick gets around thin inventory; you're competing with everyone else for the same seats.
SpiceJet, worth a mention: the airline has had a rocky period and operates a limited schedule as of 2026. It sometimes shows very cheap last-minute fares, but check the cancellation track record before booking if the trip is time-sensitive.
International Routes: When Round-Trips Win
The calculation flips on many international routes. This is especially true for:
- Long-haul flights (Delhi/Mumbai to Europe, UK, North America): Airlines like Air India, Emirates, Qatar Airways often price a return ticket as a bundle that's cheaper than two one-ways priced separately. This is because their revenue management systems are designed to fill both legs simultaneously, and they'd rather have you committed to both legs at a moderate price than sell one-ways piecemeal.
- Routes with fewer competing carriers: If there are only one or two airlines on the route, they have less pressure to discount the outbound one-way, so the return bundle can look attractive.
- Middle-East and Southeast Asia hubs within 5–7 days: Dubai, Bangkok, Singapore, Kuala Lumpur routes often have enough capacity that fares don't spike as severely last-minute, and return bundles can still be competitive.
My default on international last-minute: check the round-trip fare first, then price two one-ways. If the gap is under 10%, take the round-trip for the simplicity. If the two one-ways are materially cheaper and your dates are flexible on the return, split it.
Date Flexibility and the Hidden Advantage of Two One-Ways
Two one-ways give you something a round-trip doesn't: independent flexibility on each leg. If your return plans are uncertain — which they often are when you're booking last-minute — being able to change just the return ticket without touching the outbound is genuinely valuable. With a round-trip, changing the return date usually means a change fee that's applied to the entire booking.
This matters most for urgent work trips and family emergencies, which are the two main reasons people book domestic tickets within 48 hours. In both cases, the return date is often the uncertain variable. Two one-ways let you push the return without any impact on your confirmed outbound seat.
For families and groups: the split strategy gets complicated. If you're booking for 4 people, keeping both legs on one booking simplifies the group check-in and baggage coordination. The savings calculation also changes when you multiply across 4 tickets — sometimes a family return fare or a group booking via an agent makes more sense.

How to Actually Run the Comparison Fast
When you're in a hurry, here's the fastest workflow:
Use FlightGPT or Google Flights for the initial price map — both let you see the cheapest options across carriers quickly. Then go direct to the airline site to book (avoids OTA convenience fees of roughly ₹200–700 per ticket). If two different airlines win on outbound vs return, book each directly on their respective sites.
One thing I've found useful: check whether any OTA (MakeMyTrip, EaseMyTrip) has a "combo" deal that bundles two one-ways at a discount. Occasionally these surface and undercut both the round-trip and the separately-booked one-way total. It's not consistent, but worth a 30-second check before you commit.
Also check route pages on FlightGPT — they carry recent fare trend data that can help you set a realistic expectation for what the route should cost before you start booking.
Bottom Line
For domestic India last-minute: almost always compare two one-ways, ideally across different carriers. You'll frequently find the split is cheaper. For international last-minute: check the round-trip first; the bundled price sometimes wins. Either way, run the actual comparison rather than assuming one format is cheaper — the price difference on last-minute tickets is large enough that it's worth 5 minutes of checking.

Frequently asked questions
Is a one-way flight more expensive than a round-trip in India?
On domestic routes, one-ways are priced independently — there's no round-trip discount on Indian LCCs. Last-minute, two one-ways frequently sum to less than a round-trip because you can pick the cheapest carrier for each leg separately. On international routes, full-service airlines sometimes bundle return fares at a discount, so the round-trip can win.
Which is better last-minute: IndiGo or Air India for a round-trip?
It depends on the route and exact timing. IndiGo typically has the most inventory on trunk domestic routes, so it often has the cheapest last-minute one-ways — but not always. Air India's full-service fare may have better change flexibility, which matters if the return is uncertain. Price both on the same search rather than assuming one is cheaper.
Can I book two separate one-ways on the same airline and get a return fare?
You can try, but Indian airlines don't typically offer a 'return fare' for two separately booked one-ways — that discount, when it exists, only shows up when you select the round-trip option in a single search. Booking two one-ways on the same airline at the same time via the round-trip option is worth trying before splitting across carriers.
What's the risk of booking two separate one-ways for a last-minute trip?
The main risk is that if your outbound flight is delayed or cancelled and you miss your return, the return ticket is completely independent — the airline won't automatically rebook you or waive change fees because it was a separate booking. For last-minute travel when delays are possible, factor this in, especially during monsoon season when disruptions are more frequent.
Do OTAs charge extra fees on last-minute one-way tickets?
Yes — MakeMyTrip, EaseMyTrip, Goibibo, and most OTAs add a convenience fee per passenger per leg. On a last-minute one-way this is typically in the range of ₹200–600, sometimes higher. If you're booking two one-ways separately through OTAs, that fee applies twice. Booking direct on the airline's website avoids these fees.
Does SpiceJet still offer cheap last-minute flights in 2026?
SpiceJet operates a significantly reduced schedule as of 2026 and has had operational challenges. When it shows cheap fares, they can be tempting, but check recent reviews on cancellation and delay frequency for that route before booking for time-sensitive travel. IndiGo and Air India Express are more reliable options when timing matters.
