Northeast India is one of India's last great under-touristed frontiers — and airfares, when you catch them right, reflect that. IndiGo and Air India Express run ₹2,500–₹4,500 advance fares into Guwahati. Imphal and Dibrugarh are thinner routes with fewer seats, which means date flexibility and early booking matter even more. AI search handles this complexity well.
TL;DR — the short answer
The cheapest flights to Northeast India — Guwahati (GAU), Imphal (IMF) and Dibrugarh (DIB) — typically fall in the ₹2,500–₹5,000 one-way range when booked 3–6 weeks ahead on IndiGo or Air India Express. Guwahati is the best-connected hub and easiest to find deals on. Imphal and Dibrugarh have fewer seats and less carrier competition, so date flexibility through an AI tool like FlightGPT matters considerably more.
Which airlines fly to Guwahati, Imphal and Dibrugarh?
Let me lay out the realistic 2026 carrier landscape for each city:
- Guwahati (GAU — Lokpriya Gopinath Bordoloi International): The Northeast hub. IndiGo and Air India operate the most frequent services from Delhi, Mumbai, Kolkata and Bangalore. Air India Express serves some routes. Akasa Air has been expanding into Northeast India. SpiceJet operates GAU but has had reliability issues — check operating status before booking. Fares from Delhi in the ₹3,000–₹6,000 range in advance are common.
- Imphal (IMF — Bir Tikendrajit International): Served primarily by IndiGo and Air India from Guwahati, Kolkata and Delhi. Fewer seats overall means prices firm up faster. Imphal–Guwahati short hops can be under ₹2,500 advance; Imphal–Delhi is typically ₹4,000–₹8,000 advance depending on date.
- Dibrugarh (DIB — Dibrugarh Airport): IndiGo is the main carrier. Connecting routes typically go via Guwahati or Kolkata. Non-stop from Delhi on IndiGo exists but frequency is limited — often 1–2 daily. Advance fares DIB–Delhi can be ₹3,500–₹7,000 one-way. Closer to departure on high-demand dates, prices jump considerably.
Note: Go First and Jet Airways are defunct — if any OTA is still showing their routes as bookable, that data is stale. Vistara merged into Air India in 2024; what you see now on those routes is under the Air India brand.
The single-operator problem and how AI helps
The Northeast's aviation challenge is thin route competition. Some city pairs — say, Imphal–Shillong or smaller Assam airports like Jorhat or Silchar — have only one or two daily flights on a single carrier. When that is the situation, there is no meaningful price competition and fares do not drop the way they do on IndiGo-vs-IndiGo-vs-Air-India routes.
Lakshadweep is the extreme case: Agatti (AGX) receives effectively one carrier's flights (historically Air India / Alliance Air / now Air India), and prices reflect the lack of alternatives. The same logic applies, to a lesser degree, to remote Northeast airports.
What AI search does well in this scenario: it finds the date and time combinations where even limited seat inventory is priced lower — airlines typically open seats in fare buckets, and early-week departures or mid-month dates on these thin routes can be ₹2,000–₹4,000 cheaper than weekend or month-end departures. FlightGPT lets you search across a date range in plain language: 'What is the cheapest week to fly Delhi to Dibrugarh in August?'
AI date-flex strategy for Northeast routes
I have booked the Northeast circuit a few times now — Guwahati in, Dibrugarh out, or vice versa — and the date flexibility play is where I consistently find the savings. Some practical patterns:
- Midweek departures: Tuesday and Wednesday flights out of Delhi to Guwahati tend to be priced lower than Friday and Sunday departures. The ₹1,500–₹2,500 gap between peak-day and midweek on the same airline is real and consistent.
- 3–5 week advance window: Northeast fares — especially Guwahati — tend to price reasonably in the 3–5 week window. Inside 2 weeks and outside 8 weeks, prices are less predictable. Set a FlightGPT alert or check every few days during the optimal window.
- Avoid Bihu and Durga Puja dates: Rongali Bihu (April), Bohag Bihu and especially Durga Puja (October) are high-demand dates for Northeast flights from the rest of India. Book 6–8 weeks out minimum for these periods; last-minute prices can be 2–3x the normal range.
- Guwahati as transit hub: If your destination is Imphal, Shillong (SHL), Jorhat or Silchar, price the journey as Anywhere–Guwahati + Guwahati–Final destination separately. It is often cheaper to book two tickets than a single connecting itinerary priced as one, especially if you can overnight in Guwahati.
Getting to the smaller Northeast airports cheaply
Beyond GAU, IMF and DIB, the Northeast has airports at Jorhat, Silchar, Shillong, Tezpur, Lengpui (Aizawl) and Agartala. For most of these, the routing is: major city → Guwahati (or Kolkata) → smaller airport. The trick is that the Guwahati–onward sector is often short (30–60 minutes) but priced disproportionately high because of limited competition.
Air India has historically been the primary operator on some of these thinner government-mandated routes under the UDAN regional connectivity scheme. UDAN-designated routes have capped fares (the scheme specifies a maximum fare per route), which can make them surprisingly affordable. Worth checking: the UDAN scheme airport list on the Civil Aviation Ministry website to see if your specific route is covered — if it is, a capped-fare seat could be significantly cheaper than the open-market alternative.

Bottom line for Northeast India backpackers
Northeast India rewards the flexible traveller. The dates are negotiable, the routes are thin and the savings from flexibility — midweek, 3–5 weeks ahead, Guwahati as a split booking hub — genuinely add up to ₹3,000–₹6,000 per return trip compared to booking whatever is convenient. For a backpacker budget, that is two or three days of accommodation.

Frequently asked questions
What is the cheapest flight to Guwahati from Delhi in 2026?
On advance booking (3–5 weeks out) on IndiGo or Air India, Delhi–Guwahati fares are often in the ₹3,000–₹5,500 one-way range for economy. Midweek departures (Tuesday, Wednesday) tend to be lower. Peak Bihu and Durga Puja dates see prices jump significantly — book 6–8 weeks out for those periods.
Which airline flies to Imphal (IMF) from Delhi?
IndiGo and Air India both operate Delhi–Imphal, typically with a Guwahati connection though non-stop services exist. Fares on the Delhi–Imphal sector range from around ₹4,000–₹9,000 one-way depending on how far in advance you book and the date. Seat inventory is limited, so booking earlier than you would for a busier route is wise.
Are UDAN scheme flights available for Northeast India routes?
Yes — several Northeast routes are covered under the Government of India's UDAN regional connectivity scheme, which caps fares on designated route/seat blocks. Air India operates some of these. Check the Civil Aviation Ministry's UDAN portal for the current list of covered routes and participating airlines, as route coverage changes with each scheme round.
Is it cheaper to book two separate tickets (e.g., Delhi–Guwahati + Guwahati–Imphal) than a connecting itinerary?
Often yes — split bookings into Guwahati hub can save ₹1,500–₹4,000 on the total fare versus a single-ticket connection priced by an OTA. The trade-off is that if the first flight is delayed and you miss the second, the two airlines owe you nothing for the missed sector. Allow at least 3–4 hours between sectors in Guwahati to mitigate this risk.
What is the best time of year to find cheap Northeast India flights?
Off-peak months — roughly February–March and June–July (excluding major festival windows) — tend to offer the best fares to Northeast India. October (Durga Puja) and April (Bihu season) are the highest-demand periods. January has the bonus of pleasant weather and moderate fares, making it a sweet spot for tourism.
