Delhi (DEL) to Guwahati (GAU) is the main air gateway between North India and the Northeast, and it is well served by non-stops. IndiGo flies it most frequently, with Air India, Air India Express and SpiceJet also operating directly. (Go First and Jet Airways no longer exist, and Vistara has merged into Air India.)
IndiGo and Air India use A320-family jets; SpiceJet and Air India Express fly Boeing 737s. With a dozen-plus daily departures you can pick a morning or evening non-stop. Connecting itineraries via Kolkata exist but add little value over the direct flights here.
The flight covers about 1,690 km and takes roughly 2h 20m–2h 40m in the air, tracking east across the Gangetic plain and over the lower Himalayas' foothills towards the Brahmaputra valley. It is one of the longer domestic non-stops, so it is worth choosing your seat and meal in advance.
Block time at Delhi can run longer in peak banks because of taxi and holding; Guwahati is quick on arrival.
This is a mix of business, government, defence and VFR traffic with strong festival peaks. Because it is a longer sector, last-minute fares rise sharply — book 4–6 weeks ahead for the best non-stop prices.
| Period | Demand | Fare pressure |
|---|---|---|
| Oct–Nov (Durga Puja / Diwali) | Very high | Highest of the year |
| Apr (Bihu) & Dec–Jan | High | Higher |
| May–Jun (summer holidays) | High | Higher |
| Feb–Mar, Jul–Sep | Moderate | Best value |

Early-morning departures from Delhi tend to be the most punctual and get you into Guwahati with the day ahead — useful if you are connecting onward to other Northeastern states by road or smaller flights. In December–January, Delhi morning fog can delay the first wave, so a mid-morning slot can paradoxically be more reliable in deep winter. Evening flights suit a full working day in Delhi first.
Business and government travellers: a morning non-stop allows meetings the same afternoon in Guwahati. IndiGo and Air India have the fullest schedules for rebooking. On the longer block time, a paid seat and meal are worth it.
Families: this is a 2.5-hour flight, so pack entertainment and snacks for children. Choose a daytime departure, book seats together early, and note that Guwahati is a quick, manageable arrival.
Students and budget travellers: book several weeks ahead, fly mid-week and travel cabin-only on the lowest fare. Compare SpiceJet and Air India Express against IndiGo for the cheapest seat.
Delhi (DEL) — Indira Gandhi International: low-cost carriers (IndiGo, SpiceJet, Air India Express) use Terminal 1 or Terminal 2, while Air India uses Terminal 3. The terminals are far apart and an inter-terminal transfer takes time, so check your terminal carefully before you travel.
Guwahati (GAU) — Lokpriya Gopinath Bordoloi International: a single integrated terminal handling all flights. It is the busiest airport in the Northeast and the gateway to Assam, Meghalaya and beyond.
Delhi: IGI is well connected by the Airport Express Metro (to T3), the Delhi Metro, app cabs and pre-paid taxis. Allow extra time at peak hours and for inter-terminal transfers.
Guwahati: the airport (Borjhar) is about 20–25 km west of the city centre, a 45–60 minute drive depending on traffic. App cabs, pre-paid taxis and shared cabs serve the city; this is also the launch point for onward travel to Shillong, Kaziranga and other Northeastern destinations.
Domestic economy typically allows 15 kg checked plus 7 kg cabin, though the lowest 'lite' fares may be cabin-only. SpiceJet and Air India Express have their own specifics. Check the live rules on IndiGo baggage and SpiceJet baggage, and weigh your bag at home to avoid excess charges.
No visa — this is a domestic flight within India, and no Inner Line Permit is needed for Assam/Guwahati. You only need a valid government photo ID matching your ticket name. (Note that some other Northeastern states, such as Arunachal Pradesh, Nagaland, Mizoram and Manipur, do require an ILP — but not Assam.)
The Northeast monsoon is long and heavy (roughly May–September), bringing rain that can delay Guwahati arrivals; the dry, pleasant season runs October to March. Delhi adds winter fog (Dec–Jan) that disrupts early-morning departures. For the best experience — and to combine Guwahati with Kaziranga or the rest of Assam — travel between November and March. Book a buffer if you have onward connections by road into the hills.
Guwahati is the only high-frequency trunk into the Northeast, so if it is a stop en route to Shillong, Kaziranga or Tawang, book the Delhi leg early — seats tighten sharply around Bihu (mid-April) and the October–November festival and Kaziranga reopening window. Aim for a morning Delhi departure: it gives you the full day to make the onward road or shared-sumo connection from Guwahati, and those counters thin out by evening. If you are heading on to Arunachal Pradesh, sort your Inner Line Permit before you fly — it is checked on arrival there, not at Guwahati.
Guwahati is the cultural and commercial heart of the Northeast — home to the Kamakhya temple, the mighty Brahmaputra and Umananda island. It is also the springboard for Kaziranga's one-horned rhinos, the living-root bridges of Meghalaya and the hills of Shillong. For most travellers heading into the seven sister states, a Delhi–Guwahati flight is the first leg of the journey.
About 2h 20m to 2h 40m non-stop over roughly 1,690 km — one of the longer domestic sectors.
IndiGo, Air India, Air India Express and SpiceJet operate non-stops, with IndiGo the most frequent.
Around 12–18 non-stops a day across all carriers, varying by day and season.
Low-cost carriers use Terminal 1 or 2; Air India uses Terminal 3. The terminals are far apart, so check your ticket before travelling.
No, Guwahati (GAU) has a single integrated terminal handling all flights.
No. Assam and Guwahati do not require an ILP. Some other Northeastern states (Arunachal Pradesh, Nagaland, Mizoram, Manipur) do, but not Assam.
Roughly 4–6 weeks ahead and mid-week. Avoid Durga Puja/Diwali (Oct–Nov) and Bihu (mid-April) for the lowest fares.
Usually 15 kg checked plus 7 kg cabin in economy, though 'lite' fares may be cabin-only. Check your airline's current rules before flying.
Yes, all the airlines open web check-in around 48 hours before departure — handy at busy Delhi terminals.
Yes. Under DGCA rules, an airline cancellation entitles you to a full refund or a free alternative flight.
Delhi sees winter fog (Dec–Jan) that delays morning flights, and the Northeast monsoon (May–Sep) can delay Guwahati arrivals. Build in buffer time.
Pet policies vary by airline and need advance booking; not every carrier accepts pets in the cabin. Confirm directly with your airline.
Yes. Infants under two travel as lap passengers for a nominal fare plus taxes. Carry age proof and request a bassinet seat where available.
Compare both. Booking direct simplifies refunds and changes; FlightGPT lets you compare fares across sources to find the best price.
