Airlines flying Kolkata to Guwahati
IndiGo leads with ≈ 5–7 daily non-stops on this short hop. Air India adds a few services, and SpiceJet and Akasa Air fill in additional slots. Some services use ATR 72 turboprops while most run A320 jets. Block time is ≈ 1h 20m — barely enough for a cup of tea. Guwahati also serves as a connecting point for onward flights to Dibrugarh, Jorhat, Imphal and other northeast destinations.
Cheapest time to fly and book
Demand surges during Bihu (April and January), Durga Puja (October) and the December holiday season when the northeast diaspora in Kolkata heads home. Monsoon months (June–August) see mixed demand — heavy rain deters tourists but homebound travellers keep loads decent. Booking 1–3 weeks ahead on this short sector usually secures competitive pricing.
Flight duration and routing
The non-stop covers ≈ 590 km in roughly 1 hour 20 minutes, flying northeast across the narrow Siliguri corridor. On such a short sector, connecting itineraries make no practical sense. Some passengers use Guwahati as a transit point for further northeast travel — if connecting to Imphal or Dibrugarh, allow at least 2 hours between flights at GAU.
Baggage and fares
IndiGo, SpiceJet and Akasa Air sell checked bags separately on base fares; 15 kg is the standard domestic add-on. Air India includes 15–25 kg depending on class. Fares on this short route are generally modest, but festival-week pricing can double. Indicative fares are live on FlightGPT as of May 2026. Pre-booking baggage online is cheaper than paying at the airport counter.
Airports and terminals
Kolkata departures use the single terminal at CCU. Guwahati arrivals land at Lokpriya Gopinath Bordoloi International Airport (GAU), about 20 km west of the city centre in Borjhar. Prepaid taxis, Ola and city buses link GAU to Paltan Bazaar, Fancy Bazaar and the Kamakhya temple area in ≈ 30–45 minutes.
Do you need any documents?
No passport or visa is needed on this domestic route. A government photo ID (Aadhaar, voter ID, PAN, driving licence) is sufficient. Note that if you plan onward travel to Arunachal Pradesh, Nagaland or Mizoram from Guwahati, you may need an Inner Line Permit (ILP) — check before your trip.
