Rupsi Airport has a stop-start history. A wartime airfield turned civilian, it reopened under the UDAN regional scheme with Flybig, which pulled out on 07 Nov, 2023. After nearly a year without flights, Alliance Air restarted services in October 2024, linking Rupsi with Kolkata and Guwahati using a 72-seat ATR 72. The schedule began at three flights a week, initially on Tuesdays, Thursdays and Saturdays, and listings in 2026 still show about three weekly Kolkata departures. Days can change between seasons, so check FlightGPT for your travel week.
The Kolkata departure leaves around 07:05 in recent schedules, so plan an early start. Flying time on the ATR is about 1 hour 30 minutes over 415 km, heading north-east across north Bengal and the Bangladesh border region into the Brahmaputra valley. Alliance Air operates the route as part of a Kolkata–Rupsi–Guwahati circuit, so the aircraft may continue to Guwahati after Rupsi. In the monsoon from June to September, low cloud and heavy rain over western Assam can cause delays. Winter mornings sometimes bring fog to Kolkata, which can hold early departures.
Kolkata's Netaji Subhas Chandra Bose International Airport uses a single integrated terminal. For a 07:05 flight, arrive by about 05:45; Alliance Air closes check-in 45 minutes before departure. A taxi from Esplanade or Park Street takes 30–40 minutes at that hour, and from Howrah station about 40–50 minutes. ATR flights often board from a remote stand by bus. Small regional services get called early to keep the circuit on time, so stay close to the gate once boarding is announced. Carry Aadhaar, a passport or a driving licence for security checks.
Rupsi Airport sits roughly 17 km north of Dhubri town, between Dhubri and Kokrajhar. It is a small terminal, so expect a quick exit but limited facilities. Taxis are not always waiting, so arrange a pick-up through your hotel or contacts. The drive into Dhubri takes about 30–40 minutes. Gauripur, home to the former royal estate, is closer, and Kokrajhar, headquarters of the Bodoland Territorial Region, is about an hour's drive. Bilasipara and Golakganj are also within reach, which makes Rupsi useful for the whole of lower western Assam.
Alliance Air lists your allowance with the fare. For domestic economy:
The ATR's bins are small, so expect wheeled cabin bags to be taken at the steps. Rupsi has a basic baggage area, and reclaim is usually quick. If you are travelling with medical equipment or bulky gifts for a family event in Dhubri, check with Alliance Air in advance, because weight limits can be tighter on short-runway regional operations.
Dhubri, on the Brahmaputra near the Bangladesh border, has strong historical ties with Bengal, and many families have relatives in Kolkata. Government officials, teachers and doctors posted in Dhubri and Kokrajhar districts use the flight for transfers and home visits. Visitors come to see the Gurudwara Sri Guru Tegh Bahadur Sahib, which commemorates the ninth Sikh Guru's visit, the old Panbari mosque, and the river ghats. Chakrashila Wildlife Sanctuary, known for golden langurs, lies between Dhubri and Kokrajhar. The flight saves roughly a full day on overland routes.
The ATR fills up around Durga Puja, Diwali, Bihu in mid-April and mid-January, Eid, and the Christmas–New Year break. The Guru Tegh Bahadur martyrdom observance in late November also draws Sikh pilgrims to the Dhubri gurudwara. With only about three flights a week and around 70 seats each, a busy week can sell out. Check FlightGPT several weeks ahead for holiday dates. If your plans change, remember there may not be another flight for two or three days. Our Dhubri to Kolkata guide covers the return trip.
On non-flying days, the options are longer. You can fly Kolkata to Guwahati, which has many daily non-stops, and drive west roughly 250–270 km to Dhubri, about six to seven hours. Bagdogra is another option, followed by a long road journey east through Cooch Behar. Trains from Howrah or Sealdah towards Assam stop at New Cooch Behar and New Bongaigaon, from where road links run to Dhubri. Compare the Rupsi non-stop against a Guwahati flight on FlightGPT; when the Rupsi flight operates, it is by far the quickest choice.
