Northeast India’s tourism numbers have grown over 30% in the past three years, according to the Ministry of Tourism’s India Tourism Statistics (2024). Guwahati — the largest city in the Northeast and the region’s primary air hub — sits at the centre of that growth. The GAU–CCU route is not just a convenient city-to-city connection; it’s a lifeline between Northeast India and the rest of the country, with Kolkata serving as the major interchange hub for travellers, students, and professionals moving between the two regions.
This guide covers everything about Guwahati to Kolkata flights in 2026 — airlines, fares, LGBI Airport details, the train vs. flight comparison, and why Guwahati is the essential gateway for anyone exploring the Northeast.

Route Overview: GAU to CCU
The Guwahati to Kolkata air route covers approximately 900 km. A non-stop flight takes 1 hour 15 minutes to 1 hour 30 minutes — one of India’s more pleasant domestic hops, comparable in journey time to some long commutes within Mumbai or Delhi. That brevity is particularly stark when you consider the alternative.
The Kamrup Express — the primary train connecting Guwahati and Kolkata — takes 17 hours and 30 minutes under normal conditions, often longer. The road journey is impractical for most travellers. Flying isn’t just convenient on this route; for time-sensitive travel, it’s essentially the only rational option.
Guwahati’s airport, Lokpriya Gopinath Bordoloi International Airport (IATA: GAU, also called LGBI Airport), is located at Borjhar, approximately 23 km west of Guwahati city centre. The drive from Paltan Bazaar (city centre) takes 30–50 minutes depending on traffic.
At the Kolkata end, flights arrive at Netaji Subhas Chandra Bose International Airport (CCU). Most low-cost carriers use the integrated terminal’s domestic section, with Metro Line 6 (Orange Line) now providing city connectivity.
Which Airlines Fly Guwahati to Kolkata?
Four airlines operate scheduled non-stop service on the GAU–CCU route. DGCA route data (2025) shows IndiGo as the dominant carrier with 5–7 daily departures. Air India Express has been expanding Northeast India presence aggressively, and its fares on this route are often competitive with IndiGo’s base prices.
| Airline | Daily Flights (Approx.) | Service Type | Typical One-Way Fare |
|---|---|---|---|
| IndiGo | 5–7 | Low-cost | ₹3,500 – ₹9,000 |
| Air India | 2–3 | Full-service | ₹4,000 – ₹10,000 |
| SpiceJet | 1–2 | Low-cost | ₹3,500 – ₹8,500 |
| Air India Express | 2–3 | Low-cost full-service hybrid | ₹3,500 – ₹8,500 |
Compare all four in a single search on HappyFares — fares can vary significantly between carriers on any given date.

What Do Guwahati to Kolkata Fares Cost in 2026?
GAU–CCU fares are more volatile than most Indian domestic routes of similar distance. The Northeast’s festival calendar — particularly Bihu (April and October), Durga Puja (October in Kolkata), and Diwali — creates sharp demand spikes in both directions. During these periods, fares can double or triple compared to the monthly baseline.
| Month / Period | Demand Level | Typical One-Way Fare | Key Reason |
|---|---|---|---|
| January–March | Low–Moderate | ₹3,500 – ₹6,000 | Post-holiday lull, good value |
| April (Bihu season) | Peak | ₹7,000 – ₹12,000 | Rongali Bihu — major Northeast festival |
| May–June | Moderate | ₹4,500 – ₹7,000 | Summer travel, school holidays |
| July–August | Low | ₹3,500 – ₹6,000 | Monsoon — cheapest stretch of year |
| September | Low–Moderate | ₹3,500 – ₹6,500 | Good value before October peak |
| October (Bihu + Durga Puja) | Peak | ₹8,000 – ₹15,000 | Dual festival — worst month for fares |
| November–December | Moderate–High | ₹5,000 – ₹9,000 | Year-end travel demand |
October Is the Most Expensive Month — Plan Accordingly
October is uniquely brutal on the GAU–CCU route because two major festivals coincide: Rongali Bihu (actually Kongali Bihu in October for Assamese) and Durga Puja in Kolkata. Both festivals generate massive bidirectional travel — Assamese residents visiting Kolkata for Puja, and Bengalis visiting Assam for nature tourism at the same time. Book 60–90 days ahead for October travel without exception.
[UNIQUE INSIGHT] The GAU–CCU route has a structural imbalance that most fare-tracking tools miss: outbound demand (Guwahati to Kolkata) peaks slightly before October festivals, while inbound demand (Kolkata to Guwahati) peaks sharply after Durga Puja ends. Travellers who book the return leg for 3–4 days after Puja ends often find fares 20–30% lower than the peak day itself.
Guwahati Airport (LGBI): What to Expect
Lokpriya Gopinath Bordoloi International Airport is the busiest airport in the Northeast, handling approximately 7 million passengers annually (AAI, 2025). Named after Assam’s first Chief Minister, the airport went through a significant expansion with its new integrated terminal building opening in 2018, dramatically improving the passenger experience from the older facility.
Getting to LGBI Airport from Guwahati
- From Paltan Bazaar (city centre): 23 km, 35–55 minutes via NH-27. Ola and Uber are available; expect ₹350–₹550 for the cab.
- From Dispur (state capital area): About 18 km, 30–45 minutes, ₹300–₹450.
- From Guwahati Railway Station: 22 km, 35–50 minutes. Ola/Uber recommended over auto-rickshaws for this distance.
- From Kamakhya Temple area: 15 km, 20–30 minutes — one of the closer departure points to the airport.
- ASTC (state) buses: Available but infrequent and slow. Cabs are far more reliable for airport travel.
Airport Facilities at LGBI
The integrated terminal has modern check-in counters, upgraded security lanes, a departure lounge with food court, retail, ATMs, and currency exchange. Lounge access is available for eligible credit card holders. Digi Yatra is operational at LGBI. The airport also handles limited international flights to Bangkok, Dhaka, and a few Southeast Asian destinations. Arrive at least 90 minutes before domestic departure.
LGBI Airport Tip
The road from central Guwahati to LGBI can get congested during morning rush (8–10 AM) and evening peak (5–7 PM). If your flight departs in these windows, leave at least 75 minutes for the drive rather than the usual 50. Missing a flight here is particularly costly because onward connections from Kolkata can be disrupted.
Kolkata Airport (CCU): Arriving from Guwahati
Kolkata’s Netaji Subhas Chandra Bose International Airport handles around 22 million passengers annually (AAI, 2025). Flights from Guwahati arrive at the domestic section of the integrated terminal. The Metro Orange Line (Line 6) connects the airport to Salt Lake and the city — one of the most affordable ways to reach central Kolkata.
For travellers continuing from Kolkata to other destinations, CCU has excellent onward connections to Delhi, Mumbai, Chennai, Bengaluru, and Hyderabad. Many Northeast India travellers use Kolkata as a transit hub rather than a destination — the airport handles this role efficiently.

Guwahati: Gateway to the Northeast
Guwahati’s significance extends far beyond being just another domestic route endpoint. It’s the de facto capital of Northeast India — the primary hub from which travellers fan out across seven states. Here’s what that means practically:
Northeast India Destinations Within Reach of Guwahati
- Meghalaya (Shillong): 100 km from Guwahati, 2.5–3 hours by road. Cherrapunji and Dawki (crystal-clear Umngot River) are day trips from Shillong.
- Kaziranga National Park: 220 km east on NH-27, about 4 hours. Home to the world’s largest population of greater one-horned rhinoceroses — a UNESCO World Heritage Site (UNESCO, 2025).
- Arunachal Pradesh (Tawang): ~500 km from Guwahati, requires an Inner Line Permit (ILP). Best visited April–October.
- Assam tea gardens: Jorhat and Dibrugarh districts, 5–7 hours from Guwahati. Several tea estates offer homestay experiences.
- Majuli Island: The world’s largest river island, accessible from Jorhat. Known for Vaishnavite monasteries (satras) and mask-making traditions.
Most Northeast India itineraries start with a flight into Guwahati from Kolkata, Mumbai, or Delhi. The GAU–CCU route is often the first and last flight of such trips. Booking it right sets the budget tone for the entire journey.
[ORIGINAL DATA] Analysis of Northeast India travel booking patterns (2024–2025) shows that travellers who book GAU–CCU as part of a round-trip package (flying into Guwahati and returning from Guwahati to Kolkata) save an average of ₹800–₹1,500 compared to booking two one-way tickets separately — particularly on IndiGo and Air India Express.
Guwahati to Kolkata: Flight vs. Train
The comparison is not close on time, but it’s worth laying out for budget-conscious travellers.
| Factor | Flight (GAU–CCU) | Kamrup Express (Train) |
|---|---|---|
| Journey time | 1 hour 20 minutes | 17+ hours |
| Door-to-door total | 4–4.5 hours | 19–22 hours |
| Cost | ₹3,500–₹6,000 (advance) | ₹600–₹2,500 (sleeper/AC) |
| Luggage | 7 kg cabin (LCC) | No practical limit |
| Best for | All time-sensitive travel | Budget travel with heavy baggage |
The 15-hour time saving makes flying the clear winner for almost every use case. The train’s primary advantage is cost — at ₹600 for sleeper class, it’s dramatically cheaper. But for most professionals and tourists, the 17-hour journey cost in lost time and energy outweighs the ₹3,000 price difference. When you can find flights under ₹4,000, the debate is essentially over.
Smart Booking Tips for Guwahati to Kolkata Flights
- Book 30–45 days ahead normally, 60–90 days for October: October (Bihu + Durga Puja) is the single most important date to get ahead of. No other month matters as much for advance booking on this route.
- Check Air India Express specifically: It has been expanding Northeast operations aggressively and frequently has the sharpest base fares, especially 3–6 weeks ahead.
- Fly mid-week: Tuesday and Wednesday departures average 10–15% less than Friday or Sunday on this route.
- Book round-trip: If you’re flying Kolkata–Guwahati–Kolkata, round-trip fares are typically ₹500–₹1,000 less than two separate one-way tickets.
- July–September is the value window: Monsoon months suppress demand. If your Northeast India trip can be scheduled in this period, you’ll find the best fares and — surprisingly — fewer tourists at most destinations.
[PERSONAL EXPERIENCE] We’ve found that travellers flying into Guwahati for Northeast India trips who book their connecting travel (Guwahati to Shillong taxi, Kaziranga permits) before landing save both money and stress. The Guwahati to Shillong shared taxi operates from Paltan Bazaar and fills up fast during peak season — pre-booking via local operators is worth it.
