Kolkata's NSCBI airport (CCU) has the most distinctive eastward international map in India — Bangkok, Dhaka, Kathmandu, Yangon and the iconic Drukair Paro route make it eastern India's structural gateway.
Quick answer
From Netaji Subhas Chandra Bose International Airport (CCU) in Kolkata in 2026 you can fly direct to Bangkok (BKK), Dhaka (DAC), Kathmandu (KTM), Yangon (RGN), Paro (PBH) on Drukair, Singapore (SIN), Kuala Lumpur (KUL), Dubai (DXB), Sharjah (SHJ), Doha (DOH), Hong Kong (HKG on certain cycles), Guangzhou (CAN on certain cycles), Colombo (CMB) and Male (MLE). CCU is structurally eastern India's primary international gateway, with the most distinctive eastward route map in India — the Bhutan (Paro), Bangladesh (Dhaka), Nepal (Kathmandu) and Myanmar (Yangon) direct routes are essentially unique to CCU among Indian airports.
The eastward international map and what it means
CCU's 2026 international slate is structurally unique. The Bhutan direct route on Drukair (KB) — Kolkata to Paro — is one of the few Drukair operations into India and is a critical link for Indian tourism into Bhutan and for Bhutanese travellers into India. Paro Airport (PBH) is one of the world's most operationally challenging airports — the approach through Himalayan terrain requires specially-trained pilots — and the Drukair operation is the structural way for most Indian travellers to reach Bhutan.
The Bangladesh direct routes — Kolkata to Dhaka, operated by Biman Bangladesh Airlines (BG), US-Bangla Airlines and Air India Express on certain cycles — are critical bilateral connectivity for eastern India. The Nepal direct routes — Kolkata to Kathmandu, operated by IndiGo, Nepal Airlines and others — anchor the eastern India-Nepal connection. The Myanmar direct route to Yangon is operated by Myanmar Airways International (MAI) and IndiGo on selected cycles.
For broader Southeast Asia — Bangkok is the deepest route, with Thai Airways (TG), IndiGo, Vistara/Air India (post-merger) and others operating. Kuala Lumpur is operated by Malaysia Airlines and AirAsia. Singapore by Singapore Airlines and IndiGo. For the Gulf, Emirates, Qatar Airways, IndiGo, Air India Express and the major Gulf carriers operate the standard hub routes. For Hong Kong and southern China, the routes have been on-and-off through the post-pandemic cycle.
What is missing in 2026 — no direct Europe (some cycles have seen Lufthansa and BA, but year-round Europe direct has been variable), no direct US, no direct East Asia long-haul (Japan, Korea). The Europe and US plays are via Gulf hubs or via Singapore.
Terminal experience and the AAI-operated reality
CCU is operated by AAI (Airports Authority of India) directly — one of the few major Indian airports still under direct AAI operation rather than concessioned to Adani, GMR or a similar private operator. The integrated terminal (Terminal 1, with separate international and domestic concourses) was substantially expanded in the 2013 commissioning of the new terminal and has been progressively refreshed. Capacity is in the 25 to 30 million passenger range and AAI passenger volumes at CCU run roughly in the 20 to 24 million range.
The terminal experience is functional and meaningfully better than the older airport. The international arrivals immigration hall and the baggage belt capacity were improvements in the 2013 expansion that have held up reasonably. The international departures airside is spacious with multiple boarding gates clustered for narrow-body and a smaller cluster for widebody.
The runway is 19R/01L (the primary), 3,627 metres long with ILS approaches. This is comfortably sufficient for B787, B777, A330 and A350 widebody operations to anywhere relevant in the international network. A380 has operated CCU on occasional Emirates schedules.
The Drukair Paro route — operational notes
The Kolkata to Paro Drukair (KB) route deserves its own section because of the operational specificity. Paro Airport (PBH) sits in a valley in western Bhutan at roughly 2,235 metres elevation. The approach requires aircraft to navigate Himalayan terrain on a visual approach (Paro is one of the few major airports in the world without a standard instrument approach procedure for commercial operations), and only a small set of specially-trained Drukair and Bhutan Airlines pilots are authorised for the operation.
The practical implications for passengers — flights operate only during daylight hours, weather minima are strict (overcast or poor visibility cancels), and schedule changes due to weather are routine. For Indian tourists heading to Bhutan, the realistic move is to build flexibility into the itinerary. Drukair's CCU-PBH operates on narrow-body A319 metal and is typically a daily or near-daily service.
The other Indian airports with direct Paro service are Delhi (DEL) on certain cycles, Guwahati (GAU) on selected schedules and Bagdogra (IXB) on selected schedules. For most Indian tourists, the CCU-PBH route is the structural default.
Lounges and food at CCU
The flagship lounge at CCU is the Plaza Premium Lounge at international airside, accessible via DreamFolks visits and Priority Pass. Walk-in pricing is roughly 2,000 to 2,400 rupees. The food spread has a Bengali nod — proper luchi-cholar dal, kosha mangsho, fish curry and the standard Bengali staples on certain days, alongside the standard hot Indian veg and non-veg, continental and tea-coffee bar. The Air India Maharaja Lounge serves AI business and first class plus Star Alliance Gold on AI metal. Contract lounges for Emirates, Qatar Airways, Thai Airways and Singapore Airlines serve their respective premium passengers.
Airside food at CCU has a strong Bengali presence — proper kathi rolls (Nizam-style), mutton biryani, fish fry, mishti doi at the regional counters, alongside the standard chain options. The Flury's outlet (a Kolkata institution) operates a concession at the airport on certain cycles — worth the stop for the rum balls and pastries. For a quick chai-and-snack stop before a 2 a.m. Gulf departure, the 24x7 chai counter is reliable.
Self-connect strategy for eastern India
For eastern India travellers — West Bengal, Bihar, Jharkhand, Odisha (partially, with BBI also viable), Assam (with GAU also viable), Sikkim, the Northeast — CCU is the structural international hub for any destination not directly served from a regional Tier-2 airport. The deep BKK and Drukair PBH routes are essentially unique. The Dhaka, Kathmandu and Yangon connectivity is critical for cross-border travel.
For Europe — via Gulf hubs (DOH on QR, DXB on EK, AUH on EY) is the cleanest. For US — via Gulf hubs is the structural play. For East Asia (Japan, Korea, Greater China) — via Bangkok on Thai or via Singapore on SQ, or via HKG on partner connections.
For Bihar, Jharkhand, Odisha and the Northeast catchment — CCU is the primary international gateway. For BBI-area Odisha travellers, the local BBI international routes serve Gulf, BKK and CMB directly. For Guwahati-area Northeast travellers, GAU has its own growing international slate (Dubai, Bangkok, Singapore on certain cycles) — see Guwahati GAU.
Ground access and overnight stays
CCU sits roughly 17 km north of central Kolkata (Park Street, Esplanade) and 20 km from Salt Lake's IT sector. Pre-paid taxi is typically 350 to 550 rupees and 35 to 60 minutes outside peak. Uber and Ola operate from designated zones. Kolkata Metro extension to the airport (the Noapara-Barasat Line) is in advanced construction with phased commissioning expected through the 2026-2027 window. Once commissioned, the metro will materially improve airport access predictability.
For overnight stays before an early-morning international departure, the JW Marriott Kolkata, the Hyatt Regency Kolkata, the Westin Kolkata Rajarhat, the Lalit Great Eastern, the Park Hotel Kolkata and several mid-tier Lemon Tree, ibis and Holiday Inn properties offer reliable options. The Holiday Inn Kolkata Airport is the closest premium option to CCU.
