Kolkata's Netaji Subhas Chandra Bose International Airport connects directly to Hanoi's Noi Bai International Airport on IndiGo's nonstop service, a relatively short international hop of about 2,260 km flown in roughly 2 hours 45 minutes. As of 2026 the route operates several departures a week rather than daily, reflecting Hanoi's growing but still developing popularity from eastern India. Because Kolkata sits geographically close to Southeast Asia, this is one of the quickest ways for Bengal travellers to reach Vietnam. Those planning a round trip will find the reverse Hanoi to Kolkata direction served on the same nonstop pattern, with comparable block times.
IndiGo is the carrier offering the nonstop, using its expanding international narrow-body network out of Kolkata to serve Hanoi. Full-service alternatives exist only as one-stop itineraries via hubs such as Bangkok, Singapore or Kuala Lumpur on carriers like Thai, Singapore Airlines, Vietnam Airlines or AirAsia, which add time and usually cost more. For the cleanest journey, IndiGo's direct flight is the default. As across all 2026 itineraries, note that Vistara no longer exists as a separate airline, having merged into Air India, so any legacy Vistara connection is now an Air India product. For pure speed from Kolkata, the IndiGo nonstop is hard to beat.
Indian passport holders need a visa to enter Vietnam, and the easiest route is the online e-visa, which in 2026 is available as a single or multiple-entry visa valid for up to 90 days and is processed entirely online without an embassy visit. You apply in advance, upload a passport scan and photo, pay the fee (commonly around USD 25 for single entry), and typically receive approval in roughly 3 to 7 working days, so apply at least a week or two before departure. Your passport must be valid for at least six months with blank pages. Full details and current rules are covered in our visa requirements guide before you book.
At about 2 hours 45 minutes of flying for the roughly 2,260 km, the Kolkata–Hanoi nonstop is comfortably shorter than most India-to-Southeast-Asia routes from the western metros. IndiGo operates the service on A320-family or A321 aircraft in an all-economy configuration, so set expectations for a no-frills narrow-body experience with buy-on-board catering. The short block time and the modest time difference (Vietnam is 1.5 hours ahead of India) make jet lag negligible. Because the route runs only a few times a week, build your wider itinerary around the available departure days rather than assuming daily flexibility, and arrive with margin for international check-in.
For the cheapest Kolkata–Hanoi fares, booking roughly one to three months ahead generally works well on an international route with limited frequency. The shoulder seasons of spring (March to April) and autumn (September to November) offer pleasant Hanoi weather and often softer fares than the December–January peak and the Indian festival travel surge. Northern Vietnam can be cool and misty in winter, so pack accordingly. Avoiding the Lunar New Year (Tet) window, when Vietnam itself travels heavily and prices and crowds spike, is wise. A fare alert is especially useful here given the route's non-daily schedule.
On IndiGo's international fares the included checked baggage is typically more generous than domestic, often around 20 kg or more depending on the fare and route, with a 7 kg cabin allowance, but always confirm the exact figure for your booking before paying. The cheapest fare buckets bundle less, so if you are bringing back shopping from Hanoi's Old Quarter, pre-purchasing extra baggage online is markedly cheaper than at the airport. Seat selection, meals and priority services are charged separately. Carry your e-visa printout, return ticket and hotel proof, as these can be checked at boarding and again on arrival at Noi Bai immigration.
Kolkata's Netaji Subhas Chandra Bose International Airport handles international departures from its integrated terminal, with the usual immigration and security flow, so allow the standard two-to-three-hour pre-departure margin for an international flight. Hanoi's Noi Bai International Airport, about 27 km north of the city, is a modern facility whose Terminal 2 handles international arrivals; expect straightforward e-visa immigration, ATMs and taxi or ride-hailing into the centre. The drive into Hanoi takes roughly 45 minutes to an hour depending on traffic. Both airports are well organised, making the door-to-door experience smooth for first-time Vietnam visitors from eastern India.
Hanoi is the springboard for northern Vietnam's headline experiences: the Old Quarter and Hoan Kiem Lake in the capital, the limestone seascape of Ha Long Bay a few hours away, and the terraced highlands of Sapa further north. Many Kolkata travellers pair Hanoi with a domestic Vietnamese hop to Da Nang or Ho Chi Minh City to see more of the country in one trip. Given the route's limited weekly frequency, lock your return date early.
