Kolkata to Hanoi flights — quick facts

Airlines flying Kolkata to Hanoi

Kolkata's relatively short distance to Hanoi has supported occasional non-stop service from low-cost carriers such as Vietjet and IndiGo, though availability is seasonal – check live before you plan around it. When no non-stop suits your dates, the common 1-stop routings go via Bangkok (Thai AirAsia, Vietjet, IndiGo) or Kuala Lumpur (AirAsia, Malaysia Airlines), with onward connections to Hanoi. Vietnam Airlines also serves HAN from regional hubs. Through-fares and self-transfer combinations both appear on FlightGPT – compare the total price against the layover. Always verify live schedules on the official airline site before booking.

Cheapest time to fly & book

Fares to Hanoi from Kolkata usually soften outside the December–January and mid-year holiday peaks, with shoulder months – roughly March to May and September to November – offering better value. Hanoi's pleasant autumn (around October–November) is popular, so book those dates earlier. If a non-stop is running, it often prices competitively against 1-stop fares, so compare both. Mid-week departures tend to be cheaper, and overnight Bangkok connections can cut costs. Indicative fares are live on FlightGPT (fares as of May 2026); set a price alert and watch for seasonal non-stop launches that can undercut connecting options.

Flight duration & routing

A non-stop, when available, covers the ≈ 2,200 km in roughly 4 hours. With a connection, total travel time is typically ≈ 6–8 hours including the layover. Via Bangkok, the Kolkata→BKK leg is around 2h 30m, followed by a ~2-hour BKK→HAN sector plus connection time; a KL routing is a little longer. A through-ticket protects the connection and tags bags to Hanoi; a self-transfer saves money but you reclaim and re-check bags at the hub, so allow a buffer. Hanoi is 1h 30m ahead of IST, so timings shift only slightly.

Baggage & fares

Allowances depend on the carrier and fare bundle. Low-cost airlines such as Vietjet, IndiGo and Thai AirAsia sell lean base fares, with checked baggage (commonly 15–30 kg) added separately – buy it online in advance, as airport rates are much higher. Vietnam Airlines and Malaysia Airlines usually include checked plus cabin baggage. On self-transfer itineraries, confirm whether bags route through to Hanoi or must be collected at the hub.

Airports & terminals

You depart from Netaji Subhas Chandra Bose International Airport, Kolkata (CCU), whose integrated terminal handles international flights – arrive about three hours early. Connections route through Bangkok Suvarnabhumi (BKK) or Don Mueang (DMK) – note Thai AirAsia and Vietjet often use DMK – or Kuala Lumpur (klia/klia2). If a connection switches Bangkok airports (BKK vs DMK), that requires a city transfer, so check carefully. Hanoi's Noi Bai International Airport (HAN) has separate domestic and international terminals (T1 and T2); international arrivals use T2, about 27 km from the Old Quarter by taxi or shuttle bus.

Documents needed / entry rules

Indian passport holders need a valid passport (six months' validity recommended) and a Vietnam e-visa for tourism, applied for online via the official Vietnam Immigration portal before travel – allow several working days for processing and print your approval. Vietnam's e-visa is commonly issued for single or multiple entry; check the current validity and conditions when you apply. Carry onward/return tickets, proof of accommodation and sufficient funds. Avoid unofficial visa agents charging inflated fees. Always verify live entry requirements on the official Vietnamese immigration and embassy sites, as rules and fees can change at short notice.
