Kolkata is eastern India's grand old capital and a sharp launchpad into Asia — €139 to Bangkok, sub-€225 hops to Malaysia and Singapore, and a bag-included reach into Korea and Japan.
Netaji Subhas Chandra Bose International (CCU) has a brand-new advantage: the Kolkata Metro Orange Line (Line 6) now connects the airport directly into the city, accessible from inside the terminal. It reaches the centre (Esplanade) in 30–40 minutes for just ₹40, far beating a cab’s 40–60 minutes in Kolkata traffic. If you prefer road, prepaid taxis and app cabs are available, but the new metro is the clean, cheap, traffic-proof choice. From the central stations, the rest of Kolkata’s metro and the railways connect onward.
As a base, Kolkata’s value is its position as eastern India’s gateway — closer to Southeast Asia than the rest of the subcontinent, with cheap, frequent hops east.
Southeast Asia — closer from the east
Kolkata’s eastern position pays off here. Bangkok (€139) is the headline — Thailand’s capital for the price of a domestic Indian flight, a genuinely short hop from Bengal — with Kuala Lumpur (€220 with a bag) and Singapore (€223) opening Malaysia and the city-state. These are the impulse routes: cheap, quick and frequent, and noticeably closer (and cheaper) from Kolkata than from Delhi or Mumbai.
The Gulf and East Asia
The board reaches west and northeast. Abu Dhabi (€272) bridges to the Gulf and onward to Europe, reflecting the large Bengali workforce there. Northeast, Seoul (€412) and Tokyo (€428 with a bag) open South Korea and Japan — strong fares for the distance, several with luggage. From an eastern Indian hub these turn Kolkata into a genuine East Asian gateway, not just a domestic centre.
The Korean island escape
One unusual route rounds out the board: Jeju (€699 with a bag) — South Korea’s volcanic holiday island, with luggage included. It’s the priciest fare here and a niche one, but a lovely, offbeat destination — beaches, craters and waterfalls — and proof of Kolkata’s surprising East Asian reach for anyone wanting a Korea trip with a tropical twist.
Bag fares: mixed by route
The split is route-dependent. Kuala Lumpur, Tokyo and Jeju include a checked bag. The cheaper and mid-tier fares — Bangkok, Singapore, Abu Dhabi and Seoul — are shown as base prices, often cabin-led on the lowest class. Indian and regional LCCs charge a premium for bags added late, so if you’re carrying more than a backpack, lock in the allowance when you book.
