Seoul to Kolkata (ICN–CCU) — Airlines, Schedules & Connections

South Korean passport holders need a visa to enter India. The eVisa at indianvisaonline.gov.in is the easiest option: a 30-day eTourist visa costs $25, a 1-year multiple-entry costs $40, and a 5-year multiple-entry costs $80. Processing takes 3 to 5 working days. The eVisa allows entry at 28 designated airports including Delhi (DEL), Mumbai (BOM), Bangalore (BLR), and Chennai (MAA). Apply at least 4 days before travel.

Passport must be valid for at least 6 months with two blank pages. Upload a passport scan, a photo (51mm x 51mm, white background), and provide your Indian hotel address. The eVisa approval is emailed as a PDF. Print two copies: one for the airline at check-in and one for immigration. Traditional sticker visas through the Indian Embassy in Seoul cost about the same and take 5 to 7 working days.

KAL and LIMOUSINE services are reliable. Taxis from central Seoul cost ₩65,000–80,000 and take 60–90 minutes. Deluxe (black) taxis are pricier but English-speaking drivers are more common.
