Today, it&#8217;s a high-traffic corridor used by business travellers, students, festival-goers, and families. With roughly 12\u201316 daily non-stop flights operating in 2026, it&#8217;s well-served and competitively priced for most of the year.<\/p>\n<p>But this route has a dramatic seasonal split.

The aerial distance is approximately 1,310 kilometres, and direct flights cover it in <strong>2 hours to 2 hours 15 minutes<\/strong> \u2014 making this one of the faster metro-to-metro connections in the country.<\/p>\n<p>Kolkata operates a single integrated terminal for both domestic and international flights. It&#8217;s located at Dum Dum, about 17 km from the city centre. The Delhi Airport Metro Express connects New Delhi station to DEL in around 20 minutes, making city-to-airport transit straightforward from both ends.<\/p>\n<p>The Rajdhani Express is the most popular train alternative, but it takes 17\u201320 hours \u2014 roughly 9 times longer than the flight. For most travellers, the air route is the obvious choice on time grounds alone.<\/p>\n<h2>Which Airlines Fly from Delhi to Kolkata in 2026?<\/h2>\n<p>Four major carriers compete on the DEL\u2013CCU route in 2026, giving travellers solid choice across price points and schedules. According to DGCA domestic traffic data, the Delhi\u2013Kolkata route handles upwards of 5,000 passengers daily during peak season, making it one of the busiest east\u2013west corridors in the country.
