Dehradun to Kolkata is not flown non-stop, so you change planes — Delhi (DEL) is the standard connecting point. IndiGo carries the most passengers on both legs and lets you buy DED'Delhi'Kolkata on a single ticket; Air India is the main full-service alternative. The DED→DEL leg runs ≈ 55m and DEL→CCU ≈ 2h 5m, so your total journey is driven mainly by the layover you pick.
The cheapest months to fly into Kolkata are usually the summer of April–June, before the eastern monsoon, and again in late January–February. Prices peak sharply around Durga Puja (September–October), the city's biggest festival, and over Christmas–New Year. For a connecting domestic fare, book ≈ 3–6 weeks out; FlightGPT shows when the combined DED–CCU price is lowest.
Allow ≈ 4.5–6.5h end to end via Delhi, with about 3h of actual flying and the balance as layover.

Keep a comfortable buffer at Delhi — at least 75–90 minutes — especially if your two flights depart from different terminals.
Standard domestic checked baggage is typically 15 kg on saver fares and 20–25 kg on full-service or bundled tickets, with 7 kg cabin.

Arrival is at Netaji Subhas Chandra Bose International (CCU), ≈ 17 km from central Kolkata, with prepaid taxis and app cabs at the kerb.
