Looking for cheap flights from Delhi to Sylhet? FlightGPT compares live DEL to ZYL fares across every connected source — Indian carriers, Gulf hubs, OTAs and trusted travel agents — and shows the cheapest options side by side. Whether you want a Delhi to Sylhet non-stop tomorrow, a last-minute weekend deal or the lowest price three months out, every active Delhi-Sylhet fare is one search away.
There's no widebody or regional non-stop from North India to Sylhet, so plan to connect. The fastest single-ticket route is Delhi to Dhaka (about 2h 30m on IndiGo or Biman) and then the 40–50 minute domestic feeder to ZYL. Alternatively, fly Delhi to Kolkata (around 2h 10m) and take the short cross-border hop, with Kolkata sitting only ~350 km from Sylhet. Self-connecting in Kolkata is cheaper but needs a 3–4 hour buffer for double immigration and bag re-check.
From Delhi, Dhaka is the more convenient single-PNR hub: Biman and US-Bangla offer same-day ZYL connections and through-bag handling. Kolkata wins on price and proximity, with high non-stop frequency from Delhi feeding short onward flights. If you book two separate tickets to save money, pair this with our Delhi to Kolkata guide to time the first leg so you reach CCU with margin for the international onward flight.
Combining a domestic Indian leg with a short international one, total economy round-trips typically land between ₹20,000 and ₹36,000, depending heavily on season. The cheapest fares show up February through April and in the August–September monsoon lull. Eid weeks and the November–January peak can push one-ways past ₹23,000. Booking five to seven weeks ahead and flexing your dates by a day usually unlocks the better-priced connections.
Bangladesh issues no visa on arrival to Indians, so you must obtain a sticker visa in advance via the Bangladesh High Commission's IVAC centres. Processing generally runs 5–10 working days, so apply at least two weeks out with return tickets and hotel proof in hand. Our visa guide walks through the paperwork; make sure your endorsement covers an air arrival at Osmani (ZYL) rather than only a land port.
Osmani International is roughly 10–12 km from downtown Sylhet, a single-terminal facility where formalities are quick outside the Eid surge. Pre-paid taxis and CNG autos reach the city in 20–30 minutes for a few hundred taka, and the Srimangal tea estates lie a further 2–3 hours by road. Withdraw some taka before leaving the terminal and arrange a hotel pickup if your connecting flight lands after dark.
The November-to-February dry season is the sweet spot for Sylhet, with mild 18–28°C days perfect for the haors, the Ratargul swamp forest and tea-garden walks. The June–September monsoon delivers heavy rain and seasonal flooding that can disrupt the short ZYL feeders. Because Sylhet is only 30 minutes ahead of IST, you won't feel jet lag, so a midday Delhi departure can land you in tea country by evening.
Route through Dhaka on one PNR if you want airline re-protection when a leg runs late. For a self-connect in Kolkata, take an early Delhi flight to leave a fallback option, and stick to the 7 kg domestic cabin allowance. India–Bangladesh combined fares often cap free checked baggage at 20–30 kg, so confirm the lowest common allowance. International check-in at ZYL closes about 60 minutes before departure, so don't cut the return tight.
No. DEL–ZYL has no direct service; you connect once via Dhaka or Kolkata for a total journey of about 5–7 hours.

Just 30 minutes — Sylhet is UTC+6 versus India's UTC+5:30, so there's effectively no jet lag.
