At about 350 km, Kolkata to Sylhet is a genuine short-haul international hop — the great-circle distance is shorter than Kolkata to Bhubaneswar. When a direct service operates, air time is roughly 50 minutes to an hour. Direct frequencies are thin, however, so many travellers connect through Dhaka (DAC), flying CCU–DAC in about 50 minutes then a 35-minute domestic-style hop to ZYL. Either way, this is the fastest gateway from India into Sylhet's tea country.
Biman Bangladesh and US-Bangla dominate the Kolkata–Bangladesh corridor; IndiGo also serves CCU–DAC. Direct or one-stop economy round-trips typically run ₹14,000–₹26,000 depending on season and demand around festivals. Because the sector is short, base fares are low but taxes and surcharges form a big share of the total. Booking 3–5 weeks ahead and avoiding Eid and Durga Puja peaks can keep you near the bottom of the band.
Despite the short distance, Bangladesh requires Indian passport holders to hold an advance sticker visa — there is no visa-on-arrival at Sylhet or Dhaka. Apply through the Bangladesh Deputy High Commission in Kolkata or an IVAC centre; turnaround is usually 4–8 working days for Kolkata residents. Carry return tickets, hotel proof and bank statements. See the visa guide; with no e-visa option, start the process at least 10 days before you fly.
If a direct CCU–ZYL flight matches your dates, take it — under an hour beats any connection. When direct seats are sold out or off-schedule, the Dhaka routing is reliable: DAC–ZYL runs many times daily on Biman and US-Bangla over just 180 km. Total via-Dhaka travel, including a 1–2 hour layover, lands around 3–4 hours, still far quicker than overland road-and-rail crossings through the Dawki/Tamabil border.
Sylhet shines from November to February, with dry days, highs of 20–27°C and the Srimangal gardens at peak green. The June–September monsoon swells the haor wetlands and can flood the basin, but it drops fares 15–25% and makes for dramatic, misty tea-country photos. October is a calm shoulder month with thinner crowds and moderate prices.
ZYL is compact and recently modernised, geared to heavy UK and Gulf diaspora flights. Arriving from Kolkata, immigration usually takes 20–40 minutes outside the evening diaspora rush. The city centre is about 15 km from the terminal; a prepaid car runs ₹300–₹700 equivalent in taka. Money-changers and SIM kiosks sit near arrivals, so you can get cash and connectivity before stepping out.
On this short international sector, Biman and US-Bangla economy generally allow 20–30 kg checked plus 7 kg cabin — generous for such a brief flight, which is why diaspora travellers favour it for ferrying goods. Excess runs about ₹500–₹700 per kg. If self-connecting via Dhaka on separate tickets, confirm both allowances, and leave at least 90 minutes between the international and domestic-style legs.
When flown direct it is about 50 minutes to an hour over roughly 350 km; via Dhaka, total travel is around 3–4 hours with the layover.
Yes — an advance sticker visa from the Bangladesh Deputy High Commission/IVAC, processed in about 4–8 working days. No visa-on-arrival exists.
