Airlines on this route
Multiple carriers operate the Kolkata–Guwahati sector. Which airlines fly this route, how frequently they depart, and whether direct flights are available depends on the travel date — the live search above shows real inventory. Connecting itineraries via hub airports like Mumbai, Delhi, Hyderabad, or Bangalore are also available and can be significantly lower than direct fares on certain dates.
When to book for the best fares
Fares on the Kolkata–Guwahati route fluctuate based on demand, season, and how far in advance you book. As a general rule, booking 3–6 weeks before your travel date gives the best balance of availability and price. Mid-week departures (Tuesday and Wednesday) are usually 10–20% lower than Friday evening and Sunday afternoon flights, which are in high demand with working professionals. Early morning (5 am–8 am) and late night (9 pm onwards) flights are typically lower than peak-hour slots.
Flight duration
Non-stop flight duration from Kolkata to Guwahati depends on the specific airports, aircraft type, and air traffic conditions on the day. Most direct domestic sectors in India range from 1 hour to 3 hours in the air. One-stop connecting itineraries add transit time at the hub airport and may take 4–7 hours total but are often available at a lower price.
Zero booking fee — what it means
OnlyOnTrip charges ₹0 convenience fee on every flight booking — domestic or international — regardless of the payment method you use. Most competing platforms charge ₹100–₹450 per passenger as a convenience or service fee on top of the advertised fare. On a family trip with four passengers, this alone saves you ₹400–₹1,800 per booking. You also get free seat selection and free meal selection (where the airline supports it) at checkout, with no upsell screens or hidden extras.
Baggage allowance
On domestic Indian routes, IndiGo, SpiceJet, and Akasa Air include 15 kg check-in baggage and 7 kg cabin baggage as standard on most fare types. Air India typically includes 15–25 kg check-in depending on the ticket class. Excess baggage fees are significant at the airport check-in counter (₹350–₹600 per kg) — if you anticipate needing extra weight, pre-purchase additional baggage on OnlyOnTrip before departure for a much lower per-kg rate. Cabin baggage must fit in the overhead bin (55 cm × 35 cm × 25 cm), and all airlines enforce the 7 kg limit at the gate.
