Looking for cheap flights from Kolkata to Surat?

Whether you want a Kolkata to Surat non-stop tomorrow, a last-minute weekend deal or the lowest price three months out, every active Kolkata-Surat fare is one search away.
The Mumbai routing (CCU–BOM + BOM–STV) is generally the most convenient: BOM–STV is a short ≈ 1h hop operated daily by IndiGo and SpiceJet, and Mumbai offers a much larger transit lounge with food, SIM shops, and forex. The CCU–BOM sector is ≈ 2h 20m. The Ahmedabad alternative (CCU–AMD + AMD–STV) saves ≈ 15–20 minutes in the air but AMD–STV frequencies are fewer — typically 1–2 daily — so layover windows can be longer or shorter with less flexibility to rebook if missed. For business travellers, Mumbai gives more rebooking options; for leisure travellers who want the cheapest combined fare, compare both hub options on the same date.
Surat's calendar is dominated by the diamond and textile trade, and flight demand spikes around key industry events. The International Gem and Jewellery Show (IGJS), textile exhibitions, and Gujarat-wide Diwali shopping season push fares on this corridor to ₹10,000–₹16,000 one-way. During lean business periods (June–August) and non-festival months, combined CCU–STV fares start at ≈ ₹5,000–₹7,500 when booked 4–6 weeks ahead as of June 2026. Kolkata's Durga Puja (October) also sees heavy outbound demand from Bengali traders returning to their Gujarat businesses — book 8–10 weeks ahead for that window.
The CCU–BOM leg on IndiGo or Air India runs ≈ 2h 20m and is typically operated by an A320neo. BOM–STV takes ≈ 1h on an A320 or ATR 72. At Mumbai, domestic connections involve clearing the BOM domestic-domestic transit zone (no baggage recheck if on a single PNR). BOM T1 is IndiGo's base and is efficiently laid out; food options are plentiful. Note that BOM has two domestic terminals — T1 (LCC) and T2 (AI and international); ensure both legs depart from the same terminal or factor in a shuttle between terminals when planning layover time (15–25 minutes minimum). IndiGo's two legs typically both use T1.
IndiGo's base fare includes 7 kg cabin baggage per segment. For a two-segment journey, this means 7 kg cabin only unless you add hold luggage — essential for business travellers carrying samples, swatches, or diamond-trade parcels. Add 15 kg at booking for ≈ ₹700–₹1,000 per segment (as of June 2026); a combined two-segment add-on runs ≈ ₹1,500–₹2,000. Air India includes 15–25 kg on most economy fares. Diamond traders should note that loose stones and high-value goods should be declared at check-in and carried as cabin items; airline liability on lost checked valuables is capped under the Carriage by Air Act.
Surat Airport (STV) is located ≈ 12 km south of the city centre. The terminal is a mid-sized single building that underwent expansion in 2022; it handles ≈ 1,000–1,500 passengers daily. Pre-paid taxis to the city centre cost ≈ ₹300–₹450; Ola and Uber are active at the airport exit. The airport is close to the main diamond-bourse cluster in Varachha and Mahidharpura, making it particularly convenient for trade visitors. For the Diamond Research and Mercantile City (DREAM City), allow 25–30 minutes by cab from STV. No metro connectivity yet, but BRTS bus services cover the broader city.
No visa or special permit is required for Indian citizens on this domestic route. A government-issued photo ID — Aadhaar, voter ID, PAN with photo, or valid passport — is all you need at both CCU and STV. DigiYatra facial recognition is active at CCU and is being deployed at STV; enrol via the DigiYatra app to cut boarding queues on your next trip. Gujarat has no Protected Area or Inner Line restrictions; visitors can travel freely throughout the state. For transit at Mumbai, no additional paperwork is needed for domestic-to-domestic connections.
Surat is India's fastest-growing major city and a remarkable story of industrial transformation. The historic Dutch and Portuguese merchant quarters (Surat Fort, Dutch Cemetery, English Factory) hint at the city's past as a Mughal-era trade emporium from which the East India Company first launched. The Dumas Beach, ≈ 21 km from the city, is one of Gujarat's most visited beaches — legendary for paranormal stories that have made it a quirky attraction in its own right. Surti cuisine — the distinctive papdi-no-lot, ponk (tender sorghum seeds), and rich Surti locho — is a regional culinary tradition that draws food tourists. The textile market in Ring Road is one of India's largest fabric wholesale hubs.
No regular non-stop service operates. The standard connection is via Mumbai (BOM) or Ahmedabad (AMD), giving a total travel time of ≈ 4.5–6 hours including layover.
Mumbai (BOM) offers more frequent BOM–STV departures (≈ 3–4 daily) and better rebooking options if your Kolkata leg is delayed. Ahmedabad (AMD) can be cheaper on certain dates but has fewer AMD–STV frequencies.
As of ${FARES_AS_OF}, combined CCU–STV fares start at ≈ ₹5,000–₹7,500 one-way booked 4–6 weeks ahead. Diwali and diamond-trade event windows push fares to ₹10,000–₹16,000.
STV is ≈ 12 km from the city centre and ≈ 15–20 km from the Varachha diamond bourse cluster — about a 25–30 minute drive by cab (≈ ₹350–₹500).
Airlines strongly recommend keeping high-value items in cabin baggage. Liability under the Carriage by Air Act is capped at ≈ ₹1,200 per kg for checked bags, far below typical diamond values. Declare at check-in and carry as hand baggage.
IndiGo usually offers the lowest combined fares on this route. Booking a single IndiGo itinerary (one PNR) for both legs also gives connection protection, making it the preferred choice for most business travellers.
