✈ Route Capacity
1 flights operate this route daily — limited supply on KTM→CCU. Top carrier is BHA with roughly 100% of scheduled daily capacity.
📅 Monthly Delay Risk
How on-time performance typically varies through the year on KTM→CCU based on historical weather and operational patterns:
December-January is peak fog season in North India. Dense morning fog (especially 3 AM-10 AM) regularly drops visibility below the 550m minimum needed for takeoff. Delhi airport — the worst affected — sees hundreds of cancellations and 2-4 hour delays during severe fog spells. Lucknow, Patna, Varanasi, Amritsar, and Kolkata are similarly impacted. Airlines use CAT-III equipped aircraft to operate during lower visibility, but delays remain common.
💡 Tip: Consider booking afternoon or evening flights (post 11 AM) in Dec-Jan — visibility typically improves by mid-morning. Keep buffer time for connections. Check flight status 2-3 hours before departure.
February sees fog frequency reduce significantly but early-morning departures can still face delays of 30-90 minutes on fog-prone days. Severity is much lower than Dec-Jan.
💡 Tip: Fog delays are typically shorter in February. Early-morning flights occasionally delayed; mid-day onwards reliable.
June to September is peak monsoon for most of India's west coast, south, and east. Mumbai, Goa, Kerala, and Karnataka airports see heavy rainfall-triggered delays and occasional diversions. Kolkata is hit by cyclonic systems from the Bay of Bengal. Flight cancellations spike when runways flood or cross-wind limits are exceeded. July is typically the worst month.
💡 Tip: Book refundable fares during monsoon months. Avoid tight connections — monsoon delays can cascade. Late morning flights (8-11 AM) tend to be less affected than afternoon thunderstorm window.
April-May brings sudden thunderstorms ("Kalbaisakhi") to East and North India, typically in afternoon and evening hours. Flights in 3 PM-8 PM window most affected. Delays of 45-120 minutes common on stormy days at Kolkata, Bhubaneswar, Patna.
💡 Tip: Book morning flights (before 2 PM) during April-May if flying to/from East India. Check weather forecast the day before.
Oct-Nov is cyclone season for the Bay of Bengal. Chennai, Kolkata, Bhubaneswar, Vizag can see days-long shutdowns during major cyclones. Non-cyclone days are usually fine. Risk is episodic, not constant.
💡 Tip: Monitor weather advisories when booking Oct-Nov travel to East Coast. Most days are normal — only named cyclones trigger major disruptions.

Group booking & family travel on Kathmandu to Kolkata
Travelling as a family or group of 5+ passengers on Kathmandu-Kolkata unlocks different fare structures, baggage allowances, and seating considerations than solo or 2-passenger travel. Below is what experienced family travellers tend to optimise for on this route.
Group fares (5+ passengers)
- Airline group desks: for 9+ passengers booked together, most Indian airlines (IndiGo, Air India, SpiceJet, Akasa) have dedicated group-booking desks that often quote 3-8% below the published online fare. Email groups@goindigo.in, groups@airindia.com, etc. with travel dates, sector, passenger count.
- HappyFares group-booking service: for Kathmandu-Kolkata bookings of 6+ passengers, contact us via WhatsApp 7670070070 for negotiated group rates that include the ₹0 convenience fee benefit on each ticket.
- Don't split the booking: booking 8 passengers as one PNR locks the same fare for everyone. Booking as 4+4 PNRs risks one half repricing if fare buckets shift between submissions.
Family travel tips (with children / infants)
- Infants (under 2): all Indian carriers charge ₹0 base fare for lap infants on domestic Kathmandu-Kolkata; 10% of adult fare on international. Bassinet seating must be requested at the time of booking (limited to row 1 of each cabin).
- Children 2-12: typically full adult fare on most Indian carriers (no child discount domestic). Some international carriers (Singapore Airlines, Emirates) offer 25% off for accompanied children.
- Seat selection: when booking, pay ₹100-500/seat to lock adjacent seats — otherwise the airline algorithm may scatter your family across the cabin. IndiGo UpFront and SpiceMax include free seat selection.
- Baggage: domestic Kathmandu-Kolkata allows 15 kg checked per adult + 7 kg cabin. Children get full adult allowance; lap infants get 10 kg checked + 1 collapsible stroller free.
- Special meals: request child meal (CHML) or vegetarian (VGML) at booking; meal preferences cannot be changed at the airport.
HappyFares Easy Refund for families
- 24-Hour RefundGuard (₹199/pax): for families locking in plans 60+ days out, this lets you cancel within 24 hours of booking for a full refund if plans shift. Cost for family of 4 = ₹796 — covers ~₹15,000+ in potential cancellation fees.
- Smart Saver Cancel-for-Any-Reason (₹399/pax): on eligible fare classes, lets you cancel up to 24 hours before departure for a full refund. Family of 4 = ₹1,596 — peace of mind for an Kathmandu-Kolkata trip booked 3-6 months ahead.
