📅 Monthly Delay Risk
How on-time performance typically varies through the year on CCU→KTM based on historical weather and operational patterns:
December-January is peak fog season in North India. Dense morning fog (especially 3 AM-10 AM) can drop visibility below the limits many aircraft and crews may operate in. Delhi airport, among the worst affected, sees long delays and cancellations 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 ("Kalbaishakhi") to East and North India, typically in afternoon and evening hours. Afternoon and evening flights are the most affected, with delays on stormy days at Kolkata, Bhubaneswar and 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.
💡 Typical price range on this route
Prices on CCU→KTM typically range from ₹25,391 to ₹31,670, based on 330 fare observations over the last 30 days.
The current lowest fare we're tracking (₹23,494) is below the typical range, excellent deal.
