About Flight Cost Estimator

Flight prices depend on route, season, booking timing, airline type, and cabin class. Booking 6-8 weeks ahead typically gives best prices for domestic flights; 3-6 months ahead for international. Tuesday and Wednesday departures are often 10-20% cheaper than weekends. The Google Flights price calendar helps find the cheapest date combinations quickly.

Hidden costs that inflate cheap fares include baggage fees Rs 500-3,000 per bag each way, seat selection fees, meal fees, and booking convenience fees. Budget airlines often end up costing as much as full-service carriers once all extras are added. When estimating road trip costs, calculate: total distance divided by fuel efficiency, times current fuel price, plus tolls and parking charges.

Frequently Asked Questions

This tool labels your fare Excellent, Good, Average or Expensive based on simple, illustrative thresholds on the price-per-km figure. It's a quick relative comparison between your own fares and routes, not an industry-audited benchmark, since real value also depends on route, season and cabin class.
It multiplies your flight distance in kilometres by an average emissions factor of roughly 0.255 kg CO2 per km, then adjusts by your cabin class multiplier — premium cabins have a bigger footprint per passenger because they take up more space on the aircraft.
Cost per mile/km normalises for distance, which is useful when comparing tickets on routes of different lengths. Cost per hour normalises for flight duration, which is more useful when comparing a direct flight against a longer connecting itinerary at a similar price.
Baggage fees, seat selection, in-flight meals and booking convenience fees are common extras on top of the base fare. Budget airlines in particular can end up costing as much as full-service carriers once these are added, so factor them in separately when comparing total trip cost.
