Route Cost Calculator
Estimate the cost of one flight between two airports. Public data fills in the airspace crossed, EUROCONTROL en-route charges, fuel burn and carbon costs. Enter your own figures for airport charges, crew, maintenance and ownership to complete the trip cost.
07Airspace crossed & en-route charges
Great-circle route split by flight information region. EUROCONTROL charge = unit rate × (km ÷ 100) × √(MTOW ÷ 50), with 20 km deducted for each take-off and landing in a zone.
| Airspace | km | Unit rate | Charge |

How to estimate the cost of a flight
An airline’s cost for a single flight comes from a handful of blocks. Some are set by regulators and published, so they can be calculated exactly from the aircraft and the route. Others depend on contracts and stay with the operator. The Route Cost Calculator fills in every published block automatically and shows which ones still need your figures.
Air navigation charges
EUROCONTROL en-route charges for each country overflown, terminal charges at the departure airport, and North Atlantic or US overflight fees where the route crosses them.
Fuel and carbon
Trip and taxi fuel by aircraft type and distance, priced at the IATA jet fuel average, plus EU, UK or Swiss ETS allowances and the sustainable aviation fuel mandate.
Airports and taxes
Published landing, passenger, security and parking charges at both airports, and statutory ticket taxes such as UK Air Passenger Duty or the German aviation tax.
Frequently asked questions
What does the Route Cost Calculator include?
It estimates the cost of one flight between two airports: fuel, EU, UK or Swiss ETS carbon or CORSIA, the SAF premium, EUROCONTROL en-route and terminal navigation charges, North Atlantic oceanic and US overflight fees, airport charges at both ends, and statutory ticket taxes. Crew, maintenance, ownership, handling and catering are left for you to enter, because they depend on your airline.
How are EUROCONTROL en-route charges calculated?
Each state’s charge is its unit rate multiplied by the distance factor (great-circle kilometres flown in its charging zone divided by 100, less 20 km for each take-off or landing in that zone) and the weight factor (the square root of MTOW in tonnes divided by 50). The calculator splits the route by flight information region and applies the October 2026 unit rates for all 41 charging zones.
What is the terminal navigation charge?
It pays for approach and aerodrome air traffic services and is charged per departure as the zone’s terminal unit rate multiplied by (MTOW divided by 50) to the power of 0.7. The calculator uses EUROCONTROL’s 2026 terminal unit rates for the 189 airports in the 26 terminal charging zones.
Where do the airport charges come from?
Both airports are priced with the published tariffs in our Airport Cost Calculator: landing, passenger, security, PRM and parking charges for the selected aircraft and passenger load. New airports added there appear in the Route Cost Calculator automatically.
Which ticket taxes are included?
Economy-cabin rates for departures from the UK (Air Passenger Duty from 1 April 2026), Germany (aviation tax from 1 July 2026), France (TTAP solidarity tariff), the Netherlands, Denmark and Portugal. Taxes are shown separately because they are normally passed on to passengers.
How accurate is the estimate?
It is a planning estimate. Charges follow the great-circle route rather than the filed flight plan, fuel burn comes from an open aircraft performance model, and negotiated discounts or incentives are not included. Every assumption can be overridden with your own figure.

Methodology, assumptions & sources
How each cost is calculated
- Distance. Great-circle distance between airport coordinates. Fuel and block time use the flown distance (great circle plus the route extension). Charges and ASKs use the great circle, as EUROCONTROL bills the great-circle distance between the entry and exit points of each zone.
- En-route charges. Global unit rates published by the EUROCONTROL Central Route Charges Office for October 2026 (national rate plus the EUR 0.10 administrative rate), already converted to euro. Distance and weight factors are rounded to two decimals, as on CRCO invoices. The calculator splits the great circle, not the filed route, so the result is an approximation of the bill.
- Airspace boundaries. FIR polygons from the VATSpy data project (simplified). They follow real-world FIRs closely but are maintained for flight simulation; boundaries can differ from the AIP in places.
- Fuel. A climb, cruise and descent profile integrated with OpenAP fuel-flow models (ICAO engine emissions databank and drag polars), with take-off mass built from operating empty weight, an 85% passenger load at 100 kg each, trip fuel and reserves. Taxi fuel uses the engines’ ICAO idle fuel flow. A319neo, A320neo and A321neo use the matching ceo table less 15%, because OpenAP’s neo models give implausibly low burn. Long-haul twins in particular can read high against airline averages; use the adjustment or override fields to calibrate.
- Fuel price. Jet fuel converted at 127.2 kg per barrel (0.8 kg/litre). The IATA figure is a spot-market average; add the into-plane premium for a delivered price.
- Carbon. 3.16 t CO₂ per tonne of fossil jet fuel. EU ETS covers flights departing the EEA to the EEA, Switzerland or the UK; Swiss ETS covers departures from Switzerland to Switzerland or the EEA; UK ETS covers departures from the UK to the UK, the EEA or Gibraltar. Aviation’s free allocation ends in 2026, so 100% is the default share paid. Outermost-region exemptions and SAF allowances are not modelled. Other international flights use the CORSIA price you enter.
- SAF. ReFuelEU Aviation requires at least 2% SAF at EU airports from 2025; the UK mandate is set to 3.6% for 2026 on its 2% (2025) to 10% (2030) path. The calculator charges the premium on that share of trip fuel, and removes the SAF share from the carbon bill.
- Terminal navigation. EUROCONTROL 2026 terminal unit rates for the 26 terminal charging zones (189 airports) under the EU performance and charging scheme, charged per departure as unit rate × (MTOW ÷ 50)0.7 and converted to euro at ECB rates. Airports outside those zones are listed as not included.
- Oceanic and US charges. NATS Shanwick oceanic charge (£57.60 per flight) plus the Atlantic ADS-B data charge (£38.89), from the 2025 UK charges specification, the latest found. FAA overflight fees of $61.75 per 100 nm en route and $26.51 oceanic (14 CFR 187.53) for flights that neither depart from nor land in the US. Other non-EUROCONTROL airspace is listed for you to complete.
- Ticket taxes. Economy-cabin statutory rates for departures from the UK (Air Passenger Duty from 1 April 2026, bands measured from London), Germany (aviation tax from 1 July 2026, distance class approximated by route length), France (TTAP solidarity tariff), the Netherlands (2026), Denmark (2026) and Portugal; none in Spain and Greece. Transfer-passenger exemptions and premium-cabin rates are not modelled. Taxes are shown separately and excluded from the trip cost.
- Carbon and SAF prices. UK and Swiss ETS defaults are the 2025 average auction prices reported by ICAP. The SAF premium is EASA’s 2025 ReFuelEU reference price for aviation biofuels (€1,925/t) minus conventional jet fuel (€640/t).
- Airport charges. Calculated with the Airport Cost Calculator’s own tariff engine and data, loaded from that page: the departure at the origin (origin passengers at the load factor) and the arrival at the destination. Amounts in other currencies are converted at ECB reference rates. Required airport quotes the tariff does not publish are listed as not included. Certified NOx, wingspan and length come from OpenAP estimates where a tariff needs them.
- Block time. Modelled airborne time at the flown distance plus taxi-out and taxi-in. Per-block-hour rates multiply this time.
Formula
Trip cost = fuel + carbon + SAF premium + en-route + terminal + other ANS + airport charges + handling + (catering + distribution) × passengers + (crew + maintenance + ownership + overhead) × block hours
