Updates on aviation in the Channel Islands
The latest airline data for both Aurigny and Blue Islands, covering:
👥 Passengers Uplifted – calculated by counting each revenue passenger on a particular flight (with one flight number) once only and not repeatedly on each individual stage of that flight
🛫 Stage Flights Operated – counted from when an aircraft takes off to when it next lands (including technical stops)
💺 Average Load Factor – calculated by dividing seat-kilometres used by seat-kilometres available and expressing it as a percentage
📦 Tonnes of Cargo Carried – calculated by counting each tonne of revenue freight or mail on a particular journey (with one flight number) once only and not repeatedly on each individual stage of that flight, 1 Tonne = 1000kg
🗺 Distance Flown – calculated by multiplying the number of flights performed by the stage distance
⏰️ Aircraft Hours – measured on the basis of block-to-block times ie measured from the time the aircraft moves from the loading point until it stops at the unloading point
📊 Average Daily Utilisation per Aircraft – the total number of aircraft hours flown (passenger and cargo) divided by the number of aircraft days available for the period in question
📈 Performance Index – calculated by the average of all percentages for the 6 categories measured (cargo uplifted is not included in this calculation due to its highly changeable nature and small differences so tends to skew percentages) that month. It does not represent any specific metric, nor have any technical basis but is a way to compare to the previous year’s performance and the current year’s performance. In general, stable indexes around 0 indicate similar performance to the prior period with positive and negative numbers indicating improvements and decreases in performance respectively
All data is sourced from the CAA’s UK airline data page. It uses the data from the all services section (including non-scheduled and charter). Comparisons are to the same period the year prior, and are the percentage change to the prior year rounded to 1dp. The percentage for average load factor is the difference compared to the year before (ie 63.0% in 2025 – 58.2% in 2024 = -4.8% given in percentage points) and is not given as a percentage change.
