Delays decreased in August 2012, with airline delay data for all causes showing an average delay per delayed flight of 25 minutes, this was a decrease of 9.8% in comparison to the delays observed in August 2011. This was the best August punctuality of recent years. Digest – Delays to Air Transport in Europe August 2012 FOREWORD This report gives an overview of the delay situation in the European Civil Aviation Conference Area. This report has been prepared by the Central Office for Delay Analysis (CODA), a service of EUROCONTROL. It is based on the EUROCONTROL CODA database which contains delay data provided directly by airlines. The report consists of an overview of the reporting period, a summary of the main delay effects, and a series of charts and graphics, which illustrate the main characteristics of the reporting period. A glossary of terms and abbreviations used throughout the report is given in Annex 1. Airline data from the CODA database contains real recorded delays provided to CODA by airlines and is based on the difference between scheduled time of departure and actual off block time. This report discusses delays from all-causes; for information regarding ATFCM delays see the complementary reports available at http://www.eurocontrol.int/articles/network-operations-monitoring-and-reporting Table of Contents 1.

Headlines and Overview. August 2012 saw a reduction in all causes of delay when compared to August 2011. Airport delays saw small increases following delays in Brussels as a result of works in progress, an airline strike on the 31st August affected Frankfurt with the airport seeing delays to parking stand unavailability. Amsterdam Schiphol experienced delays due to a historical bomb disposal on the 29th. Weather conditions, particularly low visibility, thunderstorms and winds impacted operations at Brussels, Frankfurt, London Heathrow and Palma airports. The average delay per delayed flight (ADD) for departure traffic as well as for arrival traffic decreased respectively by 2.8 and 2.5 minutes The percentage of flights delayed (by 5 minutes or more) decreased by 3.8 percentage points for departures and 4.4 percentage points for arrivals. Figure 1. Average Delay per Delayed Departure and Percentage of Delayed Departures Comparison Figure 2. Average Delay per Delayed Arrival and Percentage of Delayed Arrivals Comparison EUROCONTROL 3 CODA Digest – Delays to Air Transport in Europe August 2012 Analysis of the delay causes contributing to the August 2012 average delay per flight of 8.5 minutes (Figure 3) shows a decrease in the contribution of reactionary delay, this was down from 4.6 to 3.58 minutes per flight. ATFM en-route related delays decreased to 0.45 minutes per flight from 0.96 minutes per flight in August 2011. Note: IATA Delay Code 19 (Passengers with Reduced Mobility) is included in airline grouping Figure 3. Primary delay causes, August 2011 vs. August 2012 Figure 4. Primary delay causes, August 2012 EUROCONTROL 4 CODA Digest – Delays to Air Transport in Europe August 2012 Figure 5. ATFM Share of All-Causes Primary Delay. Looking further into the history of the ATFM proportion of primary delay (Figure 5), the en-route percentage share of the total primary delay minutes was 9.7%, this was the lowest share noted since August 2008. The share of ATFM airport delay increased by 2 percentage points, however ATFCM Airport delay minutes fell by 2% (Figure 4). EUROCONTROL 5 CODA Digest – Delays to Air Transport in Europe August 2012 2. All-Causes Departure Delay Summary 1 The average delay per flight from all causes of delay decreased compared to August 2011 by 24% to 8.5 minutes per flight (Figure 6). In August 2012, 45% of flights departed within the 5 minute threshold before or after the scheduled departure time. Flights departing >5 minutes ahead of schedule increased by 2 points to 17% (Figure 7) Figure 6. Average delay per flight (All-Causes) for Departures Figure 7. All-Causes Departure Punctuality 2011 vs. 2012 1A flight is considered delayed as from 5 minutes. The analysis was based on airline data provided to CODA. Unless otherwise mentioned, a flight is considered delayed/advanced as from 5 minutes. EUROCONTROL 6 CODA Digest – Delays to Air Transport in Europe August 2012 Figure 8. Long departure delays >120 minutes Figure 9. Primary and reactionary all-cause delay, by IATA code (%) Figure 9 shows that: Reactionary delay and Technical and Aircraft Equipment saw a decrease in its contribution to the average delay per flight in minutes but their share of delay remained at the similar level as previous year. The ATFM En-Route Demand/Capacity delay in minutes as well as it share dropped compared to August 2011 (0.42 minutes and 3%).
