February 2012 traffic was below the 4 previous years and alsowell below the forecast.

This graph shows the variation in total traffic for the last 12-month period relative to that for the 12-month period before.Accordingly, the total traffic from Feb11 to Feb12 increasedby 1.9% relative to that from Feb10 to Feb11.


4/14


Several main airports continued to experience a decrease in traffic during February 2012 (e.g. London Heathrow, Paris CDG,Frankfurt, Madrid, Munich, Rome Fumicino and Barcelona). The largest decreases were experienced in Palma de Mallorca,Madrid, Athens, Las Palmas and Prague. Ferihegy Budapest recorded a 29.9% decrease due to Malv Hungarian Airlinesceased operations. The largest increases in traffic were recorded at Bergen Flesland, Istanbul Ataturk and London City.

For air operators, the most significant decreases were recorded by Czech Airlines (-30.5%), Iberia (-26.2%), Royal Air Maroc (-24.1%), Cimber Air A/S (-19.2%) and Air Europa (-16.8%). The largest growth was recorded by United Airlines (140.7%) andNaysa (40.3%). All of these changes were due to airline consolidation and restructuring rather than traffic growth.

Some major carriers (S.A.S, Turkish Airlines and KLM) recorded a growth in traffic in February 2012 which is in line withAmsterdam and Istanbul airport growth.

Unidentified operators (mainly General Aviation) recorded a decrease of 7.1% in February 2012.


5/14


Stavanger, Tallinn and Warsaw ACCs experienced a significant increase in traffic. Spain (Madrid, Seville, Barcelonaand Palma ACCs), Rome and Skopje ACCs recorded significant decreases in traffic. The decrease in Malta is bothdue to slow recovery from the Libyan airspace closure and the general decline in traffic level.

These are the top 20 delay generating locations for the beginning of 2012. Figures are the average daily delays in minutes. Thetop 20 location represents 76.3% of the entire Network ATFM delays, the top 5 locations represents 38.9% of the NetworkATFM delays. Istanbul, Amsterdam, London Heathrow, Munich and Zurich airports registered the most significant delays mainly due to weather

conditions: snow, strong wind and low visibility.

Frankfurt delays were caused by the Apron and marshalling personnel strike during 9 days between the 16th

and 29th

February.

Nicosia, Langen and Warsaw ACCs recorded delays mainly due to ATC capacity and staffing. Marseille and Reims ACCsrecorded delays mainly due to industrial action.

Paris ACC registered delays due to ATC capacity and industrial action.

Malmo recorded en-route delays due to the implementation of the new ATC system COOPANS.

Delays in Ankara ACC were due to reduced ATC Capacity in ORBB (Baghdad) FIR (NOTAM A0004/12).

Since the beginning of the year, an average of 179 flights perday was subject to an en-route delay of more than 15 minuteswhich is below the 2011 result.

In February the monthly optimum* en-route delays (8030 min)was exceeded (8305 min) despite the lower than expectedtraffic. Performance in January has assisted the year-to-dateen-route delay per flight result (0.29 min/flt) staying lower thanthe optimum* year-to-date target (0.34 min/flt).

6. ALL AIR TRANSPORT DELAYS (Source: CODA)

The analysis below is based on the data provided to CODA by the airlines (AO). As the data collection for February12 is not yetcomplete at the time of writing, this analysis covers the latest available 13-month period (Jan2011-Jan2012) and containsdetails on 68% of commercial flights in the ECAC region.

ATFM delays reported by airlines are often lower than the ATFM delays calculated by the network manager (NM). ATFMdelays of NM are the (flight) planned delays whereas the airlines report the actual experienced ATFM delay on departure.

For instance, a flight with an ATFM delay may also have a handling delay absorbed within the ATFM delay. For the airline, apart of this delay is the ATFM delay and the rest is the handling delay

Airline reported en-route ATFM delay in January 2012 (0.17minute per flight) is below the NM reported average en-route ATFM delay of 0.22 minute per flight. As airlines mayassign multiple delay reasons for a delayed flight, some ofthe en-route ATFM delay may be attributed to other reasonsif the other reason prevented the flight from obtaining a slotimprovement. A common example is a NM reported en-route ATFM delay reported by airlines as a split between

reactionary and en-route ATFM delay. According to airlinereports, in January 2012 Primary delays accounted for 55%(4.8 min/flt) of which 2% (0.17 min/flt) is attributed to en-route ATFM delays. The rest are the Reactionary delayscounted for 3.9min/flt.

Based on airline data, the reported share of reactionarydelays in January 2012 remained stable at 45% of delay all-causes.

Both NM and airlines report that en-route ATFM delaysreached the lowest point when observing the last 13months.

The percentage of flights delayed by long ATFM restrictions(exceeding 15' and 30') in January 2012 was the lowestduring the previous 13 months.

The percentage of long departure delays all-causes inJanuary 2012 was lower compared to January 2011 andwas the third lowest during the previous 13 months. Thepercentage of flights delayed by long ATFM restrictions(exceeding 15' and 30') reached its peak during June andJuly 2011, with a similar pattern observed for delays AllCauses. The correlation between long ATFM delays andlong delays All Causes becomes less obvious during

winter months with increased weather related delays.

In February 2012, the percentage of early departures hasincreased well above the yearly average.

Although the overall percentage of traffic departing withintheir slot tolerance window is above the target (at least 80%)there are some airports for which compliance can beimproved.

NM continues to validate the data used and identify issuescontributing to non-compliance.

The chart below shows the top 40 airports (more than 300 regulated flights) with their average daily number and proportion ofregulated flights that departed outside of the Slot Tolerance Window
