The statistics on commercial aviation covers scheduled and non-scheduled air traffic. One Community airport, Luxembourg (ELLX category 3), supplies all data.   Based on European legal bases results are transmitted to the statistical office of the European Union (Eurostat) three months after the reference quarter in the form of aggregated monthly data.

The survey includes all flights with passenger, freight and mail as well as empty leg flights in domestic and international traffic. EETN receives electronic messages from the handling companies or airlines (in order to perform the necessary operations and billing/invoice procedures) but in some occasions (if electronic data is not available) data is also collected from the airlines/handling agents by other means. All data are monthly transmitted by airport on flight level to Statec by e-mail or by using electronic data transmission tool. In addition to aircraft data (registration, seats, payload etc.), information on the passengers, freight and mail volumes (number, quantity and destination etc.) are collected.
The statistics are compiled and transmitted to Eurostat by Statec on monthly basis.

Three data sets required by the Regulation – A1, B1 and C1 – are provided to Eurostat:

• Dataset A1 - Flight Stage dataset : periodic flight stage data registered for airport-to-airport routes, and broken down by arrivals/departures, scheduled/non-scheduled, passenger service/all-freight and mail service, airline information and aircraft type. The values provided concern passengers on board, freight and mail on board, commercial air flights as well as passenger seats available.
• Dataset B1 - On Flight Origin/Destination dataset : periodic on flight origin/destination data registered for airport-to-airport routes, and broken down by arrivals/departures, scheduled/non scheduled, passenger service/all-freight and mail service and airline information. The values provided concern passengers carried and freight and mail loaded or unloaded.
• Dataset C1 - Airport dataset: periodic airport data registered for declaring airports, and broken down by airline information. The values provided concern total passengers carried, total direct transit passengers, total transfer (indirect transit) passengers (optional variable), total freight and mail loaded or unloaded, total commercial aircraft movements and total aircraft movements.

Data sets A1, B1 and C1 are provided on monthly basis.
Airports handling less than 15 000 passenger units annually are not included in the data sets.
Freigh and mail figures are provided in tonnes with three decimal places.
Number of passengers does not inlcude infants in arms.

Airports are classified according to ICAO (International Civil Aviation Organization) airport coded as listed in ICAO document 7910.

Aircrafts are classified according to aggregated aircraft categories based on the ICAO aircraft codes as listed in ICAO document 8643.

Airlines are classified according to the ICAO airline codes as listed in the ICAO document 8585. When providing the data to Eurostat, the region where they are licensed is coded accordingly either as European Union (EU) or outside the European Union (non-EU).

Commercial air transport.

The main concepts used in this domain are the following:

Community airport - a defined area on land or water in a Member State subject to the provisions of the treaty, which is intended to be used either wholly or in part for the arrival, departure and surface movement of aircraft and open for commercial air services.

Flight stage - the operation of an aircraft from take-off to its next landing. This is linked to the definition of passengers (or freight and mail) on board.

Passengers on board - all passengers on board of the aircraft upon landing at the reporting airport or at taking off from the reporting airport. All revenue and non-revenue passengers on board an aircraft during a flight stage. Includes direct transit passengers (counted at arrivals and departures).

Direct transit passengers - passengers who, after a short stop, continue their journey on the same aircraft on a flight having the same flight number as the flight on which they arrive.

Transfer of indirect transit passengers - passengers arriving and departing on a different aircraft within 24 hours, or on the same aircraft bearing different flight numbers. They are counted twice: once upon arrival and once on departure.

Freight and mail on board - all freight and mail on board of the aircraft upon landing at the reporting airport or at taking off from the reporting airport. All freight and mail on board an aircraft during a flight stage. Includes direct transit freight and mail (counted at arrivals and departures). Includes express services and diplomatic bags. Excludes passenger baggage.

On flight origin and destination - traffic on a commercial air service identified by a unique flight number subdivided by airport pairs in accordance with point of embarkation and point of disembarkation on that flight. For passengers, freight or mail where the airport of embarkation is not known, the aircraft origin should be deemed to be the point of embarkation; similarly, if the airport of disembarkation is not known, the aircraft destination should be deemed to be the point of disembarkation. This is linked to the definition of passengers carried and freight and mail loaded or unloaded.

Passengers carried - all passengers on a specific flight (with one flight number) counted once only and not repeatedly on each individual stage of that flight. All revenue and non-revenue passengers whose journey begin or terminates at the reporting airport and transfer passengers joining or leaving the flight at the reporting airport. Excludes direct transit passengers.

Freight and mail loaded or unloaded - all freight and mail loaded onto or unloaded from an aircraft. Includes express services and diplomatic bags. Excludes passenger baggage. Excludes direct transit freight and mail.

Passenger unit - one passenger unit is equivalent to either one passenger or 100 kilograms of freight and mail.

The data are collected at individual airport level.

Four categories of Community airports are defined by the Regulation (EC) N°1358/2003:

• Category "0": Airports with less than 15 000 passenger units per year are considered as having only "occasional commercial traffic" without obligation to report.
• Category "1": Airports with between 15 000 and 150 000 passenger units per year shall transmit only aggregated airport data (Data set C).
• Category "2": Airports with more than 150 000 passenger units and less than 1 500 000 passenger units per year shall transmit flight stage data, on flight origin destination data as well as aggregated airport data (Data sets A, B and C).
• Category "3": Airports with at least 1 500 000 passenger units per year shall transmit flight stage data, on flight origin destination data as well as aggregated airport data (Data sets A, B and C).

Airports under category ‘0’ are not included in the statistics provided to Eurostat.

Commercial airports located on the territory of Luxembourg with more tahn 15000 passenger units per year.

Monthly data has been reported starting from 2005 for flight stage and on flight origin destination data (passengers and freight and mail data); Some historical annual data are available - passengers on board as from 1993 and freight and mail on board as from 1994; annual data on freight and mail loaded and unloaded, passenger carried and direct transit passengers are available as from 2000. Monthly transfer passenger data available as from August 2013.

Not applicable.

The units used depend on the variables collected within each data set and are: number of passengers, tonnes, flights, aircraft movements and passenger seats available.

The weight of freight and mail is transmitted in tonnes with three decimal places.

Reference period is the calendar year 2022.

European level: until 2002, the data were provided to Eurostat on a voluntary basis; since 2002 data provision is based on an EP and Council framework legal act and on several implementing Commission Regulations:

• Regulation (EC) No 437/2003 of the European Parliament and of the Council of 27 February 2003 on statistical returns in respect of the carriage of passengers, freight and mail by air.
