Answer the following question: Information:  - East Attica is one of the regional units of Greece. It is part of the region of Attica. The capital of the regional unit is the town of Pallini. The regional unit covers the eastern part of the agglomeration of Athens, and also the rural area to its east.  - Aegean Airlines S.A. ("Aeroporía Aigíou Anónime Etairía" ) is the largest Greek airline by total number of passengers carried, by number of destinations served and by fleet size. A Star Alliance member since June 2010, it operates scheduled and charter services from Athens and Thessaloniki to other major Greek destinations as well as to a number of European and Middle Eastern destinations. Its main hubs are Athens International Airport in Athens, Thessaloniki International Airport in Thessaloniki and Larnaca International Airport in Cyprus. It also uses other Greek airports as bases, some of which are seasonal. It has its head office in Kifisia, a suburb of Athens. Although the airline is the largest airline in Greece, it is not a flag carrier.  - Kropia is a municipality in East Attica, Greece. It is located 16 km southeast of Athens at the fringes of the Athens metropolitan area, and has a land area of 102.0 km. Its population was 30,307 at the 2011 census. The seat of the municipality is in the town of Koropi (pop. 19,164). In descending order of population, its other villages are Kítsi (pop. 4,788), Agía Marína (3,765), Karellás (1,579), and Ágios Dimítrios (1,011).  - An airline is a company that provides air transport services for traveling passengers and freight. Airlines utilize aircraft to supply these services and may form partnerships or alliances with other airlines for codeshare agreements. Generally, airline companies are recognized with an air operating certificate or license issued by a governmental aviation body.  - A passenger (also abbreviated as pax) is a person who travels in a vehicle but bears little or no responsibility for the tasks required for that vehicle to arrive at its destination or otherwise operate the vehicle.  - A codeshare agreement, sometimes simply codeshare, is an aviation business arrangement where two or more airlines share the same flight. Sharing, in this sense, means that each airline publishes and markets the flight under its own airline designator and flight number as part of its published timetable or schedule. A seat can be purchased on each airline's designator and flight number, but is operated by only one of these cooperating airlines, commonly called the operating carrier or more precisely (and in line with definitions in IATA Standard Schedules Information Manual): "Administrating carrier". The term "code" refers to the identifier used in flight schedule, generally the two-character IATA airline designator code and flight number. Thus, XX123 (flight number 123 operated by the airline XX), might also be sold by airline YY as YY456 and by ZZ as ZZ9876. Airlines YY and ZZ are in this case called "Marketing airlines" (sometimes abbreviated MKT CXR for "marketing carrier"). Most of the major airlines today have code sharing partnerships with other airlines, and code sharing is a key feature of the major airline alliances. Typically, code-sharing agreements are also a part of the commercial agreements between airlines in the same airline alliances.  - Olympic Airlines ("Olympiakés Aerogrammés"  OA), formerly named Olympic Airways for at least four decades, was the flag carrier airline of Greece with their head office in Athens.
