The Eleftherios Venizelos Athens International Airport’s (AIA) data and the data of hoteliers found that ten percent of passenger traffic was unaccounted for as it did not end up at a hotel. The study lead to the conclusion that the missing ten percent of those who came to Greece but did not use accommodation as they were among the masses that left Greece as a result of the economic crisis. The rise in Greeks living abroad means that many of them return to see their loved ones, but do not end up at a hotel, choosing to stay in the homes they left behind.
In 2015, there were 620,000 transfers of Greeks abroad, whereas in 2006, there were 295,000 people. In nine years, there was an increase of 325,000 passengers through the AIA. Twenty percent of the people passing through the AIA were ex-pat Greeks, whereas 80 percent were foreign visitors. The total number of arrivals was at the record number of 3,200,000 people.
In 2006, the number of transfers of Greeks abroad via AIA was 295,000, just 12 percent the total transfers, whereas 88 percent had to do with the transfer of foreigners. The doubling confused authorities examining the data as they saw an increase in airport traffic that did not translate to an increase in hotel guests.
