Those who are planning to take a vacation in Greece are canceling their bookings due to the economic crisis in the country, affecting most airline companies. Several airline companies, including Turkish Airlines (THY), Emirates and Qatar Airways, have stopped allowing Greek travel agents to sell their tickets, Lysandros Tsilidis, the president of the Hellenic Association of Travel and Tourist Agencies (HATTA) said. "We consider this inexcusably tough. Even though they have been our partners for years and even though we have already paid 82 percent of what we owe to them during this season," said Tsilidis. Turkish Airlines and Emirates confirmed they had stopped issuing tickets through Greek tour operators and travel agents. Emirates said its customers could still book tickets for its flights via its sales office in Athens, on the phone or online. Governments have advised tourists visiting Greece to bring euros in cash for spending money because of the capital controls imposed since June 29, which limit withdrawals from cash machines and payments abroad.
