There was more bad news for beleaguered Greece, as two more German travel firms said they were seeing a 30 percent drop in bookings to the Mediterranean nation.
Reports of animosity and even violence towards Germans over the hard austerity measures demanded by Chancellor Angela Merkel in return for bailouts, as well as fears of strikes, are keeping the world's biggest spenders on foreign holidays away from Greece.
Air Berlin, Germany's second largest airline, and Rewe, the retail and tourism group both said that bookings to Greece were around 30 percent below that of last year.
Tourism is a vital source of income for Greece, accounting for about a fifth of gross domestic product.
"Greece is doing very badly, just like North Africa," Air Berlin chief executive Hartmut Mehdorn said.
Rewe Tourism chief Norbert Fiebig said Germans were instead choosing to travel to other places such as Turkey, echoing comments from Thomas Cook Germany, which has said Spain is also proving a popular alternative.
Other travel groups such as TUI and Thomas Cook's Germany-based airline Condor have already announced offers and discounts to try to stem the fall in bookings.
