Bookings from London to Rhodes and Corfu have seen the biggest surge with year-on-year increases of 567% and 270% respectively based on bookings made between January and July compared with the same period in 2014.
Searches for flights from London to Crete have led to a 293% increase in bookings while Santorini is 200% up.
Bookings for flights to Athens are up 255% year-on-year.
UK managing director, Peter Grover, said: “Both mainland Greece and the idyllic surrounding islands are continuing to show incredibly strong booking figures for us this summer.
“The hard work of the Greek tourist board to continue to attract holidaymakers, despite a financial crisis, and the support of airlines and tour operators in decreasing prices to the Mediterranean destination have combined to cause a mega-surge in bookings.”
