We have booked direct for the past 4 years and 10% is the average increase every year. Flights need not be expensive if you are flexible about the time of day you fly. We prefer to get the 6am flight with Air2000 so we arrive in Plakias about 2pm. It means we can have a late lunch, a couple of beers, stock up with essentials at the supermarket and unpack before a drink on the balcony and finally dinner. This does of course mean we pay a premium for the flight and it cost £215 each last year (when you book direct). However, even taking that into consideration it still works out cheaper than going with one of the tour operators. It also means less hassle at the airport when you arrive because you are not kept waiting for everyone to board the coach. A taxi is far more civilised and it is nice to be met by the driver as soon as you have collected your luggage. A taxi will cost about £35 each way.
All in all with flights acccommodation and taxis, it cost about £375 each.
Hope that helps
