Does anyone know of an airline that would fly direct from London to Santorini?

You can find charter flight options at www.firstchoice.uk.co/flights.

I don't believe there are any direct flights from London. Check with easyjet, if not then you should fly through Athens. The airport in Santorini is a tiny one.

There have been direct charter flights from London to Santorini for years, at least since 1987 when I picked up a friend who came in on just such a flight. The airport is not that small anymore. Try using the links on this website to help find what you need. Google "London-Santorini Charter Flights"

The airport code for Santorini is JTR

Apart from charters, Exel Airways does scheduled nonstop flights to Santorini from Gatwick, Manchester and Newcastle.

I can't imagine why anyone would think Easyjet does the route.

UK charter airlines fly direct from London UK(Gatwick), try ExcelAirways, FirstChoice Airways, Thomson, Thomas Cook Airways.

You can fly from London to Athens then catch a flight from Athens to Santorini via Olympic Air.
