Where to organise greek island flights from Athens?

Hi,

What is a good web site to go to to look at planning my flights to the
greek islands.

Also, anybody help with which islands are best served in
October/November - for regular daily flights and for the island not
closing up after the summer holiday (if this happens at all!)

You can buy tickets from Travelocity.com, Expedia.com, and Sams.com. The prices
are pretty much the same at all three. I'm sure there are other places where
you can buy them, but the tickets are pretty cheap to begin with, so there's
not much of a discount possible.

One caveat though: If you do purchase tickets for Olympic flights, I would
recommend calling Olympic directly after you purchase your tickets to confirm
your flight. I had an unfortunate incident a couple months ago when Olympic
issued a ticket through Sam's but didn't actually have a seat for me.
Fortunately I found out in time to change the flight, but it was quite a
hassle.
