I am sure when RPG sees this she can advise ...
Same as SkiathosLover1
WE go to Skiathos every other year from Seattle. Normally we go to London, then Athens, and then the short hop over to Skiathos. WE are going there that way this year, but are coming back by Condor Air. They go Seattle-Frankfurt and then Frankfurt to Skiathos. Days are limited but it is a great connection. Condor is expanding beyond just being a traditional charter flight. I know they also fly out of Portland, Vancouver and I assume other cities in the US.
Well done, we get people here getting stressed about making a 3.5 hour flight and changing in Athens. You fly a third of the way round the world to get to the island.
Condors UK branch (Thomas Cook) have had offers on UK/USA flights too ...
