If you’re planning to fly to Greece on the 5th October… here’s a hint – start planning alterntives as Greek ATC is due to go out on strike that day.
Aegean Airlines has already killed their entire programme of flying on the 5th October http://en.aegeanair.com/all-about-us/press-office/press-releases/press-release/?prid=324, whilst Olympic has not made an annoucement yet. EasyJet has posted it’s thoughts at http://easyjet.custhelp.com/app/answers/detail/a_id/3970/~/current-travel-status
If the strike goes ahead expect chaos and start replanning NOW.
