Thanks folks,
no we are staying on in Athens for a few days,Its just the first night at the hotel there I'm concerned about
in the unlikely event that it happens, Its even more unlikely to happen on the day of travel, correct?
So worst case scenario is you'd be put on an earlier A3 flight?
Would A3 book you onto another carrier that evening if there were irrops or something after checking in?
Just covering bases here so I know what to do if something goes wrong, which knowing my luck might 😱

Thanks again
