We will be in Greece late May/early June 2018 and want to fly from Athens to Santorini and then from Naxos back to Athens. I understand that there is some period of time when flights go on sale. I have signed up for their Miles and Bonus membership but have never received an email from them (at least in US once a business has your email you will receive lots of correspondence) And I can log on to both sites successfully so do have a membership. I even emailed them but never got a response. So I am guessing I won't receive a notification of a sale. Thus my question as to when prices are likely to be discounted for May and June so I can make sure to check every day.
