For purchases at the Hellenic Duty Free Shops from June 17th 2016, the retroactive credit of missing miles will not be available, thus the member must show the Miles+Bonus card during the transaction, otherwise the miles will not be credited. Retroactive missing miles requests will be accepted for purchases from June 17th 2015 to June 16th 2016, by sending the purchase receipt to Aegean, by email to https://aegeanairlines.custhelp.com/app/ask.
