Prior to the pandemic I'd almost always book my flights with Aegean via various OTAs and not once did I get anything greater than the absolute minimum amount of miles of whatever the lowest fare type would have been (now "light", previously "go light" an so on...). The fact that all of pbd456 's flights were actually operated by Aegean makes this even stranger (as a mixed carrier ticket would absolutely justify the ticket being issued in some fare type that Aegean doesn't even sell on their own website). However I'd like to see those app screenshots if possible, since my Aegean app never shows the ticket type, just the booking class (U, T, P etc.) and there could be some cases of a higher booking class crediting as light and post miles that would resemble a lower booking class posting as flex (for example LHR-ATH in H and the other 3 legs in S, all 4 in "Light" would result in exactly 3008 miles...!).
