Aegean Airlines Miles&Bonus - Any way to get into Aegean lounge if biz class not offered on flight?

We will be arriving into Athens from Rome and will then take Aegean Airlines to Mykonos over three hours later. The flight to Mykonos is a regional jet that does not offer business class, which I was wanting so we could go to the lounge. Other than flying in biz, is there another way we can get lounge access?

Aside from asking Aegean whether a full Y class tkt will get you into their (very nice and shiny but not that functional) lounge, the best option (and one likely to be cheaper than the $60 difference between cheapest and full eco) is to go across the road to the Sofitel and use the bar...It's quite a nice place and every staff member I've come into contact with has been wonderful! :-:

We will be flying from Rhodes to Athens on Aegean then taking Olympic to Naxos (Aegean doesn't fly there). There were no good corresponding flight times, so we will have around a 4 hour wait in Athens. Olympic does not offer business class for the flight to Naxos, so that option is not available to get lounge access. Is there any other way?

Edited to add: I have a Delta Crown Room membership, but I don't believe that there is either a DL, NW or CO lounge in the Athens airport. Is there another lounge that would honor my CRC membership, even if it cost an entrance fee?

Can't talk about your chances, but officially you have no access.

Aegean is not *A. So you cannot use their lounge. Unfortunately you can't use the SEN lounge next door either, since you are *G albeit not departing on a same day *A flight.

Can't talk about your chances, but officially you have no access.

Sadly, that's the way I read the rules :(
