Lufthansa Miles&More members can now earn miles for flights taken with Aegean subsidiary Olympic Air that is not part of Star Alliance.
United Airlines and Air Canada frequent flier program members have been able to earn miles for Olympic Air flights previously in addition to Aegean Miles+Bonus members. Olympic Air flights are not eligible for Star Alliance elite status benefits, however.
You can access Lufthansa’s page for Olympic Air here.
Here’s the Lufthansa’s Olympic Air information:
Aegean has this Olympic Air subsidiary almost only to exclude all those Star Alliance Gold members of their benefits and collect bag fees for intra-Greece flights. Miles+Bonus elite benefits do apply for Olympic Air flights.
