Lufthansa partner Airline Air Dolomiti United Credit
Is it possible to earn miles in a Star Alliance partner program (United Airlines Mileage Plus) while flying on a Lufthansa Flight operated by Air Dolomiti?
They say: "We received your request to credit your MileagePlus® account with the flight on February xxx, Venice to Munich. This flight was a code-share flight where Lufthansa had marketed the flight, but Air Dolomiti was the operating airlines. For a code-share flight, the miles are determined by the operating airlines. We are unable to credit your account because Air Dolomiti is not one of our partners."
My understanding is that Air Dolomiti is not a code-share partner of Lufthansa but totally owned by Lufthansa and part of Lufthansa Regional as much like Eurowings. This should come with full Star Alliance benefits right? they had for example pre-boarding for Star Gold.
