最近这事处理有些进展，回报一下以供参考。
我大约4月20日左右在Aegean网站去claim这些哩程，然后约五月中旬成功跟UA要求移除
这些被UA抢走的哩程。
然后六月十二日收到Aegean的email:
We thank you for contacting the Customer Relations Department of Aegean and for
your preference to us.
Regarding your retro claim on BR17 , kindly be informed that the operating
carrier rejected the mileage accrual notifying that the miles are already
credited to another airline’s loyalty program.
We remain at your disposal for any further detail you may need.
Best Regards,
