As suggested by
lhr baby in another thread
here, this thread can be a resource recording how codeshare flights (a) map across from the marketing carrier to the operating carrier and (b) are credited to Aegean Airlines Miles&Bonus accounts.
It's too soon to say whether there will be enough reports to justify collating and sorting the data at the top of the thread. To be on the safe side I'll reserve another post after this one, trusting that the mods won't object, but for the time being expect the thread to have a classic chronological structure (also known as "find it yourself"
).
First data point:
FRA-LHR, marketed by A3 in booking class K (fare basis K2A3GB), operated by LH, credited as booking class S, 500 miles, June 2012
