If I can continue to pull from your thread...
Diamond has only seemed to pile issues from other *A carriers, particularly Air India and TK (just recently).
What do you put in when flying with other *A airlines? EBG1718xxxxx, EBD1718xxxxx, only 1718xxxxx?
Tough to use when it changes based on the carrier, so looking for some form of consistency (if that exists with SK)
Reading other threads on FT, agree with others that SKs loyalty programs are a bit sub-par, but seems others might be looking a bit elsewhere too.
