Okay so I'm currently shuttling a lot between FRA and VIE and looking at the new mileage accrual rules for European cross border flights on LH vs. OS I found this very odd difference which would affect mileage credited for flights between the two countries (I have searched for a similar thread but didn't find one):

LH
Business Class (C, D, Z) 1,500 mls
Economy Class (B, Y) 750 mls
Economy Class (G, H, K, M, Q, S, V, W) 500 mls
Economy Class (L, T) 125 mls


OS
Business Class (C, D, J) 2,000 mls
Economy Class (B, Y) 1,250 mls
Economy Class (E, G, H, K, M, P, Q, S, V, W) 750 mls
Economy Class (L, T) 125 mls

So if this were correct one should obviuosly always try fly on OS as the mileage accrual is 250 or 500 mls better respectively. Exec bonus is also guaranteed. What the heck are these guys at LH M&M thinking ?

Anyone has an idea?

Cheers ...
