Was flying FRA-WAW-SVO yesterday on a flexible LOT economy classs ticket (sales code MGOLD, booking into M), however FRA-WAW was operated by LH and WAW-SVO by SU.
Boarding pass for FRA-WAW showed LH booking class P (750 miles instead 1250 for LO M), booking class on SU for WAW-SVO was Y (I know there won't be any miles for me).
Was quite surprised about this M >> P, as P is not a flexible booking class on international segments with LH.
Any insights from the experts?
Thanks,
Thomas
