I was just looking at my bookings on LH's site and on the initial overview page is the comment "Offline Prämien Upgrade". When I look at the booking, two of my segments MUC-VIE and ZAG have the comment "EA" as opposed to the other segment which states "Economy Class Best Buy". It was an offline flysmart award booking.

Does this mean that I have been chosen for an upgrade on those two segments or should I understand the comment as "Offline Prämien/Upgrade" with the "/" meaning "or"? I would expect all of the segments to have the same comment, if the latter is the case.
