JayPS,

IMHO you are fully correct. You can have TG segments in your routing and still benefit from the companion award as long as your companion does not have these TG segments in her booking. I did book such a companion award myself last December for travel in April of 2011. I fly FRA NYC SFO ORD FRA, with LH on the transatlantic legs and UA on the others. My companion flies just the LH legs FRA NYC and ORD FRA (and paid tickets within the US). I got the 50% rebate on my companion's ticket.

Aside from that LH did sell you your tickets under certain conditions and they cannot come back later and try to charge more, even if the rules would have changed. I would call them again and be very firm. Ask for the supervisor and insist on your position.

Good luck!!

Have safe travels
