Is your itinerary all on TG flights? If so there probably is not solution.
I am holding a UA/MP issued *A award ticket with segments on TG and LH. When I use the LH reservation code I can view my itinerary at checkmytrip dot com, including the TG segments. The level of detail on the LH segements is impressive, including a hotlink to a live seatmap. For the TG segments the information is limited to Status: Confirmed, Cabin: First, Stops: 0.
