Can we include an additional leg after the trip has originated? Basically planning ABC -DEF - XYZ-ABC but am not sure about the DEF - XYZ date and hence trying to keep that fluid. ...
It would effectively become a new booking and new availability for all legs will be needed. If you call UA, the previously booked UA segments can be re-used. Partner new availability is the problem, Some have been successful reusing LH legs but no guarantee that you will not lose the original award trying to add the Excursion segment
