Ah. Well, in that case it's not a question of whether LX is "strict" or not.
LX will simply transport the pax in the cabin that the original operator - UA - has rebooked the pax in. Same with any other airline.
If UA is willing to do (UA Y tix + GPU) = LX revenue Biz class, then the pax will fly in Business.
If UA does (UA Y tix + GPU) = LX revenue Economy class plus a good wish, then the pax will fly in Economy.
