I wasn't sure if there are any "free" or "automatic" upgrades on international flights with any status (maybe Global Services?).
No, but GS and 1K can use the GPUs they receive when they qualify for those status. For 1K not all fares qualify for using the GPUs. I think the cheaper one that qualifies is W. I don't know about if there is such a restriction for GS.
I see that I typed too slow and
goodeats21 had already given a detailed explanation.
