Slavish?

Anyway, I didn't say you can't give your upgrade to a traveling companion - I said you should not give your upgrade to a total stranger so you can sit with a travel companion who did not get upgraded. If you want to sit with someone in Y, tell the GA you don't want your upgrade and will sit in Y - see if they can find a seat with, or near your companion (or trade when onboard), and let the GA upgrade the next Elite on the list.

Plenty of posters here have given their upgrade to a spouse and sat in the spouse's seat in Y - there is nothing wrong with doing that, and as any married person knows, it's probably better for your health and safety to let the wife sit in F.
