I love "meaningless solo trips somewhere", anywhere these days! There are so many permutations of points/miles in this game now that you can't take anything for granted. Even if it's "OK" right now, it may not be in 3 months. I'm an advocate on a travel forum here in the States, and we get a complaint of mileage-earning on partner airlines at least once a month. Previous to the virus disaster, of course. Even if you're super diligent in the research, things can go south and there's little to be done after the fact. For those reasons, I book as few code-shares as possible. As mother would say, "Govern yourself accordingly" ... book with the thought in mind that some parts of the trip may not get you much mileage.
