Yes, okay it’s alphabetical order but like others, probably the minority, I type airport codes. But non-airport destinations should not come up anyway. And I believe way more people probably fly IAG LON - MAD than the others

At least Madison and Madagascar come up as available sales on BA’s website. Not surprised by MSN but was that TRN, on sale using Kenya Air, Sky Team member. I wonder if you get/can redeem Avios on that route!
