As we seem to have BP threads for everything else I thought this one might be of interest. Then again I suppose all bets are off if you have 40 "through" passengers as my second segment did today (thankfully I was one of them

)
Decided to purchase a BS fare for a recent flight (seemed to make sense from a cost/benefit perspective v. the alternative anytime fare).
Ended up with A11 and was pleasantly surprised to find my top choice exit row aisle seat open - apparently the earlier boarders were infrequent travelers who simply sat down in the first available rows.
So, A11.
