FTFY, sorry, but do you know how this works?
I didn't say 2BM would work. I just fine tuned the analogy.
You can go one day and there's only one seat at the lowest fare and you book the second seat paying a little more, only to see the next morning that there's again one seat available at the lowest fare. It's not like there were no seats available, but none allocated to the special price (using the milk analogy) that can change by the manager, without having to get any additional inventory delivered.
