Perhaps I phrased the question poorly. What I was trying to ask was how often a flight from Heathrow to Newark filled to the point that there were no adjacent seats remaining when it became possible to choose seats without a fee. The answer to that question exists, although perhaps no one on FlyerTalk has the answer and is willing to share it. Nonetheless, if I don't ask, it is almost certain that no one will answer it.
