Stop downvoting me unnecessarily. I am stating my reasoning of avoiding London airport, and it makes reasonable sense. Similar thing has happened to London ATC before, as per the video report in the article, where a new upgrade to the software disrupted flights last year. Together with all the Iceland volcanoes etc., my reasons to avoid this airport are all legitimate. Even if you have other choices, you don't need to downvote me.
