Well if it's been posted on airliners.net you can probably discount that information regarding departure times ex Manchester, not saying that it won't happen but no one actually thinks before they post on that site anymore.
If anyone has been on those forums lately I'm sure that your notice that the site has been taken over by child like fantasists with the most unbelievable topics and comments, it used to be such a good site though, it's a real shame to see how it has declined in the last two years or so.
