I like the new layout Thanks to those that did the hard work. This wiki isn't going to suit everyone but it is a good resource.
Might I suggest that at airports that get BA flights from multiple BA destinations (e.g. AMS) that a note is added that the traffic lights only apply if you are doing a true B2B and not e.g. an inbound from LCY and an outbound to LHR. I know that wouldn't be a trye B2B but we have had questions about this in the past.
