LCY8737 still enjoying this resource, thanks again for putting it together.
A couple of observations and suggestions for long-term improvement if I may?

1) When landing on the front page, there is a list of noteworthy movements. I notice that some of these say XXX - Redhill (KRH) when it seems that it should be LGW (I assume there is some mapping issue or it is working based on co-ordinates and KRH is near?)
2) Under the flight analysis pages, it's not possible to view details of flights from one specific airport. For example, if I want to see details of all flights in a date range, I can do so, but this lists EVERY BA flight. it would be good to view by entering the start airport at the bottom, then allow a wildcard entry in the destination to filter that way
3) Linked to this, if looking at the departure gate analysis, the output table doesn't distinguish between terminals, so it aggregates departures from (for example) both LHR T3 gate 31, with LGW gate 31.

Not sure how easy any of the above are to change, but anything you can do, I think will enhance an already great resource.
