FlightAware has a data center in London and has been providing flight
tracking services in Europe for a few years now. They have a service
of some sort that provides them with flight plan data in Europe, but
have moved away from the delayed tracking data there just like they
have in the states. Majority of their tracking data is now live and
comes from their network of thousands of ADS-B feed sites around the
world (map of coverage area available in the ADS-B section of their
site).

True, but there are circumstances where Planefinder doesn't help at all.
A little background info... FR24 has been using MLAT to provide
tracking everywhere possible for non-ADS-B aircraft for a while now.
As of a few weeks ago, many of us that feed ADS-B data to FlightAware
(I feed both) have been testing MLAT behind the scenes and it should
be live soon. This will provide FlightAware with another near-live
method of tracking other than ADS-B (just like FR24) and won't leave
them dependant on delayed FAA tracking data for non-ADS-B aircraft
anymore.
I came across the perfect example of how MLAT tracking is quite handy
just yesterday when a friend asked if anyone knew where a foreign
Learjet 40 (M-LRJT) was going after departing from ATL. While FR24
didn't actually link the tail number to the aircraft on the map, it
only took a matter of seconds for me to create a quick filter for all
LJ40 aircraft currently being tracked and find the bird that had
departed from ATL. It's not an ideal method of tracking aircraft that
aren't showing up otherwise, but it can work if you know that a
blocked bird departed from a specific airport and can find the same
aircraft type in the air showing that it departed from that airport.
Planefinder, which isn't making use of MLAT tracking in that area
(apparently), didn't show the aircraft on their map at all as it
wasn't transmitting ADS-B data. See attached screenshots...
