That'd be awesome. BTW, some flight tracking services do show detailed information about the airplane, like service time (age), etc... I might give it a try
If you know the flight number and name of airline and aircraft make -- do you also get the Aircraft (ID?) -- such that you can see ALL the routes . this plane has flown over the last N period and know how many flight hours and miles it has under its belt for some period?
You could then calc the downtime that the planes get for maint/cleaning/etc...
SeatGuru Link to this plane + airline combo would be the most useful.
