Is there a website out there allowing us to follow a particular aircraft in its consecutive routings?

I envision a site where members would put in the aircraft registration number, date time flight number and seat configuration ( i.e. suite-no suite) etc.

Example: This morning I was on a 747-400, LAX-DEN. First suites on board. The aircraft was going back to LAX, and will be used for LAX-AKL tonight.

This would help circumventing the tired old line from UA reps;

"We have no way of finding the configuration of the aircraft..."

Do I need a real job?
