Using the Private Flight Tracker feature it’s actually possible to enter a tail number/registration number of most US airliners and find the latest flights. However, I want to do the reverse. i.e. key in the Flight Number and get the tail number/registration. If Flightaware knows both pieces of data why can’t I find what I want?
I’m also trying to find out the tail numbers for Allegiant flights into MBS last year. The 'BTS website doesn’t seem to list Allegiant flights but these would be on Flightaware somewhere wouldn’t they?
