Lost Item, How to Track a Plane’s Path
 

I left my iPad on a plane and I’ve filed a missing item report for it at my arrival airport, however to cover my bases I also wanted to file a report at the airport where the plane continued onto in case my item was recovered there. Is there a website where I can get this information? Thanks in advance for any insight!

FR24 is the usual go-to for this sort of search, free for a few days of history, subscribe for months-2 years

Flightaware is also capable of tracking planes by their registration number.

As a broader issue, knowing the carrier, the route, and the specific airport at which you disembarked, is essential information. Some carriers and airports, everything gets turned over to a local L&F. Elsewhere, it is held locally and then sent to some massive warehouse.

If you post your flight information - number and date - in the Historical Flight Data [delays, cancellations, etc., consolidated thread], members who have access to subscription services will generally look the information up for you.
