Hi Nick,
There aren't commonly available flight tracking plugins like the boat tracking ones you mentioned.
However, there are some popular flight tracking websites that you can use to see real-time air traffic. These sites allow you to filter by airline and flight number in many cases. Here are a couple:
- live flight tracker
- Flightradar24
- FlightAware
These sites are pretty user-friendly, so you shouldn't need any IT expertise to use them.
