Currently I have a similar setup but the data is sent to FlightRadar24 and you get a $499.99/year Business subscription for free for doing exactly this (but sending the data to them).

So, the question I wanted to bring up (and might be controversial) is to know what the differences between the two are? Taking a quick look around it does feel like FlightAware has a lot more openness to it than FR24, which is interesting for me, but I am interested in other opinions on this?

I mean, getting the subscription for pushing the data is always a nice bonus, kinda tempted to just push data to both, and have another Pi sitting in my loft!

Personally, I love just being nosey and seeing the flights around my area, but I am just a bit strange like that ;)
