Flightradar24 - NOT amateur radio

Our younger son is returning from a few weeks with his in-laws who live in Australia. They had a few nights in Dubai to break the journey otherwise it is a very long way! 

We can track the trip with Flightradar24 which is a free app paid for by adverts. With a paid subscription you can get extra features.

See https://www.flightradar24.com .  There are a number of very similar named apps. Be sure to get the correct one!
