Have a friend or family member taking a long trip by airplane?
You don’t have to wait until they text you when they land to make sure they’re ok. If you have their flight number, you can monitor them in real time.
Here are two websites that let you do this:
Flightaware:
http://flightaware.com
Flightview:

Even if you don’t know the flight number, the sites let you search for it if you know the origin and destination.
