Making use of a Wi-Fi connection on airplanes is pretty commonplace these days as virtually every airline offers a connection, making long flights more productive. But keep in mind that everyone else on the flight is sharing your same connection, so it's never going to be a very fast pipe, but it's generally better than going without it. Since we tend to travel with a lot of devices, it's nice to connect them all the same time, but who wants to pay an extra charge for each gadget? When you're in that situation, remember that a laptop can easily be turned into a wifi hotspot so you can share that expensive connection to the rest of your devices. Mac and Windows computers both have the ability to use Internet-connection sharing so you can also connect to Wi-Fi on your smartphone and tablet for the price of one device. It's not just useful on airplanes because many places will charge you by the device for their Internet connection, like a hotel. Windows user
