Summer! That time of year where you stay in somebody else’s home via Airbnb, crank up their air conditioning and wear a sweater in the house, even though it’s 90 degrees outside. Aka the season where you leave the limitless comfort of your home Wi-Fi, to venture out into the world using just a restricted cellular plan.

Summer revives that old pioneering spirit of hardship, the bare essentials of living, and of making do with whatever you have. And just like the original English and Spanish invaders of the modern-day United States, you’ll have to do without the comforts of on-demand GPS and automatic app updates.

Today we’ll see how you can stretch your meager data allowance while traveling.

You need to get organized, and here’s one great way to do it.

It’s Christmas season, and you know what that means: Extra-long queues at airport check-in and “security;” once-a-year travelers who won’t just get out of the plane’s aisle and just sit the hell down; and of course parents/kids/friends who insist that you never emailed them the details of your flight.

We can’t fix the queues, the morons who mill in the aisles, or your lying friends and family, but I can show you how to quickly track a flight right from the Messages app, or anywhere else you see a flight number written down on your iPhone. Let’s take a look.

Tracking flights is a bit of a pain. Siri can do it, and if you’re a real plane spotter, you might even trouble yourself to find an app to do it. But for most of us, we track a flight once in a while, whenever someone’s coming to visit. We just want something that is simple to use, and the disappears. That something is TodayFlights, a neat app that adds a flight tracker to the Mac’s Notification Center Today View.
