Turbulence can range from annoying to downright frightening, and you don't have to be an anxious flyer to get worked up by it. It's hard to avoid turbulence when flying, but you can control how you handle it.

Many people are required to travel as part of their job. Work-related travel might be something as simple as a short trip to see a client for an hour or two or a prolonged trip lasting several days interstate or even overseas. Some of these travel expenses can be claimed at tax time - but you need to know which rules to follow.

One of the most tedious aspects of overseas flying is filling out that annoying green card prior to departure. There are never enough pens to go around and you usually forget your flight and/or passport number. Ain't nobody for time for that!

Well, it appears the Department of Immigration and Border Protection (DIBP) agrees. From July 1, you will no longer be required to fill out these pesky cards while passing through immigration. Hurrah!

Google Flights is a solid tool for booking travel. You're probably already familiar with its basic functions, like finding the best price for flights and browsing flexible dates that can save you money and time. However, there are some other, lesser-known features that can help you squeeze even more out of your travel budget.

Google Flights, the online search engine for comparing and booking airfares, is now available in Australia. The service instantly serves up the best flight options and prices based on your destination and travel dates. Here's how it works.

Most of us tend to overpack when we travel. You might as well toss in those extra shirts, chargers and camera gadgets because you never know what you might need, right? Of course, you then end up not using half the stuff you bring. If this sounds familiar, consider a "luggage audit" next time you travel.

It's annoying as hell when you have your tray table down, trying to work or eat, and the person in front of you reclines, narrowing the already tiny gap between your knees and their seatback. To retaliate, you recline your own seat — it's your right, after all — and annoy the person behind you. It's a frustrating domino effect of travellers trying to reclaim their space. So who owns that space to begin with?

Sometimes the best things in life are right in front of you but go unnoticed. Take, as today's example, the little hook on aeroplane seats. During a recent flight, my seat neighbour took off her cardigan and hung it on the hook. My mind was blown and I felt silly for not realising this hook had a purpose.

Flatulence is common when you're flying. The BBC explains the science of why we fart more on aeroplanes and offers some tips on reducing this discomfort and avoid being that person passing gas on the plane.

Life gets pretty exhausting if you're always afraid of getting dirty. I try to remember this mantra when I fly because aeroplanes are so freaking filthy. Research from the University of Victoria suggests we're 100 times more likely to catch a cold from air travel than "normal daily ground level experience". Here's how to stay relatively sanitary (and sane) on planes.

Cheap air travel isn't as awesome as you think it is, namely because it makes air travel suck more overall. Believe it or not, though, air travel has improved in some ways, too.

Qantas has revealed the pricing for its first direct flight between Perth and London - and the tickets go on sale today. A non-stop return Economy flight to London will officially set you back $2270, although Qantas is promising prices below $2000 during promotional periods. Here are the details.

Everyone is horrified by how United Airlines has treated a paying passenger it decided to kick off a plane after he had boarded. One minor but chilling aspect of the horror? How United's own comments abuse what language actually means to try and justify its shitty behaviour.

Today, the world woke up to a very disturbing video of a United Airlines passenger being bloodied and dragged off an overbooked flight so that a United employee could fly in his place. The footage has caused outrage with numerous calls to boycott the airline. Many have pointed out that the man was a paying customer who posed no threat, so the airline had no right to forcibly remove him.

There's no question that what happened to this passenger was completely over the top. But on a technical level, it was also entirely legal to eject him. It turns out airlines can kick you off a flight for all sorts of reasons. Let's take a look at the facts.

There are good airlines and there are the many other airlines. This infographic from AirHelp sorts the best from the worst with an emphasis on timeliness and compensatory measures when things go wrong.

While there's never truly a "good time" to use the toilet in a crowded, cramped metal tube hurling through the sky at 805km an hour, some times are more comfortable than others. Here's what a professional flyer recommends if you're worried about privacy and being considerate to other passengers.

When you pay for in-flight Wi-Fi, you typically have a few options. You can pay for a day pass, just pay for the duration of the flight, or pay for 30 minutes at a time. If you have a connecting flight with the same airline, a day pass on your first leg might be a cheaper option.

Frequent flyer points are a fantasy currency that fluctuates depending on how you use them. This makes it difficult to know what they're worth — or whether you're squandering their potential value. This infographic breaks down the dollar value of 1000 points when purchasing everything from flight upgrades to commercial goods.
