Some travelers are blessed with the ability to fall asleep on a flight as soon as their seatbelt clicks into place. But for many of us, it takes ginger ale, Dramamine, an eye mask, fan, and music or movie marathon to lull us to sleep. And staying asleep until wheels down? Now, that's a whole other beast. However, aviation and sleep experts say that scheduling nap time in the middle of a flight could be to your benefit.

For nearly as long as commercial air travel has been possible, flight attendants have pushed back on policies surrounding their appearance and what they have to wear. It used to be about miniskirts and hot pants; today it’s about tattoos, comfort, and gender-neutral clothing. No matter the specifics, the shifts in airline uniforms reflect shifts in culture, and if you look to the skies, you can see that change happening yet again. In recent years—and even this past month—airlines worldwide have increasingly been loosening once-strict appearance guidelines and dress code policies to become more inclusive.

When checking into your flight, have you noticed a prompt asking if you'd be willing to change your trip? Alternatively, you might have heard an announcement at the gate asking for volunteers to take a later flight. Yes, it's true — most airlines overbook their flights. Booking a plane ticket doesn't actually guarantee you'll have a seat on that flight. So, why do airlines have this practice?

Looking at an airfield you might notice that almost all the aircraft are painted white. But do you know why? And no – it’s not to blend in with the clouds that surround them.

There's a reason passengers might hear a “barking” noise during a long flight – and it’s got nothing to do with dogs. During a flight an aeroplane might make various strange noises which might unsettle nervous fliers but invariably they are nothing to worry about.

Many might feel scared to fly following recent incidents of severe turbulence, including on an Air Europa flight Monday that injured 30 people, but experts have assured Newsweek larger planes can handle the extreme conditions.

Whether you're a first-time flier, a nervous flier, or a curious frequent flier, you might have questions about all the noises you hear during a flight. And no, we don't mean babies crying or the jarringly loud drop of an iPhone.

If you've ever booked a flight, you're probably aware every airport in the world has a three-letter code. It's not surprising airports would have such an identifier, since it's easier to say and write than a full name. "Brevity on the radio is important, especially in busy air traffic locations," former airline pilot Dan Bubb, a professor at the ��ҳ| �鶹��ýӳ��, tells Travel + Leisure.
