Cheap Flights to Khe Sanh from HK$1,371

If you're poorly prepared, air travel can be challenging. But there's no need to hit the panic button just yet. Follow these tips and tricks and enjoy a pleasant start to your getaway in Khe Sanh.What to pack in your hand luggage:

• It's easy — first, pack in your passport, important documents, wallet and medications. Next, you'll want some extra in-flight entertainment to while away the hours. A thrilling book and a laptop filled with your favorite movies are some fantastic options. If you intend to take a short snooze, a comfy neck pillow and a pair of earplugs will also come in handy. Finally, leave some space for a toothbrush and some cleansing wipes so you'll hop off the plane looking fresh and raring to go.

Do not pack the following items in your hand luggage:

• Check carefully that you don't have sharp objects (like a pocket knife) lurking in one of the compartments of your carry-on luggage. Other restricted items include flammable or explosive substances, such as bleach and fuel, and liquids and gels in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

• Comfort should be your prime concern when choosing what to wear on board. Consider your footwear carefully too, as swollen feet are a common occurrence. Shoes which are flat and slightly roomy are always a good idea.
• It's likely you've heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. There are many ways to reduce your risk. Wear a good-quality pair of compression socks, stay well hydrated and move your legs and feet. Do a few laps of the cabin or perform exercises in your seat.

The answer is simple — be organized. We've rounded up some handy tips and tricks for a stress-free trip through airport security. Watch out Khe Sanh, here you come:

• Have your boarding pass and ID within close reach. They'll be the first things you'll be asked for by airport security.
• The X-ray machine is up next. Empty your pockets and remove anything metal that is likely to set off the scanner's alarm. This includes things like headphones or earphones, as well as heavy jackets or coats. They'll all need to go on the X-ray conveyor belt.
• Your electronic gadgets like phones and laptops will also have to go on a tray to be scanned. Don't worry, you'll be back online soon enough.
• Can't travel without your favorite perfume? No problem. As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a clear zip-lock bag, you can keep it with you in your carry-on bag.
• There's a chance you'll be asked to take your shoes off for scanning, so wearing slip-on sneakers is always a wise idea.
• Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, put them in your checked luggage. They won't be allowed on board.
