Cheap Flights to Katerini from HK$408

If you're not prepared, airports and flying can be tough. But there's no need to panic. Follow these handy tips for a comfortable start to your vacation in Katerini.What to pack in your hand luggage:

• First of all, pack in your passport, travel docs, wallet and daily medications. Next, you'll want some extra in-flight entertainment to help pass the time. A thrilling book and a phone filled with your favorite shows are always good options. If you plan to catch up on some sleep, a neck pillow and some earplugs will also be useful. Finally, leave space for a toothbrush and some facial wipes so you'll hop off the plane looking fresh and raring to go.

Do not pack the following items in your hand luggage:

• Squeeze all your full-sized bottles of hair gel and hairspray in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated by security. Pointed or sharp objects, like your Swiss Army knife, and dangerous products which are flammable or explosive, such as aerosols and poisons, are also not allowed.

What to wear on a flight:

• The goal here is to feel as comfortable as you can. Don layers of natural-fiber clothing and pack a jacket in case it gets cool in the cabin. Pick a pair of roomy, flat shoes as it's possible that your feet and ankles will swell a little during the journey. Leave the high heels and chunky boots in your checked baggage.
• You've probably heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of sitting. There's plenty you can do to minimize your risk. Wear compression tights or socks, drink lots of water often and remember to keep your legs and feet moving. Do a few laps of the cabin or perform exercises in your seat.

It's easy — be prepared. We've rounded up some top tips for an easy trip through security. Watch out Katerini, here you come:

• Be sure to have your boarding pass and ID easily accessible. They're the first items you'll be asked for by security.
• Next up, both you and your carry-on luggage will be X-rayed. To speed things up, take off anything that might trigger the alarms. Items such as your belt, coat and earphones will be required to go through the machine.
• All your electronics, including your tablet and phone, will also need to be scanned.
• Remember to remove gels and liquids from your carry-on bag. They often need to be sent through the X-ray separately. Each product should be in a container no larger than 3.4 ounces (100 milliliters) and everything must fit in a single quart-size (one liter), clear zip-close bag.
• Choosing your footwear wisely can save you valuable minutes. Hiking boots are often required to be removed and X-rayed separately. Slip-on sneakers usually aren't.
• Airlines will not allow any sharp objects in your carry-on baggage. If you need to bring these kinds of items, pack them in your checked baggage.
