We've rounded up all the info you need to make your journey as stress-free as possible. Follow our tips and you'll be cruising through airport security and exploring South Portland in next to no time.What to pack in your hand luggage:

• Flying can be a great experience if you pack the right things. Firstly, you'll need toiletry items, such as a toothbrush and some deodorant, a clean pair of socks and a good read. Secondly, find room in your hand luggage for your phone and charger, any daily medications and perhaps a cozy neck pillow too. Lastly, remember to bring your passport, travel documents and your credit cards.

Do not pack the following items in your hand luggage:

• Squeeze all your full-sized bottles of shampoo and hair gel in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 milliliters) will be confiscated by security. Sharp objects, like your precious Swiss Army knife, and dangerous products which are flammable or explosive, such as flares, chemicals agents and strong acids, are also restricted.

What to wear on a flight:

• The goal here is to feel as comfortable as possible. Don layers of natural fibers and remember to bring a pullover in case you get cold. Always go with flat, slightly roomy shoes as it's possible that your feet and ankles will swell during the flight. Leave the stilettos and hiking boots in your checked baggage.
• Most travelers have heard about DVT (deep vein thrombosis), a blood clot condition caused by long periods of inactivity. There's lots you can do to reduce your risk. Wear a good-quality pair of compression socks or tights, stay well hydrated and keep your legs and feet moving. Walk the aisles of the cabin or try out some exercises in your seat.

The answer is simple — be prepared. We've put together some helpful hints for a fuss-free trip through airport security. Look out South Portland, here you come:

• Security personnel first need to see that you have a valid passport and matching boarding pass before you can proceed any further. Have them ready for inspection.
• The X-ray machine is up next. Remove anything metal on you that is likely to set off the scanner's alarm. This includes items like earphones or headphones, as well as your coat or jacket. They'll need to be placed on the conveyor belt for screening.
• For just a few moments, you'll need to unplug from the digital world. Your laptop, phone and any other electronics will need to be sent through the scanner.
• Remember to remove gels and liquids from your carry-on bag. They usually need to be sent through the X-ray separately. Each product should be no larger than 3.4 ounces (100 milliliters) and everything must fit in a quart-size (one liter), clear zip-lock bag.
• It's also possible you'll need to remove your shoes to be X-rayed, so wearing slip-on sneakers is always a clever idea.
• Sharp items such as knives and scissors are prohibited in the cabin. They'll be confiscated at security, so pack them safely away in your checked bags.
