Cheap Flights to Portland from HK$1,136

Wherever you're jetting in from, flying can be a pleasurable experience if you've prepared well. We've made a list of handy hints that will help get your Portland escape started on the right note. What to pack in your hand luggage:

• It's easy — first, put in your passport, official ID, bank cards and vital medications. Next, you'll need some extra in-flight entertainment to while away the hours. A juicy novel and a phone filled with your favourite shows are some fantastic options. If you hope to take a quick nap, a quality neck pillow and a pair of earplugs will also be useful. Finally, leave space for a toothbrush and some deodorant to ensure you arrive at your destination feeling fresh as a daisy.

Do not pack the following items in your hand luggage:

• Put all your full-sized bottles of hair gel and hairspray in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Sharp or pointed objects, like your precious Swiss Army knife, and dangerous goods which are explosive or flammable, such as spray paint, flares and strong acids, are also restricted.

What to wear on a flight:

• Go for comfort over style. Prepare for changes in cabin temperature by dressing in layers, and wear flat, slightly roomy shoes like slip-ons.
• You're probably aware of deep vein thrombosis (DVT), a blood clotting condition caused by long periods of inactivity. To lower your risk on board, drink plenty of water, consider wearing compression socks and keep your feet and legs moving.

The simple answer is — be prepared. We've pulled together some handy tips and tricks for a hassle-free trip through airport security. Look out Portland, here you come:

• Airport security personnel first need to determine that you have a valid passport and travel documents before you're allowed to proceed any further. Have them in your hand, ready for inspection.
• The X-ray machine comes next. Remove anything on you that is likely to set off the scanner's alarm. This includes things like earphones or headphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
• For just a few moments, you'll need to unplug from technology. Your phone, laptop and any other electronics will also need to be sent through the scanner.
• Any liquids or gels, such as perfume or hairspray, that you want to take on board must be no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
• There's a possibility that you'll be required to remove your shoes to be X-rayed, so wearing slip-on shoes is always a clever idea.
• Sharp items such as knives and scissors are not allowed on board. They'll be confiscated at security, so pack them safely away in your checked bags.
