Cheap Flights to Portland from HK$1,555

Depending on where you're coming from, your trip to Portland could be a piece of cake or it could go on forever. We've compiled some handy tips that will help you start your next great adventure on a positive note. What to pack in your hand luggage:

• Travelling on a plane can be easy if you bring the right gear. First of all you'll need basic toiletry items, such as deodorant and a toothbrush, a spare set of clothes and a magazine or two. Next, make room in your carry-on bag for your phone, tablet and chargers, medications and perhaps a blow-up neck pillow as well. Last, but definitely not least, don't forget to bring your passport, travel papers and your bank cards.

Do not pack the following items in your hand luggage:

• While the list of prohibited items can differ between air carriers, the general rule to follow is avoid carrying anything flammable, sharp or explosive. This includes things like screwdrivers, pocket knives, spray paint and fireworks. Sports equipment like bows and arrows, and objects that could harm passengers, such as swords and guns, aren't allowed in the cabin either.

What to wear on a flight:

• You'll want to go for comfort over style. Prepare for temperature changes in the cabin by layering up, and wear closed-toe, flat footwear like sneakers.
• Deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity, can be a risk on long-haul flights. Try to wander around the cabin or do some gentle exercises in your seat to improve your circulation.

As seasoned travellers know, the secret is to be well organised before you get to the security gate. That way, you'll be stepping onto that plane to Portland in the blink of an eye. Follow these helpful tips and get your trip off to a terrific start:

• Your ID and travel documents will need to be inspected by security personnel. Have them close by to avoid fumbling around for them.
• After that, both you and your carry-on bag must be X-rayed. To make the process quick and painless, remove anything that might trigger the alarms. Personal belongings such as your jacket, belt and headphones need to go through the machine.
• All your electronic devices, including your laptop and phone, will also need to be scanned.
• Any liquids or gels, such as perfume or hairspray, that you want to bring on board must be no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), zip-lock bag.
• Slip-on shoes are a good footwear choice as you're less likely to have to remove them when passing through security. Big boots and other bulky shoes are often subjected to extra screening.
• Pocket knives and other sharp items are prohibited in the cabin. They'll be confiscated at security, so put them in your checked bags.
