Cheap Flights to South Portland from HK$1,710

We've rounded up all the info you need to make your flight an enjoyable experience. Follow our top tips and you'll be breezing through the airport and having a blast in South Portland before you know it. What to pack in your hand luggage:

• First things first, pack your passport, travel documents, bank cards and medications. Next, you'll want some entertainment to while away the hours. A juicy novel and a laptop filled with your favourite shows are good options. If you hope to take a quick snooze, a neck pillow and a pair of noise-cancelling headphones will also come in handy. Finally, find room for a few toiletry items to ensure you arrive at your destination looking and feeling fresh.

Do not pack the following items in your hand luggage:

• While the list of banned items can differ between airlines, the general rule of thumb is nothing flammable, sharp or explosive. This includes things like screwdrivers, blades, fuels and bleaching agents. Sports equipment like hockey sticks, and items that could injure passengers, such as pepper spray and guns, won't be allowed on board 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 pick flat, enclosed footwear like sneakers.
• Deep vein thrombosis (DVT), a blood clot condition caused by lengthy periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some gentle exercises in your seat to promote better circulation.

It's all about being organised. We've rounded up some top tips for a stress-free trip through airport security. Look out South Portland, here you come:

• Be sure to have your travel documents and passport within close reach. They'll be the first things you'll be asked for by airport security.
• Next up, both you and your carry-on bag must be X-rayed. To make the process quick and painless, remove anything that is likely to set the alarm off. Personal belongings like your coat, belt and headphones will be required to go through the machine.
• For just a few minutes, you'll have to unplug from the digital world. Your phone, laptop and any other electronics will also need to be sent through the scanner.
• Remove all liquids and gels from your carry-on bag. They usually need to be sent through the X-ray separately. Each item should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-close bag.
• Lightweight sneakers are a good footwear choice as you're less likely to be required to remove them when passing through security. Safety boots and other heavy-style shoes are often subjected to extra screening.
• Sharp items are not allowed on board. They'll be confiscated at security, so pack them safely away in your checked bags.
