Cheap Flights to Sines from HK$318

Depending on where you're coming from, your flight to Sines could be no sweat at all or it could drag on forever. We've compiled some useful hints that will help you start your next great escape on a positive note.What to pack in your hand luggage:

• First and foremost, pack your passport, travel documents, credit cards and medications. Next, you'll want some extra in-flight entertainment to while away the time. A juicy novel and a tablet crammed with your favorite shows are good options. If you intend to take a short nap, a neck pillow and some earplugs will also be useful. Finally, leave space for a few toiletry items so you'll hop off the plane feeling fresh and raring to go.

Do not pack the following items in your hand luggage:

• Check carefully that you don't have a Swiss Army knife lurking in the bottom of your hand luggage. Other banned items include explosive or flammable goods, such as fuel and matches, and liquids and gels in containers larger than 3.4 ounces (100 milliliters).

What to wear on a flight:

• The best way to ensure a comfortable flight is often as simple as the clothes you wear. Prepare yourself for varying temperatures by layering up. This will keep you nice and warm if the cabin starts to cool down. Shoes like high heels and sandals are best left for other occasions. Instead, go for flat, closed-toed footwear like slip-ons. Your feet will appreciate it.
• Most travelers are aware of deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. There's plenty you can do to lessen your risk. Wear a pair of compression socks, drink lots of water and remember to keep your legs and feet moving. Do a few laps of the cabin or perform exercises in your seat.

Being organized before your flight will help make your trip to Sines a breeze. We've rounded up some handy tips and tricks for a stress-free journey through security:

• First things first. Your passport and travel documents will need to be shown to airport security. Have them close by so you don't hold up the line.
• Next up is the X-ray machine. Remove anything on you that is likely to set off the scanner's alarm. This includes items like earphones or headphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
• Electronic devices like phones and laptops will also have to go through the machine for inspection. No need to worry though, you'll be back online soon enough.
• Remember to remove liquids and gels from your hand luggage. 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 single quart-size (one liter), clear zip-lock bag.
• The right choice of footwear can save you several precious minutes. Hiking boots are often required to be removed and X-rayed separately. Slip-on shoes are usually not.
• Airlines will not allow any pocket knives or other sharp items in your carry-on luggage. If you must bring these kinds of items, pack them in your checked luggage.
