Cheap Flights to San Sebastián from HK$3,749

If you're poorly prepared, traveling can be testing. But don't hit the panic button just yet. Follow these handy hints for a stress-free start to your vacation in San Sebastián.What to pack in your hand luggage:

• Firstly, and most importantly, pack your passport, official ID, cash and medications. Next, you'll want some in-flight entertainment to help pass the time. A thrilling novel and a phone crammed with your favorite shows are some wonderful options. If you hope to catch a few z's, a neck pillow and a pair of earplugs will also be useful. Finally, squeeze in a few toiletry items so you'll step off the plane feeling fresh and ready to go.

Do not pack the following items in your hand luggage:

• Pack all your full-sized bottles of shampoo and conditioner in your checked baggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 milliliters) will be confiscated. Pointed or sharp objects, like your beloved Swiss Army knife, and dangerous goods which are flammable or explosive, such as spray paint, flares and fireworks, are also restricted.

What to wear on a flight:

• Your number one priority is to feel as comfortable as possible. Layer up in natural fibers and don't forget to pack a cardigan just in case you get cold. Always go with flat, slightly roomy shoes as your feet may swell a little during the flight. Leave the stilettos and heavy hiking boots in your checked baggage.
• Unfortunately, a risk of long-distance flying is developing DVT (deep vein thrombosis), a blood clot condition caused by extended periods of inactivity. To prevent this from happening, make the most of every opportunity to walk around and give your legs a stretch. Compression socks and tights are also a great idea to help minimize this risk.

As seasoned travelers know, the secret is to be organized before you reach security. That way, you'll be stepping onto that plane to San Sebastián in the blink of an eye. Follow these tips and get your trip off to a spectacular start:

• Your travel documents and ID will need to be shown to security personnel. Keep them someplace accessible so you don't hold up the queue.
• Time to strip down. Well sort of. Your belt, jacket, keys and other items in your pocket, like coins, will need to go on a tray through the X-ray machine. Make the whole process faster by removing them as it gets closer to your turn.
• All electronic devices, including your phone and tablet, are also required to be separately scanned.
• Traveling with your favorite cologne? As long as the volume is no greater than 3.4 ounces (100 milliliters) and it's stored in a clear zip-close bag, it's fine to bring with you in your carry-on luggage.
• Slip-on shoes are a clever footwear choice as you're less likely to have to remove them when going through security. Big boots and other heavy shoes are usually subjected to additional screening.
• Airlines will not allow any sharp objects in your carry-on baggage. If you need to bring these kinds of items, put them in your checked baggage.
