Cheap Flights to San Marcos from HK$283

If you're not prepared, air travel can be testing. But there's no need to panic. Follow these helpful hints and enjoy a stress-free start to your holiday in San Marcos. What to pack in your hand luggage:

• It's simple — first, put in your passport, travel docs, cash and medications. Next, you'll want some entertainment to while away the time. A thrilling book and a laptop crammed with your favourite movies are some great options. If you plan to take a short nap, a neck pillow and some earplugs will also come in handy. Finally, squeeze in a toothbrush and some cleansing wipes to ensure you step off the plane looking fresh and raring to go.

Do not pack the following items in your hand luggage:

• Leave all your full-sized bottles of shampoo and hairspray in your checked luggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp objects, like your trusty pocket knife, and dangerous products which are explosive or flammable, such as aerosol cans, spray paint and fuels, are also restricted.

What to wear on a flight:

• The aisles of an airplane aren't the place for a fashion parade. Layer your clothing and opt for shoes that are closed-toe, flat and easy to slip on and off.
• Most travellers are aware of deep vein thrombosis (DVT), a blood clot condition caused by long periods of sitting. To reduce your risk on board, drink lots of water, consider wearing compression socks or tights and do gentle foot and leg exercises in your seat.

The answer is simple — be prepared. We've compiled some tips and tricks for a speedy trip through airport security. Watch out San Marcos, here you come:

• First things first. Your boarding pass and passport will need to be shown to airport security personnel. Keep them handy to avoid fumbling around for them.
• Your belt, coat, keys and other contents of your pockets, like your earphones, will need to go through the X-ray machine. Make your life easier by removing them as it gets closer to your turn.
• Electronic devices like laptops and phones will also need to go on a tray to be scanned. Don't worry though, you'll be back online soon enough.
• Want to bring along your favourite cologne or perfume? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a clear zip-lock bag, you can bring it with you in your carry-on luggage.
• The right choice of footwear can save you valuable minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Slip-on sneakers usually aren't.
• Knives and other sharp items are prohibited in the cabin. They'll be seized at security, so pack them in your checked luggage.
