Do you have any tips for my flight to Lake San Marcos?
Depending on where you're coming from, your trip to Lake San Marcos could be completely painless or it could go on forever. Here are some handy tips that will help you start your unforgettable escape on the right foot. What to pack in your hand luggage:

  • The secret to having a great flight experience is to be prepared. Start with the essentials: passport, travel docs, credit cards and any vital medications. Next, bring on board items that'll help keep you occupied, like your laptop or a good book. It's also a wise idea to bring your chargers, a comfy neck pillow and a pair of noise-cancelling headphones. And of course, be sure to toss in toiletry items like a toothbrush, lip balm and a spare set of clothes.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of hair gel and hairspray in your checked baggage. Any liquids or gels in your carry-on bag larger than 3.4 ounces (100 millilitres) will be confiscated by security. Pointed or sharp objects, like your beloved pocket knife, and dangerous goods which are explosive or flammable, such as aerosols and gasoline, are also banned.

What to wear on a flight:

  • The aisles of an aircraft are no place for a fashion parade. Wear layers and pick shoes that are flat and easy to slip on and off.
  • Most of us have heard about deep vein thrombosis (DVT), a blood clotting condition caused by long periods of sitting. To lessen your risk on board, stay hydrated, consider wearing compression socks or tights and move your legs and feet often.

How to get through airport security fast when flying to Lake San Marcos?
Being prepared before you get to the airport will help make your getaway to Lake San Marcos a pleasure. Here are some useful tips and tricks for a stress-free journey past security:

  • First things first. Your boarding pass and passport will need to be inspected by airport security. Keep them within easy reach to avoid fumbling around for them.
  • Next up, both you and your carry-on bag must be X-rayed. To speed things up, take off anything that might trigger the alarms. Items such as your belt, coat and earphones will be required to go through the machine.
  • All your electronic gadgets, including your phone and laptop, are also required to be scanned.
  • Remove all liquids and gels from your carry-on bag. They often need to be sent through the X-ray machine separately. Each product should be in a container no larger than 3.4 ounces (100 millilitres) and everything must fit inside a quart-size (one litre), clear zip-close bag.
  • The right choice of footwear can save you a few precious minutes. Boots and bulky shoes are often required to be removed and X-rayed separately. Lightweight sneakers usually aren't.
  • Airlines won't allow any sharp or pointed objects in the cabin. If you need to bring these kinds of items, put them in your checked luggage.
