Do you have any tips for my flight to Lake San Marcos?
Depending on where you're coming from, your journey to Lake San Marcos could be a breeze or it could drag on forever. We've rounded up some handy tips that will help you start your next unforgettable escape on a positive note. What to pack in your hand luggage:

  • A plane ride can be a comfortable experience if you bring the right gear. First of all you'll need basic toiletry items, such as toothpaste, a toothbrush and some deodorant, a spare change of clothes and a magazine or two. Next, find a spot in your bag for your electronic devices, chargers, any daily medications and maybe a neck pillow too. Last, but definitely not least, remember to take your passport, travel documents and some money.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hair gel in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by authorities. Pointed or sharp objects, like your beloved Swiss Army knife, and dangerous goods which are explosive or flammable, such as flares, chemicals agents and strong acids, are also restricted.

What to wear on a flight:

  • Your aim here is to feel as comfortable as possible. Pick a pair of slip-on shoes, dress in loose, natural fibers and remember to bring a pullover in case it gets cold in the cabin.
  • Caused by prolonged periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect passengers during long-haul flights. Reduce the risks by staying hydrated, keeping your ankles and legs moving and wearing compression tights or socks.

How to get through airport security fast when flying to Lake San Marcos?
A little pre-planning before your flight will make your trip to Lake San Marcos a pleasure. We've rounded up some handy hints for a stress-free journey through security:

  • Be sure to have your ID and travel documents easily accessible. They'll be the first things you'll be asked for by security.
  • After that, both you and your hand luggage must be X-rayed. To speed things up, take off anything that might trigger the alarms. Personal belongings like your coat, belt and earphones will be required to go through the machine.
  • Your electronic gadgets like laptops and phones will also have to go on a tray for inspection. Don't worry, you'll be back online soon enough.
  • Remove gels and liquids from your carry-on luggage. They often need to be sent through the X-ray separately. Each item should be no larger than 3.4 ounces (100 millilitres) and everything must fit in a quart-size (one litre), clear zip-lock bag.
  • Choosing your footwear wisely can save you several minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. Slip-on shoes are usually not.
  • Airlines won't allow any sharp or pointed objects in your hand luggage. If you need to bring these kinds of items, pack them in your checked luggage.
