Do you have any tips for my flight to San Marcos?
If you're not prepared, travelling can be overwhelming. But there's no need to hit the panic button just yet. Follow these handy tips and enjoy a stress-free start to your getaway in San Marcos. What to pack in your hand luggage:

  • The secret to having a worry-free flight experience is to pack ahead. So, let's start with the basics: passport, official ID, bank cards and daily medications. Next, take on board items that'll help keep you entertained, like some electronic devices or a few magazines. It's also a wise idea to bring your chargers, a quality neck pillow and a pair of earphones. Finally, don't forget to toss in toiletries like a toothbrush, deodorant and a clean set of clothes.

Do not pack the following items in your hand luggage:

  • Leave all your full-sized bottles of shampoo and hair gel in your checked luggage. Any gels or liquids in your carry-on bag larger than 3.4 ounces (100 millilitres) won't be allowed on. Pointed or sharp objects, like your trusty Swiss Army knife, and products which are flammable or explosive, such as flares, bleaching agents and strong acids, are also restricted.

What to wear on a flight:

  • You'll want to choose comfort over style. Prepare for temperature changes by wearing layers, and opt for flat, slightly roomy footwear like sneakers.
  • Most of us have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To reduce your risk on board, drink lots of water, consider wearing compression socks or tights and keep your feet and legs moving.

How to get through airport security fast when flying to San Marcos?
The secret is to be organized before you arrive at airport security. That way, you'll be stepping onto that plane to San Marcos in no time at all. Follow these helpful tips and get your vacation off to a terrific start:

  • Be sure to have your travel documents and passport someplace easily accessible. They're the first things you'll be asked to show at security.
  • Time to strip down. Well kind of. Your belt, coat, keys and other contents of your pockets, like your earphones, will need to go on a tray through the X-ray machine. Make the whole process easier by removing them before your turn arrives.
  • Your electronic gadgets like laptops and phones will also have to go on a tray for inspection. No need to worry though, you'll be back online in no time.
  • Travelling with your favourite hand and nail cream? Not a problem. As long as the volume is no greater than 3.4 ounces (100 millilitres) and it's stored in a zip-close bag, you can bring it with you in your carry-on baggage.
  • Lightweight sneakers are a practical footwear choice as you're less likely to be required to remove them when passing through security. Safety boots and other bulky shoes are often subjected to extra screening.
  • Airlines won't allow any sharp items or pocket knives to come on board with you. If you must bring these kinds of items, pack them safely in your checked baggage.
