Do you have any tips for my flight to San Marcos?
Depending on where you're coming from, your journey to San Marcos could be a breeze or it could drag on forever. We've put together some useful hints that will help you start your next big adventure on the right foot. What to pack in your hand luggage:

  • The trick to having a great travel experience is to pack ahead. So, let's start with the basics: passport, travel docs, bank cards and medications. Next, take on board items that'll help keep you busy, like some electronic devices or a good read. It's also wise to pack your chargers, a neck pillow and a pair of noise-cancelling headphones. Last but not least, don't forget to chuck in toiletry items like a toothbrush, deodorant and a fresh change of clothes.

Do not pack the following items in your hand luggage:

  • Squeeze all your full-sized bottles of shampoo and hair gel in your checked baggage. 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 goods which are flammable or explosive, such as flares, bleaching agents and gasoline, are also not allowed.

What to wear on a flight:

  • Comfort should be your top priority when deciding what to wear on board. Loose, breathable clothing is a wise option, as are flat, slightly roomy shoes.
  • You're probably aware of deep vein thrombosis (DVT), a blood clotting condition caused by long periods of sitting. To minimize your risk on board, drink lots of water, consider wearing compression socks or tights and move your legs and feet often.

How to get through airport security fast when flying to San Marcos?
The simple answer is --- be prepared. We've rounded up some handy tips and tricks for a fuss-free trip through security. Look out San Marcos, here you come:

  • First things first. Your boarding pass and passport will need to be inspected by airport security personnel. Keep them handy so you don't hold up the queue.
  • Time to strip down. Well sort of. Your belt, coat, keys and other contents of your pockets, like coins, will be required to go through the X-ray machine. Make the whole process faster by removing them as your turn draws near.
  • Your electronic devices like laptops and phones will also have to go on a tray to be scanned. No need to worry though, you'll be back online before you know it.
  • Remove gels and liquids from your carry-on bag. 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 inside a quart-size (one litre), clear zip-close bag.
  • The right choice of footwear can save you several minutes. Boots are often required to be removed and separately scanned. Slip-on sneakers usually aren't.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, pack them in your checked suitcase. They won't be allowed in the cabin.
