Do you have any tips for my flight to San Marcos?
We've pulled together all the info you need to make your flight as pain-free as possible. Follow our tips and you'll be cruising through the airport and enjoying San Marcos in no time flat. What to pack in your hand luggage:
  • A plane ride can be a great experience if you've got all the right things. Firstly, you'll want some basic toiletries, such as deodorant and a toothbrush, a spare pair of socks and something to read. Next, leave space in your hand luggage for your phone and charger, your important medications and perhaps a comfy neck pillow as well. Lastly, and most importantly, be sure 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 hairspray in your checked baggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated by security. Pointed or sharp objects, like your treasured pocket knife, and dangerous goods which are flammable or explosive, such as aerosols and matches, are also not allowed.
What to wear on a flight:
  • Your goal here is to be as comfortable as possible. Go for a pair of slip-on shoes, dress in loose, natural-fibre clothing and don't forget to bring a sweater in case it gets cold in the cabin.
  • Deep vein thrombosis (DVT) is a risk on long-haul flights. It results from blood clotting due to poor circulation, so do some gentle leg and foot exercises in your seat and consider wearing compression socks.
How to get through airport security fast when flying to San Marcos?
A little pre-planning before you get to the airport will help make your trip to San Marcos a piece of cake. Check out our handy tips for a stress-free journey past security:
  • Keep your boarding pass and passport someplace easily accessible. They'll be the first things you'll be asked to show at airport security.
  • The X-ray machine comes next. Remove anything metal on you that is likely to set off the scanner's alarm. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • Your electronic gadgets like laptops and phones will also have to go through the machine to be scanned. Don't worry, you'll be back online before you know it.
  • Remember to remove liquids and gels from your carry-on luggage. They usually 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 in a quart-size (one litre), clear zip-lock bag.
  • The right choice of footwear can save you a few precious minutes. Boots and bulky shoes are often required to be removed and separately scanned. Slip-on sneakers are usually not.
  • Avoid taking prohibited items in your carry-on bag. If you have any sharp objects like a pocket knife or tools, put them in your checked suitcase. They won't be allowed on board.
