How to survive the flight to San Carlos?
We've rounded up all the info you need to make your journey an enjoyable experience. Follow our tips and you'll be zooming through the airport and discovering San Carlos in no time flat.What to pack in your hand luggage:

  • The trick to having a pain-free flight experience is to plan ahead. Start with the essentials: passport, official ID, credit cards and any vital medications. Next, take on board items that'll help keep you occupied, like some electronic devices or a magazine. It's also a wise idea to bring your chargers, a neck pillow and a pair of headphones. Finally, be sure to pop in toiletry items like a toothbrush, cleansing wipes and a fresh set of clothes.

Do not pack the following items in your hand luggage:

  • While the list of prohibited items can differ between airlines, the general rule of thumb is nothing flammable, sharp or explosive. This includes screwdrivers, knives, fuels and bleaching agents. Sports equipment like ice skates, and items that could harm other people, such as firearms and ammunition, won't be allowed on board either.

What to wear on a flight:

  • The best way to ensure a comfortable flight often lies in the clothes you wear. Prepare for temperature changes by layering up. This will keep you nice and warm if the cabin gets chilly. Shoes like high heels and sandals are best left in your checked suitcase. Even though they may be your favourites, opt for flat, closed-toed footwear like slip-ons. Your feet will appreciate it.
  • The result of lengthy periods of inactivity, deep vein thrombosis (DVT) is a blood clot condition that can affect some passengers during long flights. The good news is there are ways to reduce your risk of developing it. Stay well hydrated, wander around the cabin as much as possible and wear compression socks to help improve your circulation.

How to get through airport security fast when flying to San Carlos?
The secret is to be well organised before you reach security. That way, you'll be hopping onto that plane to San Carlos in no time flat. Follow these helpful tips and get your trip off to a terrific start:

  • First things first. Your passport and boarding pass will need to be shown to security personnel. Keep them handy so you don't hold up the queue.
  • Next up is the X-ray machine. Remove anything metal on you that is likely to set off the alarm. This includes items like earphones or headphones, as well as bulky coats or jackets. They'll all need to go on the X-ray conveyor belt.
  • All electronic gadgets, including your laptop and phone, are also required to be scanned separately.
  • Don't forget to remove gels and liquids from your hand luggage. They usually need to be sent through the X-ray machine separately. Each item should be no larger than 3.4 ounces (100 milliliters) and everything must fit in a single quart-size (one litre), clear zip-lock bag.
  • There's a chance you'll be asked to remove your shoes to be X-rayed, so wearing lightweight sneakers is always a clever idea.
  • Airlines won't allow any sharp or pointed objects in your carry-on luggage. If you need to bring these kinds of items, pack them safely in your checked luggage.
