Do you have any tips for my flight to San Carlos?
Depending on where you're coming from, your flight to San Carlos could be no sweat at all or it could go on forever. We've pulled together some useful travel tips that will help you start your next great escape on the right foot. What to pack in your hand luggage:

  • Travelling on a plane can be a stress-free experience if you take the right things. First things first, you'll need toiletry items, such as deodorant, toothpaste and a toothbrush, a spare pair of socks and a good read. Next, find a spot in your carry-on bag for your mobile phone, a charger, your medications and maybe a quality neck pillow too. Last, but definitely not least, be sure to bring your passport, travel documents and some money.

Do not pack the following items in your hand luggage:

  • Put all your full-sized bottles of shampoo and hairspray in your checked baggage. Any liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Pointed or sharp objects, like your precious Swiss Army knife, and products which are flammable or explosive, such as aerosol cans, flares and poisons, are also restricted.

What to wear on a flight:

  • Comfort should be your highest priority when deciding what to wear during your flight. Loose, breathable clothing is a sensible choice, as are flat, enclosed shoes.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by prolonged inactivity, can be a risk on long-haul flights. Try to walk around the cabin and stretch your legs or do some gentle exercises in your seat to promote better circulation.

How to get through airport security fast when flying to San Carlos?
The secret is to be prepared before you reach airport security. That way, you'll be stepping onto that plane to San Carlos in next to no time. Follow these tips and get your holiday off to a flying start:

  • First things first. Your travel documents and ID will need to be presented to security personnel. Keep them someplace accessible so you don't hold up the line.
  • Your jacket, belt, keys and other contents of your pockets, like coins, will need to go through the X-ray machine. Make the whole process faster by removing them before your turn arrives.
  • Your electronic gadgets like phones and laptops will also need to go on a tray to be scanned. Don't worry, you'll be back online soon enough.
  • Travelling with a new cologne? No problem. As long as the volume is no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you can keep it with you in your carry-on baggage.
  • There's a chance you'll be required to remove your shoes for scanning, so wearing slip-on shoes is always a good idea.
  • 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 luggage. They won't be allowed in the cabin.
