Frequently asked questions

How to book the cheapest flight to San Carlos?
Don't leave booking your flight to San Carlos until the last minute. That's one trick seasoned travellers use to get the best prices. Booking ahead means more choices and more affordable flights. Another fantastic way to score the most competitive fare is to compare all options. If your destination has a few airports, don't forget to look into the cost of flying into a smaller terminal. Last of all, be ready to lock in your seat quickly if you find an irresistible price. It might not be available for too long! With a bit of knowledge and some luck, the perfect airfare can be yours.
Do you have any tips for my flight to San Carlos?
We've rounded up all the info you need to make your flight as enjoyable as possible. Follow our top tips and you'll be cruising through the airport and exploring San Carlos in no time at all. What to pack in your hand luggage:
  • The trick to having an amazing travel experience is to be prepared. First up, the essentials: passport, boarding pass, credit cards and important medications. Next, bring items that'll help pass the time, like your laptop or a juicy novel. It's also wise to pack your chargers, a quality neck pillow and a pair of noise-cancelling headphones. Finally, be sure to chuck in toiletry items like a toothbrush, cleansing wipes and a spare set of clothes.
Do not pack the following items in your hand luggage:
  • Put all your full-sized bottles of shampoo and conditioner in your checked baggage. Any gels or liquids in your carry-on suitcase larger than 3.4 ounces (100 millilitres) will be confiscated. Sharp objects, like your Swiss Army knife, and dangerous products which are flammable or explosive, such as flares, bleaching agents and fuels, are also not allowed.
What to wear on a flight:
  • Comfort should be your main concern when choosing what to wear on your flight. Loose clothing is a smart choice, as are flat, enclosed shoes.
  • Most travellers have heard about deep vein thrombosis (DVT), a blood clot condition caused by prolonged periods of inactivity. To minimize your risk on board, stay hydrated, consider wearing compression tights or socks and move your legs and feet often.
How to get through airport security fast when flying to San Carlos?
A little pre-planning before you arrive at the airport will help make your getaway to San Carlos a piece of cake. We've compiled some useful tips for a swift journey through security:
  • Your passport and travel documents will need to be inspected by airport security personnel. Keep them within easy reach so you don't hold up the line.
  • Next up, both you and your carry-on luggage will be X-rayed. To speed things up, remove anything that is likely to trigger the alarm. Items such as your belt, coat and headphones need to go through the machine.
  • For just a few minutes, you'll need to unplug from the digital world. Your laptop, phone and any other electronics will need to be sent through the scanner.
  • Can't travel without your favourite perfume or 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're allowed to bring it with you in your carry-on baggage.
  • Lightweight sneakers are a practical footwear choice as you're less likely to be asked to remove them when going through security. Boots and other heavy-style shoes are often subjected to extra screening.
  • Take all prohibited items out of your carry-on bag. If you have any sharp or pointed objects, pack them in your checked luggage. They won't be allowed on board and will be confiscated.
