Do you have any tips for my flight to Santiago do Cacém?
Depending on where you're coming from, your flight to Santiago do Cacém could be completely painless or it could drag on forever. Below are some handy hints that will help you start your next great adventure on the right foot. What to pack in your hand luggage:
  • A plane trip can be a comfortable experience if you take the right things. Firstly, you'll need basic toiletry items, such as a toothbrush and some deodorant, a spare set of clothes and a magazine or two. Next, find a spot in your bag for your electronic gadgets, chargers, medications and perhaps a quality neck pillow as well. Lastly, and most importantly, remember to take your passport, travel docs and your bank cards.
Do not pack the following items in your hand luggage:
  • Leave all your full-sized bottles of hair gel and hairspray in your checked luggage. Any liquids or gels in your carry-on suitcase larger than 3.4 ounces (100 millilitres) won't be allowed on. Sharp or pointed objects, like a pocket knife, and dangerous goods which are flammable or explosive, such as flares, bleaching agents and poisons, are also prohibited.
What to wear on a flight:
  • Your priority is to be as comfortable as possible. Opt for a pair of slip-on shoes, dress in loose, natural fibers and remember to take a jacket in case it gets chilly in the cabin.
  • It's likely you've heard about deep vein thrombosis (DVT), a blood clot condition caused by long periods of inactivity. To lower your risk on board, stay hydrated, consider wearing compression tights or socks and keep your feet and legs moving.
How to get through airport security fast when flying to Santiago do Cacém?
Being organized before your flight will help make your trip to Santiago do Cacém a breeze. Read through our handy hints for a stress-free journey through security:
  • Have your ID and boarding pass someplace easily accessible. They're the first items you'll be asked to show at security.
  • After that, both you and your carry-on luggage will be X-rayed. To speed things up, take off anything that might set the alarms off. Personal belongings such as your coat, belt and earphones will be required to go through the machine.
  • For just a few minutes, you'll need to unplug from the digital world. Your phone, tablet and any other electronics must also go through the scanner.
  • 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 clear zip-lock bag, you're permitted to bring it with you in your carry-on luggage.
  • Choosing your footwear wisely can save you a few precious minutes. Hiking or heavy-style boots are often required to be removed and X-rayed separately. 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 baggage. They won't be allowed on board.
