Do you have any tips for my flight to Cascais e Estoril?
We've got the lowdown on how to make your flight a stress-free experience. Follow our tips and you'll be breezing through airport security and exploring Cascais e Estoril in no time. What to pack in your hand luggage:

  • Travelling on a plane can be easy if you bring the right stuff. Firstly, you'll want a few basic toiletry items, such as a toothbrush and some deodorant, a spare pair of socks and a magazine or two. Secondly, make room in your hand luggage for your electronic gadgets, chargers, any daily medications and perhaps a neck pillow as well. Lastly, and most importantly, be sure to bring your passport, travel papers and your credit cards.

Do not pack the following items in your hand luggage:

  • While the list of restricted items can differ between airlines, the general rule to follow is avoid carrying anything sharp, flammable or explosive. This includes screwdrivers, blades, spray paint and flares. Sports equipment like baseball bats, and items that could harm passengers, such as swords and batons, can't come on board with you either.

What to wear on a flight:

  • Comfort should be your top priority when deciding what to wear during your flight. Loose clothing is a smart option, as are enclosed shoes like sneakers.
  • Deep vein thrombosis (DVT), a blood clotting condition caused by extended periods of inactivity, can be a risk on long-haul flights. Try to walk around the cabin or do some gentle exercises in your seat to promote better circulation.

How to get through airport security fast when flying to Cascais e Estoril?
Being organised before you get to the airport can make your trip to Cascais e Estoril a piece of cake. We've rounded up some top tips for a speedy journey through security:

  • First things first. Your travel documents and ID will need to be inspected by security personnel. Have them easily accessible so you don't hold up the queue.
  • Time to strip down. Well kind of. 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 easier by removing them as it gets closer to your turn.
  • Your electronic gadgets like laptops and phones will also have to go on a tray for inspection. No need to worry though, you'll be back online before you know it.
  • Any gels or liquids, such as perfume or hairspray, that you want to take on board must be no greater than 3.4 ounces (100 millilitres). Also, they all must fit inside a quart-size (one litre), clear zip-lock bag.
  • Choosing your footwear wisely can save you several precious minutes. Boots are often required to be removed and X-rayed separately. Slip-on shoes usually aren't.
  • Airlines won't allow any pocket knives or other sharp items in your carry-on luggage. If you must bring these kinds of items, put them in your checked luggage.
