Do you have any tips for my flight to Cascais?
We've pulled together all the info you need to make your flight an enjoyable experience. Follow our tips and you'll be breezing through the airport and seeing the best of Cascais before you know it. What to pack in your hand luggage:

  • The secret to having a pain-free flight experience is to pack in advance. Start with the essentials: passport, boarding pass, credit cards and important medications. Next, bring items that'll help while away those hours, like some electronic gadgets or a thrilling book. It's also wise to pack your chargers, a neck pillow and a pair of earphones. Finally, don't forget to pop in toiletry items like a toothbrush, cleansing wipes and a clean set of clothes.

Do not pack the following items in your hand luggage:

  • Double-check that you don't have sharp objects (like a pocket knife) lurking in your carry-on luggage. Other prohibited items include explosive or flammable products, such as bleach and fuel, and liquids and gels in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Your aim is to be as comfortable as you can. Opt for slip-on footwear, dress in loose, natural-fibre clothing and don't forget to bring a jacket in case it gets cold in the cabin.
  • Caused by sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect passengers on long-distance flights. Lower your risks by drinking water, keeping your legs and ankles moving and wearing compression socks to help improve your circulation.

How to get through airport security fast when flying to Cascais?
As seasoned travellers know, the secret is to be prepared before you arrive at security. That way, you'll be boarding that plane to Cascais in no time flat. Follow these helpful tips and get your trip off to a spectacular start:

  • Security personnel first need to know that you have a valid ID and matching travel documents before you can proceed any further. Have them in your hand, ready for inspection.
  • Next up is the X-ray machine. Remove anything on you that is likely to set off the alarm. This includes items like headphones or earphones, as well as heavy coats or jackets. They'll need to be placed on the conveyor belt for screening.
  • All your electronic devices, including your phone and tablet, will also need to be separately scanned.
  • Any gels or liquids, such as lip balm or cologne, that you want to bring on board need to be in containers no greater than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-lock bag.
  • Slip-on shoes are a clever footwear choice as you're less likely to be asked to remove them when going through security. Safety boots and other heavy shoes are often subjected to extra screening.
  • Airlines won't allow any sharp objects in your carry-on baggage. If you must bring these kinds of items, pack them safely in your checked luggage.
