Do you have any tips for my flight to Casais?
If you're poorly prepared, airports and flying can be tough. But there's no need to hit the panic button just yet. Follow these handy hints and enjoy a hassle-free start to your getaway in Casais. What to pack in your hand luggage:

  • First and foremost, pack in your passport, travel docs, wallet and vital medications. Next, you'll want some in-flight entertainment to while away the hours. A juicy novel and a phone filled with your favourite movies are some great options. If you intend to catch more than just forty winks, a neck pillow and some noise-cancelling headphones will also come in handy. Finally, squeeze in a toothbrush and some cleansing wipes to ensure you arrive looking and feeling fresh.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have sharp objects (like a knife or scissors) hiding in one of the compartments of your hand luggage. Other prohibited items include flammable or explosive products, such as fuel and matches, and gels and liquids in containers with a capacity of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Go for comfort over style. Prepare for temperature changes in the cabin by wearing layers, and wear flat, enclosed shoes like slip-ons.
  • Caused by sustained periods of inactivity, deep vein thrombosis (DVT) is a blood clotting condition that can affect some passengers on long-distance flights. Reduce the risks by drinking water, keeping your ankles and legs moving and wearing compression socks or tights.

How to get through airport security fast when flying to Casais?
Being organised before you get to the airport will help make your getaway to Casais a piece of cake. Below are some handy tips and tricks for a stress-free journey past security:

  • Airport security personnel first need to establish that you have a valid passport and matching boarding pass before anything else. Have them in your hand, ready for inspection.
  • Next up is the X-ray machine. Remove anything metal on you that is likely to beep. This includes items like headphones or earphones, as well as your coat or jacket. They'll all need to go on the X-ray conveyor belt.
  • All your electronic devices, including your phone and laptop, must also be separately scanned.
  • Any gels or liquids, such as perfume or hairspray, that you want to take on board must be no larger than 3.4 ounces (100 millilitres). Also, everything must fit inside a quart-size (one litre), clear zip-close bag.
  • Choosing your footwear wisely can save you valuable minutes. Boots are often required to be removed and separately scanned. Slip-on sneakers usually aren't.
  • Airlines won't allow any sharp or pointed objects in your carry-on baggage. If you must bring these kinds of items, put them in your checked baggage.
