Do you have any tips for my flight to Sines?
We've pulled together all the info you need to make your flight as enjoyable as possible. Follow our insider tips and you'll be breezing through airport security and having a ball in Sines in no time flat. What to pack in your hand luggage:

  • The secret to having a great travel experience is to plan ahead. So, let's start with the basics: passport, boarding pass, cash and vital medications. Next, bring items that'll help keep you entertained, like your laptop or a thrilling novel. It's also wise to bring your chargers, a neck pillow and a pair of earphones. Finally, be sure to squeeze in toiletry items like a toothbrush, lip balm and a spare change of clothes.

Do not pack the following items in your hand luggage:

  • Check carefully that you don't have sharp objects (like a pocket knife) lurking in the bottom of your hand luggage. Other banned items include flammable or explosive goods, such as aerosol cans and bleach, and liquids and gels in containers with a volume of more than 3.4 ounces (100 millilitres).

What to wear on a flight:

  • Go for comfort over style. Prepare for changes in cabin temperature by donning layers, and pick flat, closed-toe footwear like slip-ons.
  • Deep vein thrombosis (DVT), a blood clot condition caused by extended periods of inactivity, can be a risk on long-haul flights. Wander around the cabin and stretch your legs or do some simple exercises in your seat to improve your circulation.

How to get through airport security fast when flying to Sines?
As seasoned travellers know, the secret is to be well organised before you arrive at airport security. That way, you'll be hopping onto that plane to Sines before you know it. Follow these tips and get your trip off to a great start:

  • Your travel ID and boarding pass will need to be inspected by airport security personnel. Keep them handy so you don't have to dig around for them.
  • After that, both you and your hand luggage will be X-rayed. To make the process quick and painless, remove anything that might set the alarms off. Personal belongings such as your jacket, belt and headphones need to go through the machine.
  • Your electronic devices like phones and laptops will also have to go through the machine for inspection. No need to worry though, you'll be back online before you know it.
  • Travelling with a new hand and nail cream? As long as it's in a container no larger than 3.4 ounces (100 millilitres) and it's stored in a zip-lock bag, you can keep it with you in your carry-on.
  • Slip-on shoes are a clever footwear choice as you're less likely to be required to remove them when passing through security. Hiking boots and other bulky shoes are often subjected to additional screening.
  • Sharp items are prohibited in the cabin. They'll be seized at security, so put them in your checked suitcase.
